Our experimental results by multinuclear spin relaxation techniques were then compared with molecular dynamics computations for water and ions in concentrated electrolyte solutions (LiCl.R(H2O)R(D2O) and NaCl.R(H2O)/R(D2O), with 4 < R < 12 for Li+ and 6 < R < 16 for NaCl). Multinuclear spin relaxation data were analyzed with a thermodynamic linkage model of hydrated ion clusters of various sizes and composition. Our results indicate that tetramer clusters of hydrated Li+ and Cl- are the preferred structures formed in such concentrated electrolyte solutions as a consequence of dimertetramer equilibria that occur at 293 K. Within such clusters water molecules undergo hindered reorientation motions in the hydration shell of the cation. The corresponding correlation time of water (D2O), determined by O-17 NMR, is less than 30 ps for 4 < R < 12 in all solutions studied at 293 K. C1 USDA ARS,EASTERN REG RES CTR,PHILADELPHIA,PA 19118.

Molecular dynamics and multinuclear spin relaxation measurements were carried out for several proteins in order to elucidate the mechanisms for the cationic and anionic interactions with the protein binding sites. Specific interactions of the anions with the positively charged side chain groups of lysine, arginine and histidine, as well as nonspecific binding to amide groups, were found. Both anion- and cation- specific, as well as cooperative, interactions with charged side chain groups were found for myosin, tropomyosin, and for 7S and 11S globulins from soy. The comparison between the O-17 and Na-23 NMR results strongly suggests that water is exchanged as the hydrated ion species between the myofibrillar and/or myosin protein binding sites and the bulk, aqueous solution of electrolytes.

The -OH<->H2O first order exchange rate constant increased from 0.32 to 11.14 s-1 as the molar ratio of H2O:sugar increased from only ca. 4 to 5. The latter finding indicated that the -OH<->H2O proton exchange process, which is proportional to the translational diffusion of water, diminished as H2O approached the concentration which exists in the crystalline structure and was, presumably, entrapped by our glucuronic acid derivative forming a stable complex. Supporting this, a significant upfield shift in the resonance frequencies of the hydroxyl (-OH Delta delta(ave) = 86.33 Hz) protons was observed (CH Delta delta(ave) = 0.25 Hz) when water was removed by reaction with 2,2-dimethoxypropane. Molecular dynamics calculations (100 ps) on the energy-minimized carbohydrate-water complex confirm. the presence of 2-3 near neighbor H2O molecules associated with the polar functional groups. In fact, the computationally-derived weighted average distance of all water molecules adjacent to the -OH groups was found to be inversely proportional to the individual -OH Delta delta s.

Synthetic peptides corresponding to the loop region elicit high levels of specific protective neutralizing antibody. The results of serologic studies have led to the conclusion that a major influence on the antigenicity of the loop is the presence of a Pro residue at position 153. Equally important is the sensitivity of position 148 to the presence of either Leu or Phe. C1 UNIV LONDON,SCH PHARM,DEPT PHARMACEUT CHEM,LONDON WC1N 1AX,ENGLAND.

Dairy Sci 74: 2889, 1991) was constructed using sequence based prediction algorithms in conjunction with global experimental secondary structural information obtained from Raman Spectroscopy. This model is now energy minimized using primarily, the Kollman force field. Both the original and energy minimized structures contain a hydrophilic domain and a hydrophobic domain which are connected by a segment of alpha-helix. However, within the hydrophobic domain, three anti-parallel hydrophobic sheets are in different spatial orientations for the two structures. To mimic the self-association properties of the alpha(s1)-casein B at low ionic strength, a tetramer model was constructed using the largest hydrophobic antiparallel sheets and the hydrophobic ion-pair, which occurs within the deletion peptide of the A variant, as interaction sites. Two tetramers were self associated via hydrophobic sites to model the octamer of alpha(s1)-casein B which occurs at high ionic strengths. All energy minimized working models are in agreement with many of the biochemical, chemical and physico-chemical properties of alpha(s1)-casein A, B and C.

The models for the individual caseins were from previously reported refined, three dimensional structures. Docking of one chi-casein and four alpha(s1)-casein molecules produced a framework structure through the interaction of two hydrophobic antiparallel sheets of chi-casein with two small hydrophobic antiparallel sheets (residue 163-174) of two preformed alpha(s1)-casein dimers. The resulting structure is approximately spherically symmetric, with a loose packing density; its external portion is composed of the hydrophilic domains of the four alpha(s1)-caseins, while the central portion contains two hydrophobic cavities on either side of the chi-casein central structure. Symmetric and asymmetric preformed dimers of beta-casein formed from the interactions of C terminal beta-spiral regions as a hinge point, could easily be docked into each of the two central cavities of the alpha-chi-framework. This yielded two energy minimized three dimensional structures for submicellar casein, one with two symmetric beta-casein dimers and one with two asymmetric dimers. These refined submicellar structures were tested by generating theoretical small-angle X-ray scattering (SAXS) curves and comparing them with experimental data. Agreement between experimental and theoretical curves was best when 120 bound water molecules were included. Comparison of SAXS data with the theoretical curves generated from X-ray data for bovine pancreatic trypsin inhibitor, by the same programs, gave similar results.

Specifically, the mechanism for the anionic or cationic interactions with either backbone or side chain groups on the protein is still speculative. We initiated molecular dynamics, MD, calculations to clarify this dilemma. MD results for oxytocin in CaCl2 indicate anions H-bond to the peptide N-H backbone causing a conformational change (from turn and extended structure to loop); which is in agreement with the FTIR spectroscopy of oxytoxin. MD calculations on predicted and energy minimized structures of a tropocollagen template molecule in aqueous CaCl2 suggest that Ca2+ or Cl- bind to the tropocollagen N-H backbone bonds, but unlike oxytocin stabilizes the structure. Finally, MD calculations on the N-terminal half of native and dephosphorylated alpha(s1)-casein A showed ion binding and hydration energies in agreement with experimental data.

Change in conformer structure and biochemistry affect binding, acylation, and hydrolysis. It is significant that the anionic-esteratic intersite distance is not altered during conformer change as E is converted to EA. In this enzyme system, cationic acetylcholine and anionic AChE are true structural, functional, and biochemical counterparts. The anionic center in the E conformer lies at the bottom of a sterically restricted, hydrophobic cleft <8 Angstrom wide at the top and >3 Angstrom wide at the bottom, while the anionic center in the EA conformer is relatively open. It is characterized by a decrease in the relative binding of hydrophobic cations and by an ability to bind large organic cations. Binding of acetylcholine, H+, or organic cations at the anionic site controls k(2(acylation)) in the E conformer and k(3(hydrolysis)) in the EA conformer. Acetylcholine binding forms the ES complex in which the cation maximizes k(2). In the EAS complex, the cation reduces k(3) and provides allosteric control. Anionic site structure and biochemistry and the effect of pH on k(2) and k(3) differentiates AChE from butyrlcholinesterase. This comprehensive study of kinetic and thermodynamic processes in AChE was made possible by the synthesis and/or use of families of over 30 cationic and acylation probes of known stereochemistry. They act as rulers of the E and EA conformers of AChE and provide comparative data on kinetic-based and thermodynamic-based constants. Cationic inhibitors affect decarbamylation rates in AChE and provide an additional set of comparative data related to the mechanism of substrate hydrolysis by AChE. Acridine araphanes are unique neural receptor and cholinergic enzyme probes. Their parallel plane and coplanar conformations are related to bridge length. Two parallel plane acridine araphanes are pure uncompetitive inhibitors of AChE. Scatchard plots of the binding of methylacridinium and 9-aminoacridine with the E conformer and 9-aminoacridine with the EA conformer indicate binding at a single anionic site. No ternary complex (EII or EAII) from two-site binding was detected. In AChE, nonspecific, low-level binding at surface ionic and hydrophobic areas is ubiquitous. Binding affinity differences greater than two orders of magnitude distinguish binding at the anionic site from low level binding at surface moieties. Surface binding provides environmental and stability changes in the enzyme but does not modify the fundamental biochemistry of the E and conformers. C1 USDA ARS,SAA,HORT RES LAB,ORLANDO,FL 32803.

Branches from the parent hypha envelop the ascogonium, become septate, branch further and produce the nonascogenous portions of the centrum as well as the ascomal wall. The ascogonium wraps around itself in various ways, elongates, and spreads into a flattened layer above the wall at the base of the young ascoma. Ascogenous hyphae, croziers, and asci arise from the ascogonium. Paraphyses form as vertical rows of expanded cells among the ascogenous hyphae. This tissue appears as an area of pseudoparenchyma in sectional view but the rows of cells are separable and, therefore, are equivalent to more typically filamentous paraphyses. The paraphyses are digested as the asci develop and are no longer evident when asci are mature. A small cavity forms just beyond the tips of the paraphyses when the neck and neck canal begin formation. The neck canal is lined with periphyses. Development of the centrum of G. cingulata is shown to be sordariaceous and especially similar to that in Triangularia backusii and Plectosphaerella cucumerina.

We are moving into a new era in which crops will be protected from a broad spectrum of pests including weeds, insects, and diseases by these new biotechnologies. The development of these agents, along with genetically altered pest resistant crops, will provide new means by which crops will be protected from pests in future years. Also addressed here is the evolving approach to pesticide discovery, such as computer-aided design and strategies based on understanding of the underlying biochemical target systems. Finally, the monitoring of these products in the environment, and as a related process, the devising of strategies to regulate them with an appropriate balance between safety and the encouragement of innovation are discussed.

Their original discovery occurred almost simultaneously in Japan and America, respectively in Distylium racemosum, ''Isunoki,'' an evergreen tree and in canola (Brassica napus) pollen. Extracts from 227 kg canola pollen, gathered by bees, gave America the lead in the field and the structure of brassinolide was determined. There followed an intense search for sources of brassinosteroids in plants and by chemical synthesis, especially in Japan and Europe. The discovery that 24-epibrassinolide was active in field tests and was more readily available from synthesis led to the compound becoming the focus of attention in laboratory and field experiments. Consequently, 24-epibrassinolide and brassinolide were examined as fungal hormones, to produce fruiting bodies, as antiecdysis compounds in insects and especially as yield enhancers in field and horticultural crops. By 1994 it is projected that Japan will have treated more than 23,000 hectares of wheat in China where yields, so far, have been increased 8-15%.

These components affect tobacco aphids, Myzus nicotianae Blackman, in several ways, including influencing the acceptance or rejection of plants for colonization by alate migrant aphids, and the survival and fecundity of alate and apterous aphids. Cuticular diterpenes and sucrose esters were isolated from the cuticular extracts of aphid resistant and susceptible N. tabacum genotypes. These compounds were applied topically to the backs of apterous aphids. LC(50)'s (dose per aphid which kills 50% of the test population after 48 hrs.) of the isolates were; alpha- and beta-4,8,13-duvatriene-1,3-diols, 15.7 mu g; alpha- and beta-4,8,13-duvatrien-1-ols, 6.4 mu g; cis-abienol, 7.5 mu g; sucrose esters (6-O-acetyl-3,3,4-tri-O-acylsucrose with C3 to C7 acyl groups), 0.25 mu g; and cis-abienol plus alpha- and beta-4,8,13-duvatrien-1-ols (1:3), 6.0 mu g.

Development of chemical pesticides is expensive, and will become more restricted as environmental concerns are recognized. Natural products, specifically peptides and neuropeptides, offer vast potential for exploitation as leads to pest control agents. Benefits from research into biologically active peptides and related factors include the necessity to investigate and understand, in detail, the physiological context in which the peptide operates. In addition, research on peptide biosynthesis, mode of action, and catabolism reveals numerous biochemical steps which may prove to be targets for control agents. The variety of candidates for naturally-based control agent development is extensive, including microbial iron binding systems, fungal toxins, arthropod venom components, insect immune peptides, neuropeptides and others. In this symposium, these endogenous molecules are discussed with regard to the physiological processes they regulate and potential consequences of their manipulation, the need to explore leads to control agents in a wide variety of organisms, and the need to examine emerging technologies in an effort to bring laboratory successes to the field.

The major impediment to the development of tentoxin as a herbicide is its limited availability because of low biosynthetic yields. Iturins are a family of cyclic octapeptides having a unique beta-amino acid, iturinic acid, incorporated into the peptide backbone. Iturins have a broad antifungal activity, but low biosynthetic yields may limit their commercialization. Chemical synthesis of both molecules is possible and the production of analogues has led to meaningful structure/activity relationships. To date no analog has provided greater activity or specificity than the parent molecule for either of the two agents. Molecular genetic manipulation is considered the best strategy for the increase in production of both of these compounds for cost effective synthesis. Success of cloning of the biosynthetic genes may determine the eventual deployment of these biorational pesticides. RP LAX, AR (reprint author), USDA ARS,SO REG RES CTR,NEW ORLEANS,LA 70179, USA.

Nearly 80 novel insect neuropeptides have been sequenced to date, 10 or so gene sequences have been determined, numerous analogs have been synthesized, and neuropeptide genes have been expressed in vector systems. Investigations into sites of synthesis and release, and tissue specificity and action, continue to reveal complexity in the (classically simple) insect neuroendocrine system. The rapidly increasing knowledge in this area suggests that useful prototypes for the design of selective pest control agents will emerge in the forseeable future.

They are found only in Arthropods; infecting the immature, feeding stage of the insect and causing devastating epizootics in natural populations. The range of susceptible insects is limited to closely related species, often only within the same genera. In addition, the infectious virion is embedded in a protein body that protects it from inactivation in storage and in the field. Increased levels of resistance to chemical insecticides, the public's concern with environmental contamination and the possible health effects of chemicals in their food, have focused attention on the use of alternative methods for pest management. The papers in this session review the current research on these viruses, including altering the viruses with recombinant DNA techniques to develop more effective pest management tools.

Their generally high degree of host specificity and ability to produce epizootics are among their most favorable attributes. The broader host ranges of a few NPVs offer hope for using a single virus to control several key pests and expands the potential market for these viruses. The rather rapid inactivation of NPVs by sunlight and the longer time required to kill pests, compared to chemical pesticides, are unfavorable attributes. In the future, the addition of feeding stimulants, UV protectants, and natural or chemical enhancers to increase infectivity of viruses may make viruses more competitive with chemicals for insect control.

Many natural products and biologically derived pest management agents differ significantly from conventional chemical pesticides in chemistry, complexity, and mode of action. However, such differences are difficult to categorize in terms of relative risk and few regulatory precedents exist. This has created difficulties for the regulatory community which makes the decision-making process sometimes appear unduly slow. Progress is being made as more biopesticides are registered and experience of their use has accumulated. C1 USDA ARS,BELTSVILLE,MD 20705.

These residues are efficiently packed to eliminate energetically unfavorable cavities. Contrary to these observations, high resolution X-ray crystallographic analyses of four homologous lipases from filamentous fungi reveal an alpha/beta fold which contains a buried conserved constellation of charged and polar side chains with associated cavities containing ordered water molecules.

'Grasslands Matua' was slower to emerge than both tall fescue and smooth brome grass, but by first harvest (52 days after sowing), prairie grass had longer tillers (51 versus 38 and 26 cm), a greater number of seed heads (15 versus 0.3 and 0.1), and a higher stem/ leaf ratio (0.95 versus 0.14 and 0.01) than smooth brome grass and tall fescue, respectively. There were no differences in 2-year mean tiller populations, leaf area, leaf yield, and stem yield between prairie grass and smooth brome grass at first harvest. Twenty days after sowing there were no differences in root length density among the three species. However, by first harvest, prairie grass at 20 cm depth had 135% of the root counts of the other two grasses. At 40 cm, prairie grass had 130 and 200% of the counts of smooth brome grass and tall fescue, respectively. The increased rooting of prairie grass was even more pronounced at the 80 cm depth where it had 160% of the smooth brome grass counts and 310% of the tall fescue root counts. Trend analysis resulted in linear, quadratic, and cubic responses for root growth with soil depth for smooth brome grass, tall fescue, and prairie grass, respectively.

A procedure for evaluating whether a given climate change scenario will speed up or slow down the seasonal decrease of snow covered area is outlined with hypothetical examples for a simple basin. This procedure has two main purposes. First, it can be used to generate snow covered area data in a new climate for input to runoff models such as the Snowmelt-Runoff Model (SRM). Second, it could potentially be used to provide input to climate models that require knowledge of the land area covered by snow at a given time. A computer program is now operational for use on real basins and is demonstrated on the Rio Grande basin in Colorado and the Illecillewaet River basin in British Columbia.

Cross-section regressions are run on social accounting matrix (SAM) multipliers and their decompositions obtained from a data set consisting of 27 SAMs. Agriculture's strong backward linkage to non-agriculture makes it a 'leading sector' in Hirschman's big-push industrialization strategy. The decompositions of these multipliers illuminate the crucial, indirect contributions made by household demands to agricultural production linkages. The potential of the linkages make ADLI an attractive policy alternative for countries at low levels of development. RP VOGEL, SJ (reprint author), USDA,ECON RES SERV,WASHINGTON,DC 20250, USA.

Whole, frozen flies were used for extraction with acidified methanol. A cockroach hindgut muscle contraction bioassay was used for monitoring fractions during subsequent purification steps. A series of eight different high performance liquid chromatography column systems was required to obtain optically pure peptides. Two peptides were isolated and their sequences determined by Edman degradation and confirmed by mass spectrometry and chemical synthesis as APTANGVR-NH2 and GLGNNANGVR-NH2. They were named callitachykinin I and II. The peptides have sequence similarities to the locustatachykinins and vertebrate tachykinins. Both callitachykinins were recognized by an antiserum to locustatachykinin I in enzyme-linked immunosorbent assay (ELISA) tests and callitachykinin II was additionally recognized by an antiserum to the Vertebrate tachykinin kassinin, suggesting that immunolabeling of blowfly neurons with these antisera is due to neuronal callitachykinins.

An air-assisted nozzle applied mixtures at 9.4 litre ha-1 spray rate with volume median diameters (VMD) of 96 and 337 mum, as verified with a Malvern laser diffraction analyzer. An hour after spraying, susceptible 3rd-instars walked for 2-min through wet droplets of spray mixtures applied at bifenthrin rates of 22, 45, 67, 90, and 112 g a.i. ha-1. Mortality was assessed at 21, 26, 45, 50, 74, and 117 h after exposure. Final mean mortality was affected (P = 0.01) by bifenthrin rate and droplet size. Bifenthrin applied in 337 mum VMD droplets caused 75.8%, mortality, whereas 96-mum VMD droplets resulted in a mortality of 67.9%. Also, the 337-mum VMD droplets killed larvae in 13% less time than the 96-mum VMD droplets, based on analysis (P = 0.01) using the mean elapsed time till death as the dependent factor.

Images were acquired with a multispectral video system, including three bandpass filters centered at 550, 800, and 1000 nm, from an altitude of 305 m. The ground-level dimension of the video image pixels was 0.329 m. Images were statistically analyzed with two supervised classification methods (minimum distance and maximum likelihood). The minimum-distance classifier yielded statistically similar results to the maximum likelihood classifier while requiring much less time. Multitemporal imagery increased classification accuracies on the order of 10 percent. Average classification accuracy for individual frees on all plots was 70 percent.

We measured leaf area and internode lengths and dry masses for 19 strains of Zea mays L., with mature leaf numbers ranging from 10 to 27, at a uniform population density. Similar measurements were made on plants growing in four different plant densities for one of the cultivars (Pioneer 3344). The number of the ear nodes correlated well with total leaf number. In general, area per ear-node leaf increased up to 20 total leaves, with considerable variability among strains having roughly the same total leaf number. Other general relationships were found between total leaf number and (a) the nodal position of the leaf with maximum area, as well as (b) the two positions above and below the ear node for 1/2 maximum area, (c) internode lengths, and (d) internode dry masses. Such information can be used for developing better maize production management models, as well as better selection methods for increased productivity.

Ruby Red) flavedo, albedo, and juice vesicles harvested at five periods throughout the season. Flavedo beta-galactosidase activity was high at the September harvest and then significantly declined by November. Thereafter, no further changes occurred in beta-galactosidase activity. Flavedo alpha-galactosidase activity was low and unchanged throughout the study. Alpha-mannosidase, initially low in flavedo, steadily increased with advanced maturity. Trends in glycosidase activities of albedo were similar but attenuated. Juice vesicle beta-galactosidase did not change through the study period, whereas alpha-galactosidase activity decreased 70% after the initial harvest period. Alpha-mannosidase was initially high and then decreased to 50% of the original activity. A second peak of activity was measured in March, followed by a second decline. Extractability differences of the glycosidases suggest differences in compartmentation and function. Two isozymes of alpha-mannosidase were separated in flavedo and one in juice vesicles. and characteristics were determined at an early and late harvest period. The results suggest that changes in the three glycosidases could be used to further define maturity and senescence in grapefruit. C1 USDA,US CITRUS & SUBTROP PROD LAB,WINTER HAVEN,FL 33883.

Arc) and orchard grass (Dactylus glomerata L. cv. Potomac), were grown at ambient (367 mumol mol-1) and elevated (729 mumol mol-1) CO2 concentrations at constant temperatures of 15, 20, 25 and 30-degrees-C in order to examine direct and indirect changes in nighttime CO2 efflux rate (respiration) of single leaves. Direct (biochemical) effects of CO2 on nighttime respiration were determined for each growth condition by brief (<30 min) exposure to each CO2 concentration. If no direct inhibition of respiration was observed, then long-term reductions in CO2 efflux between CO2 treatments were presumed to be due to indirect inhibition, probably related to long-term changes in leaf composition. By this criterion, indirect effects of CO2 on leaf respiration were observed at 15 and 20-degrees-C for M. sativa on a weight basis, but not on a leaf area or protein basis. Direct effects however, were observed at 15, 20 and 25-degrees-C in D. glomerata; therefore the observed reductions in respiration for leaves grown and measured at elevated relative to ambient CO2 concentrations could not be distinguished as indirect inhibition. No inhibition of respiration at elevated CO2 was observed at the highest growth temperature (30-degrees-C) in either species. CO2 efflux increased with measurement and growth temperature for M. sativa at both CO2 concentrations; however, CO2 efflux in D. glomerata showed complete acclimation to growth temperature. Stimulation of leaf area and weight by elevated CO2 levels declined with growth temperature in both species. Data from the present study suggest that both direct and indirect inhibition of respiration are possible with future increases in atmospheric CO2, and that the degree of each type of respiratory inhibition is a function of growth temperature.

Rutgers) at 1 and 10 ng (g fresh weight)-1, respectively (Priem and Gross 1992 Plant Physiol. 98: 399-401). Also, the occurrence and structure of 10 unconjugated N-glycans, including Man5GlcNAc. in tomato fruit were recently reported (Priem et al. 1993, Plant Physiol. 102: 445-458). In this work, we studied the potential interaction between Man5GlcNAc and several compounds by using a system that allowed pericarp discs to be kept up to 14 days after excision. Studies were performed to determine the effect of Man5GlcNAc, indole-3-acetic acid (IAA). concanavalin A and tomato lectin on ripening as defined by red coloration of the skin. Ripening in pericarp discs. unlike that in intact fruit. was unaffected by 1 ng (g fresh weight)-1 Man5GlcNAc. However, discs showed delayed ripening with 10 ng (g fresh weight)-1, and the delay of coloration was galactose dependent. Man5GlcNAc at 10 na (g fresh weight)-1 inhibited the stimulation of coloration induced by 100 muM IAA in the presence of 40 mug (g fresh weight)-1 galactose. Man5GlcNAc lost biological activity in the presence of the two lectins. These results support the possible interaction of IAA and various oligosaccharides during plant growth and development, and for the first time suggest a physiological significance for tomato lectin.

In this review we discuss this rapidly expanding field of study and propose that both increasing and decreasing rates of leaf and whole-plant respiration are likely to occur in response to rising CO2 concentrations. While the stimulatory effects of CO2 on respiration are consistent with our knowledge of leaf carbohydrate status and plant metabolism, we wish to emphasize the rather surprising short-term inhibition of leaf respiration by elevated CO2 and the reported effects of long-term CO2 exposure on growth and maintenance respiration. As is being found in many studies, it is easier to document the respiratory response of higher plants to elevated CO2 than it is to assign a mechanistic basis for the observed effects. Despite this gap in our understanding of how respiration is affected by CO2 enrichment, data are sufficient to suggest that changes in leaf and whole-plant respiration may be important considerations in the carbon dynamics of terrestrial ecosystems as global CO2 continues to rise. Suggestions for future research that would enable these and other effects of CO2 on respiration to be unravelled are presented.

The latter rutinoside of catechin is especially interesting because of the exceptionally small J(2,3) C-ring coupling. The glucoside of catechin-(4 alpha-->8)-catechin is only the second proanthocyanidin found in nature in which a 3-O-glycoside is present in the upper 'extender unit' of a dimer.

Of eight enzyme systems studied in detail, only one, phosphogluconate dehydrogenase, was monomorphic. Diaphorase, malate dehydrogenase, glutamate oxaloacetate transaminase, and esterase were highly polymorphic in race 0, whereas isozyme variation in races 2 and 3 was very limited. Race 0 accordingly had a significantly higher average gene diversity than did race 2 or race 3. Genetic similarity between races 2 and 3 was very high. Their allele frequencies differed clearly at only two putative esterase loci. Races 2 and 3 were only distantly related to race 0, as demonstrated by cluster analysis and principal coordinates analysis. There was no apparent genetic variation among five race 1 isolates from North Carolina and South Carolina. Their common electrophoretic type occurred also in race 2 but not in race 0 or race 3, suggesting a common ancestry with race 2. Only a small proportion of race 2 and race 3 isolates or race 2 and race 0 isolates shared common electrophoretic types, which suggests that there is little, if any, genetic exchange between these races.

Segregations at single loci also were observed for three isozyme systems and for one of two bands in a fourth system. Progeny also segregated for four esterase bands, but the segregation patterns were complex. Pathogenicity to corn was inherited as two apparently complementary genes present in race 2 but lacking in race 0, which was avirulent on corn. Evidence was found for a new locus for production of pseudothecia and a new locus for production of asci and ascospores. These putative loci differ from the previously described single loci for pseudothecium and ascospore production in C. carbonum. Gene mapping analysis identified two linkage groups: one 11 cM (centiMorgans) long with two linked loci for esterase bands, and one 164 cM long with six loci including the mating type locus, one locus for cadmium tolerance, and two loci for esterase bands. A quantitative trait locus for conidium production was found within 2 cM of the Est-B92 locus of the larger linkage group. The frequency distributions among race 0 X race 2 progeny for the numbers of conidia and pseudothecia produced were skewed toward poor production by most of the progeny relative to the parents.

This protein sequence has significant similarity to a sorghum glycine-rich protein [S1, Cretin and Puigdomenech (1990) Plant Mol. Biol. 15: 7831 and a maize embryo, abscisic acid-induced glycine-rich protein [Gomez et al. (1988) Nature 334: 262]. Tissue printing was used to localize the glycine-rich protein transcript in tomato fruit, stem and hypocotyl sections. The transcript is present throughout the tomato fruit pericarp but is enriched in the vascular bundles. In tomato hypocotyl tissue prints, the glycine-rich protein transcript as well as rRNA were localized within the vascular tissue. This shows that differential loading of RNA may occur when using the tissue printing technique on hypocotyl sections. Direct isolation and comparison of RNA from vascular-containing and non-vascular stem tissue confirmed, however, that the glycine-rich protein transcript is accumulated abundantly in the vascular tissue of tomato stem.

Based upon the literature, it was hypothesized that both elevated CO2 and N would cause increased foot biomass which would in turn cause increases in both total soil CO2 efflux and microbial respiration. This hypothesis was only supported in part: both CO2 and N treatments caused significant increases in root biomass, soil pCO(2), and calculated CO2 efflux, but there were no differences in soil microbial respiration measured in the laboratory. Both correlative and quantitative comparisons of CO2 efflux rates indicated that microbial respiration contributes little to total soil CO2 efflux in the field. Measurements of soil pCO(2) and calculated CO2 efflux provided inexpensive, non-invasive, and relatively sensitive indices of belowground response to CO2 and N treatments.

Once established, plants were deficit irrigated; growth chamber conditions were maintained at day/night temperatures of 25/16 degrees C, relative humidities of 35%/90% and a 14-hour photoperiod to simulate summer conditions on the shortgrass steppe in eastern Colorado. After 11 weeks of growth, plants grown under CO2 enrichment had produced 35% and 65% greater total and root biomass, respectively, and had twice the level of vesicular-arbuscular mycorrhizal (VAM) infection (19.8% versus 10.8%) as plants grown under current ambient [CO2]. The CO2-enriched plants also exhibited greater leaf water potentials and higher plant water use efficiencies. Plant N uptake was reduced by CO2 enrichment, while P uptake appeared little influenced by CO2 regime. Under the conditions of the experiment, CO2 enrichment increased root biomass and VAM infection via stimulated growth and adjustments in C partitioning below-ground.

These forests grow under contrasting rainfall regimes: Maricao is a wet forest located at altitudes above 500 m and receiving more than 2500 mm rainfall, while Susua is a humid forest located well below 500 m, with less than 1500 mm rainfall and a well defined dry season. Dominant tree species and soils were analysed for N, P, K, Ca, Mg and Ni. Soils can be differentiated according to their K content (higher in Maricao) and P contents (higher in Susua). Mature leaves of both forests have sclerophyllous characteristics as judged from the Specific Leaf Areas (<80 cm(2) g(-1)) and low P contents. Leaf area development is strongly correlated with leaf N and P contents in both forests, but Maricao samples appear to be more limited by P availability, In concordance with soil values, the Susua leaf sample set has significantly higher contents of P, but lower contents of K when compared with the Maricao sample set. Analyses of soluble K, Ca, and Mg reveal strong physiological selectivity in the absorption of these cations. K/Ca and Ca/Mg ratios are markedly higher in the soluble leaf extracts than in the soil extracts. It seems that restriction to vegetation development in the serpentine areas investigated are more related to nutritional deficiencies and not to high contents of either Mg or Ni in the upper soil layers. Only two strong Ni accumulators were found, Cassine xylocarpa (1.2 mu mol Ni g(-1) dry mass or 70 mu g g(-1)) from Susua, and Chionanthus domingensis (12.2 mu mol g(-1), or about 700 mu g g(-1)) from Maricao. These species are not restricted to serpentine areas in Puerto Rico. C1 US FOREST SERV,INT INST TROP FORESTRY,RIO PIEDRAS,PR 00928.

Considerable effort has been directed towards identifying 'nutrient efficient' species and germplasms, but the many different definitions for efficiency make the use of the term ambiguous. The concept of nutrient efficiency was evaluated using data from a study of differences in germplasm response to phosphorus (P) availability in white clover (Trifolium repens L.) and alfalfa (Medicago sativa L.) grown in a sand-alumina culture. Application of various criteria identified in the literature as measures of nutrient efficiency did not clarify differences between purportedly P efficient and inefficient germplasms. Germplasms differed in maximum shoot and total dry mass and in solution P concentration required to achieve 80% maximum yield, but not in tissue P concentration, internal P utilization, or P uptake per unit of fine root dry mass. Differences may have resulted from factors other than efficient use of available P. To reduce the confounding effects that other factors have on nutrient efficiency, we propose that equivalent yields of germplasms be demonstrated where nutrients are not limiting. Mechanisms that enable enhanced nutrient efficiency can be identified less ambiguously using this improved approach. C1 UNIV MINNESOTA,DEPT SOIL SCI,ST PAUL,MN 55108.

The Rj4 gene conditions ineffective nodulation primarily with certain strains of the slow-growing soybean microsymbiont, Bradyrhizobium elkanii. The F2 seeds of the cross of the cultivars Peking, carrying the alleles rfg1, Rj4, i (controlling inhibition of seed coat color) and W1 (controlling flower color), and Kent, carrying the alleles Rfg1, rj4, i-i and w1, were evaluated for nodulation response with strain USDA 205 by planting surface disinfested seeds in sterilized vermiculite in growth trays and inoculating with a stationary phase broth culture of strain USDA 205 at planting. Plants were classified for nodulation response visually after four weeks growth and transplanted to the field for F3 seed production. Flower color, purple (W1) vs white (w1), was determined in the held. The allele present at the i locus was determined by classification of F3 seed coat color. The F3 seeds were planted in growth trays and inoculated with strain USDA 61 of Bradyrhizobium elkanii to determine the genotype for the Rj4 locus. The Rfg1 and Rj4 genes were determined to be located at separate loci. Chi-square analysis for linkage indicated that Rfg1 segregated independently of the Rj4, I and W1 loci.

Onozuka R-10 (2%) in combination with Macerase (0.5%) was found best for protoplast isolation and mediocre for cell isolation among several enzyme combinations tested. Viability was 90% for protoplasts and 60% for cells. Pectolyase Y23 was found to be ineffective in our investigation. Small leaves, 4-10 mm in length, were a1 superior source for protoplast isolation than medium or big expanded leaves, 22-30 mm in length. The high yields of protoplasts could be obtained only when keeping the ratio of leaf biomass to volume of digesting enzyme solution under 20 mg ml-1. Purification of protoplasts on a1 sucrose gradient yielded about 10(7) protoplasts . gfw-1, however, the preparation was still contaminated by intact cells. Protoplasts were cultured under different growth regulators and physical conditions. Limited growth and division of protoplasts embedded in agarose drops were observed.

The plants were ranked for resistance based on measurements in 12 replications, and the five most resistant and the five most susceptible (selection pressure of 20%) plants in each population were identified. Subsets consisting of 11, 9, 7, and 5 replicates were systematically or randomly selected by a computer program from the original 12 replicates, and the plants were ranked again and selected for resistance. The probability of reselecting plants previously identified as either one of the five most susceptible or resistant plants in each population was determined for each size subset. With five replicated inoculations, there was an 83% probability of reselecting three to five of the most resistant or most susceptible plants, and a 55% probability of reselecting four or five of the most resistant or susceptible plants. These results indicated that at least five replicated measurements of each plant with the stem inoculation method are needed for selection of resistance to S. trifoliorum.

Foliage symptoms, stunting, and significant yield reductions due to BPMV occurred in all but one of the 12 soybean entries. Pod infection was consistently increased by BPMV, whereas seed infection was significantly increased in genotypes only if the virus infection delayed the rate of seed maturation. BPMV delayed maturity by extending the length of late-season growth stage intervals and increased seed infection in the soybean entries susceptible or moderately resistant to seed diseases. Effects of BPMV on soybean genotypes that matured under the same environmental conditions indicate that initial levels of seed infection are directly related to the rate of pod and seed maturation. Modifications by BPMV in the R7-R8 interval that delayed harvest maturity of soybean entries susceptible and moderately resistant to seed infection were correlated with increases in levels of seedborne Phomopsis spp. C1 PURDUE UNIV,DEPT BOT & PLANT PATHOL,W LAFAYETTE,IN 47907.

The virus was sap-transmissible to species of Amaranthaceae, Chenopodiaceae, Cucurbitaceae, Leguminosae, and Solanaceae. Chenopodium amaranticolor was used as a local lesion assay host and Pisum sativum cv. Little Marvel, as the propagation host for purification. The virus was nonpersistently transmitted by Aphis craccivora and Myzus persicae but was not transmitted through the seed of sesame. The virus remained infective in buffered leaf sap of Nicotiana benthamiana at a dilution of 10(-5) after storage for 9 days at 25 C and heating for 10 min to 55 C (but not to 60 C). The virus induced cylindrical cytoplasmic inclusions in infected tissues of Lupinus albus. Purified virus preparations yielded flexuous filamentous particles that contained a major polypeptide of approximately 33 kDa and one nucleic acid species with molecular weight of 3.1 X 10(6). In indirect enzyme-linked immunosorbent assay, the virus reacted positively to antisera of blackeye cowpea mosaic, peanut green mosaic, peanut stripe, pea seedborne mosaic, soybean mosaic, tobacco etch, watermelon mosaic virus 2, and zucchini yellow mosaic viruses but not to watermelon mosaic virus 1 and peanut mottle and bean common mosaic viruses. In reciprocal tests, peanut stripe virus and watermelon mosaic virus 2, but not peanut green mosaic, peanut mottle, pea seedborne mosaic, blackeye cowpea mosaic, soybean mosaic, and tobacco etch viruses, reacted with the antiserum for the sesame virus. On the basis of these properties, the causal virus is identified as an unnamed potyvirus isolate causing sesame mosaic. C1 UNIV GEORGIA,GEORGIA EXPT STN,DEPT PLANT PATHOL,GRIFFIN,GA 30223.

The products are called OATRIM and can lower blood cholesterol by replacing animal fats rich in cholesterol in food products and, possibly, by the action of beta-glucan in the body after consumption. In the chick model, decreased total blood cholesterol also resulted in increases of HDL cholesterol and decreases of LDL cholesterol. Processing conditions were found that gave the maximum amount of beta-glucan and desirable fat-replacement qualities with the least amount of color and flavor.

Chimeric genes containing the ubi3 promoter (920 bp of 5' to the ubiquitin start codon) were constructed in which the reporter gene beta-glucuronidase (GUS) was either fused directly to the promoter, or introduced as a translational fusion to the ubiquitin-coding region. After introduction into the potato by Agrobacterium-mediated transformation, GUS activities were measured in leaves and in tubers of transgenic clones. GUS activity was 5- to 10-fold higher in clones expressing the ubiquitin-GUS translational fusion than in clones containing GUS fused directly to the ubi3 promoter. For both types of constructs, GUS activity was highest in meristematic leaves and declined during leaf expansion, then rose again to near the meristematic levels during senescence. GUS activity in tubers was similar to that in young leaves. In contrast to the native ubi3 genes, the chimeric ubi3-GUS transgenes were not activated in the tuber by wounding.

Immature zygotic embryos, young callus, and microspore-derived embryos were bombarded with a plasmid containing bar and uidA either alone or in combination with another plasmid containing a barley yellow dwarf virus coat protein (BYDVcp) gene. A total of 91 independent bialaphos-resistant callus lines expressed functional phosphinothricin acetyltransferase, the product of bar. Integration of bar was confirmed by DNA hybridization in the 67 lines analyzed. Cotransformation frequencies of 84 and 85% were determined for the two linked genes (bar and uidA) and for two unlinked genes (bar and the BYDVcp gene), respectively. More than 500 green, fertile, transgenic plants were regenerated from 36 transformed callus lines on bialaphos-containing medium; albino plants only were regenerated from 41 lines. T-0 plants in 25 lines (three plants per line) were analyzed by DNA hybridization, and all contained bar. Most contained the same integration patterns for the introduced genes (bar, uidA, and the BYDVcp gene) as their parental callus lines. Transmission of the genes to T-1 progeny was confirmed in the five families analyzed by DNA hybridization. A germination test of immature T-1 embryos on bialaphos-containing medium was useful for selecting individuals that were actively expressing bar, although this was not a good indicator of the presence or absence of bar. Expression of bar in some progeny plants was indicated by resistance to the herbicide pasta. The T-1 plants were in soil approximately 7 months after bombardment of the immature embryo.

The methods were destructive in that the root must be excised from the shoot but do not require removal of the root from the soil. The methods involve pushing water from the excised base of the root to the apex, causing flow in a direction opposite to that during normal transpiration. Sample data are given for two tropical (Cecropia obtusifolia and Lacistema aggregatum) and two temperature species (Acer saccharum and Juglans regia cv Lara). A hysteresis was observed in the relationship between applied pressure and resulting flow during dynamic measurements. A mathematical model (AMAIZED) was derived for the dynamics of solute and water flow in roots. The model was used to interpret results obtained from steady-state and dynamic measurements. AMAIZED is mathematically identical with the equations that describe Munch pressure flow of solute and water in the phloem of leaves. Results are discussed in terms of the predictions of AMAIZED, and suggestions for the improvement of methods are made. C1 UNIV VERMONT,DEPT BOT,BURLINGTON,VT 05405.

Fluorescamine labelling of KI-washed microsomes inhibited both ATP hydrolysis and coupled proton pumping. However, ATP hydrolysis was considerably less sensitive than proton pumping to the treatment. The inhibition and labeling of membrane phosphatidylethanolamine appeared to exhibit a similar dependence to fluorescamine concentration, suggesting that labeled phospholipids were involved in the inhibition. Fluorescamine was allowed to react with benzylamine, butylamine and phenylalanine to form non-reactive acyclic and cyclic derivatives. The addition of preformed acyclic derivatives also caused a differential inhibition to coupled activities of vanadate-sensitive H-ATPase in KI-washed microsomal vesicles, isolated plasma membrane, and reconstituted microsomal and plasma membrane vesicles. However, the cyclic form of the derivatives was found to have no effect on coupled activities. The observed differential inhibition supports the presence of an indirect coupling between the functions of proton pumping and ATP hydrolysis of com root vanadate-sensitive H+-ATPase. The observed difference between acyclic and cyclic forms of the derivatives also suggests that the coupling arrangement of the H+-ATPase is sensitive to the presence of a derivatized fluorescamine structure capable of forming multiple hydrogen bonds.

Batsch) leaves were found to tolerate relatively high levels of the bacteriocidal polypeptide cecropin B as determined by infiltration tests. Detached leaves showed no symptoms when infiltrated with 25 mu M cecropin B, and only infrequent necrotic symptoms with 50 mu M. Incubation of cecropin B with intercellular fluid (ICF) extracted from peach leaves reduced its biotoxicity toward the peach pathogen Pseudomonas syringae pv. syringae. The reduction in toxicity was lessened by adding proteinase inhibitors to ICF - and prevented by boiling ICF prior to incubation with cecropin B. Electrophoretic evidence suggested that ICF constituents caused endopeptidase cleavage of cecropin during the first hour of incubation followed by complete digestion of the cleavage products during the following 8 h. Incubations of various levels of cecropin B and ICF indicated that as much as 90% of the activity could be destroyed in 10 min, but that levels adequate for lethality against P. syringae pv. syringae would remain. We conclude that peach trees transgenic for cecropin B could feasibly produce a wide range of cecropin levels sufficient to control pathogenic bacteria without damaging the leaf tissue.

The procedure employs the electroporation of germinating pollen in the presence of foreign DNA using an exponential discharge pulse. When the pollen tube membrane is permeabilized by the electroporation pulse, it allows the influx of DNA that has been added to the electroporation medium. Species-specific modifications of the electroporation medium maintain the viability of germinating pollen while optimizing the DNA uptake. Transient assays of CAT and GUS expression in pollen were used to monitor changes in uptake of DNA to optimize DNA expression by electroporated pollen. One DNA construct, pLAT52-7, contained a pollen-specific promoter, which enhanced GUS expression in pollen as compared with experiments using pBI22I plasmid with the CaMV 35S constitutive promoter. Production of transformed plants by pollination with electroporated pollen was confirmed by genomic DNA Southern hybridization, PCR amplification and hybridization, fluorometric GUS assays, and tissue level histological localization of GUS expression. The introduction of genetic material into the pollen and the production of transformed plants produced from seed formed after fertilization with treated pollen could have a tremendous impact on the improvement of economically important crops.

The plasma membrane was isolated from mature and young leaves of untreated (control) and salt-stressed leaves using the aqueous polymer two-phase technique. Analysis of ATP hydrolytic activity showed that salt stress reduced the V-max of H+-ATPase specific activity in mature leaves but had no effect in young, growing leaves. These findings are consistent with measurements of adenine nucleotide levels. We observed a large decrease in adenylate energy charge (AEC) in mature leaves following salt stress. AEC in young leaves remained unaffected. In addition, a dramatic increase in K, the adenylate kinase mass action ratio, from 0.18 to 1.53 was measured in mature leaves following salt stress. These results indicate-that salt stress did not reduce growth of young, growing leaves by decreasing H+-ATPase activity and support our earlier hypothesis that salt stress affects mature leaves and, as a consequence, their ability to supply essential metabolites for growing regions of both shoot and roots.

These include the number of bells on a fruiting branch, and on a secondary level, the location of seeds within a locule. Cotton ovule culture was employed to assess the contribution of competition for resources to fiber quality. Elongation and secondary wall deposition were compared in plant-grown and culture-grown fibers. In plant-grown material, seeds located in the middle of a locule had the longest fibers. Fiber length distributions were similar for ovules taken from the apical, medial and basal locations in a locule and grown in ovule culture. Secondary wall deposition was greatest in fibers located on basal seeds or ovules. On a single seed or ovule, fibers in the micropylar region had thicker cell walls than in the chalazal region. Competition for resources has been eliminated in vitro and the same pattern of secondary wall deposition occurred in the micropylar and chalazal regions of seeds and ovules. Therefore, conditions present at the time of ovule excision influenced secondary wall deposition. One condition may be fiber diameter.

To facilitate the analysis of promoter regions from these genes, a transient assay was established using protoplasts from a maize (Zea mays L.) endosperm suspension culture. The activities of several different promoters in transcriptional fusions with the chloramphenicol acetyl transferase (CAT) reporter gene were compared. The maize alcohol dehydrogenase I (Adhl) promoter/intron was the most active tested, nearly 2000-times background; the cauliflower mosaic virus (CaMV) 35S promoter was about 270-times background. Use of an endpoint assay for CAT enzyme activity allowed detection of the lower activities of the promoter regions of the maize Shrunken (Sh) (8.4-times background) and Agrobacterium nopaline synthase (Nos) (3.9-times background) genes, and of a wheat alpha-gliadin gene (4.4-times background). Promoters from another family of wheat seed storage protein genes, the high molecular weight (HMW) glutenin subunits, were also active, at levels between 10- and 60-times background. This is the first report of activity from wheat seed storage protein gene promoters in a monocot transient assay. There were no statistically significant differences in activity among four different length versions of the Dy10 glutenin promoter ranging in size from 2800 to 307 bp, or between similar versions of the Dy10 and Dx5 glutenin gene promoters. These results show that maize endosperm suspension cells provide a readily available source of protoplasts for comparisons of cereal gene promoters that are active in developing endosperm tissue.

Plasmid DNA (pBI-121) containing the gus A gene under control of the cauliflower mosaic virus 35S promoter was used. One-month-old protocorms were selected for DNA treatment just prior to the formation of their first true leaf. The DNA was suspended in agarose and placed in the tip of a pipette. The pipette was then placed over the protocorm's shoot tip and subjected to electrophoresis under various conditions. Introduction of DNA leading to stable transformation occurred at 0.5 mA constant current after 10 min of electrophoresis. Under these conditions, approximately 45% of the protocorms were alive one month after treatment. One year after electrophoresis, the marker gene was still expressed in leaves from approximately 55% of the surviving seedlings. Transformation was confirmed through polymerase chain reaction (PCR) analysis.

The concentration of 65, 60, and 14 kDa polypeptides increased in response to chilling under field conditions and with storage at 4-7 degrees C. Levels of the polypeptides increased most dramatically during the first 300 h of chilling and decreased to the initial levels with the resumption of growth. The pIs, determined by isoelectric focusing of bud proteins, were 7.5-8.0 for the 65 and 60 kDa polypeptides and 8.5 for the 14 kDa polypeptide. Purification of the 65 and 60 kDa polypeptides followed by amino acid sequence analysis of selected peptide fragments revealed similarities in amino acid composition between these polypeptides and dehydrins. Antiserum, raised against the lysine rich consensus sequence EKKGIMDKIKEKLPG of dehydrins, crossreacted to all three of the chilling-responsive polypeptides of blueberry. Thus, the accumulation of dehydrin-like proteins in response to chilling was demonstrated in a woody perennial. C1 USDA ARS,BELTSVILLE AGR RES CTR W,INST PLANT SCI,FRUIT LAB,BELTSVILLE,MD 20705.

Integrated functioning of both cytosolic and organelle-associated enzymes is required to link N assimilation with C metabolism. Understanding how N and C metabolism are controlled in root nodules requires fundamental knowledge of how the plant genes involved are regulated. While significant progress has been made in understanding the regulation of glutamine synthetase (GS), much less is known about the genes controlling other enzymatic steps in this process. To that end we have isolated, purified and characterized the root nodules enzymes aspartate aminotransferase (AAT), phosphoenolpyruvate carboxylase (PEPC) and glutamate synthase (NADH-GOGAT). Moreover the cDNAs encoding these crucial enzymes were isolated and characterized. While the most prominent forms of GS associated with N assimilation in nodules are located in the cytosol, AAT and NADH-GOGAT appears to be organelle-associated. The deduced amino acid sequence suggested and immunogold labeling showed that nodule-enhanced AAT-2 is located in amyloplasts. Comparison of the deduced amino acid sequence of nodule-enhanced NADH-GOGAT to the N-terminal sequence of the processed protein indicated that NADH-GOGAT has a 101 amino acid presequence. However, it is unclear as to which organelle NADH-GOGAT is targeted. Cytosolic phosphoenolpyruvate carboxylase (PEPC), which can be expressed in legume root nodules at levels comparable to those detected in leaves of C4 plants, provides a substantial amount of carbon for malate, aspartate and asparagine biosyntheses. RNA blots showed that GS, AAT, PEPC, and NADH-GOGAT mRNAs were enhanced about 15-fold during the development of effective alfalfa nodules. By comparison, the expression of GS, AAT and PEPC mRNAs was reduced by 65% in ineffective nodules. NADH-GOGAT was different from GS, AAT, and PEPC in that expression had an absolute requirement for a factor(s) related to effective nodules. The data suggest that NADH-GOGAT plays a key role in regulating N assimilation. Moreover, plastids in nodules play a major role not only in C metabolism but also in N metabolism.

Plants expressing a single copy of the satellite are efficiently protected against CMV-1 infection since viral symptoms do not appear in the infected plants. Satellite perfect dimer-expressing plants are less efficiently protected at the first stages postinoculation than monomer-expressing ones, suggesting that RNA transcripts containing dimers are inefficiently recognized by the CMV replicative machinery. Tobacco plants expressing two different fragments of the same satellite molecule each containing an open reading frame (ORF) with in vitro coding capacity do not show any satellite RNA-related sequence amplification upon infection with CMV-1, but present a short delay of 1 or 2 days in the appearance of viral symptoms that is irrespective of the virus inoculum concentration.

This paper compares the progress realized from bidirectional selection programs for P-efficiency (PE) and P-inefficiency (PI) and for screening techniques. Populations were evaluated both as whole plants in hydroponics and as callus tissue cultures at high (322.9 mu M) and low (8.1 mu M) P levels, with either fixed or inorganic nitrogen (N) sources. Hydroponically selected PE populations had greater shoot dry weights than PI populations when grown hydroponically with low P and inorganic N, but not with fixed N. The tissue culture selected PE population had a greater shoot dry weight than the PI population when grown hydroponically with low P and fixed N, but not with inorganic N. At high P, no yield differences were observed between populations. Root dry weights were not different between populations at either P level. No yield differences were detected between any selected population and the unselected parent, Rangelander, because selection progress per cycle of selection was small. PE and PI populations were not different when grown as callus tissue cultures with low P. Inbreeding depression appeared to reduce shoot yields and nodulation by Rhizobium meliloti of selected and control populations compared to Rangelander, Although progress was limited, bidirectional selection enabled us to detect significant yield differences between PE and PI populations developed using both screening techniques. If the paired populations resulting from bidirectional selection had not been developed, both screening methods would have appeared ineffective.

If 0.2% bovine serum albumin (BSA) is added to the medium, embedding substantially improves plating efficiencies of these protoplasts over unshaken liquid culture. This procedure allows regeneration of thousands of independent mutant or transformant cell lines with minimal chance of chimeras or multiple regenerants from one transformation event. Reproducible plating efficiencies of 8-20% were achieved under these conditions. A medium that increased the stability of isolated protoplasts also increased the absolute transformation efficiency obtained with polyethylene glycol (PEG)-mediated transformation by over 40%. Thus, the protoplast culture and transformation system described here constitutes a very efficient system for the generation of large numbers of independently transformed callus lines and is suitable for large scale insertion mutagenesis experiments based on transformation of haploid protoplasts.

Nitroso-reactive materials were present in petioles and around mature crown cavities of healthy plants. They were absent from tap roots, except that they occasionally were observed in lateral root tissue contained within tap roots. Nitroso-reactive materials were localized in healthy tissues surrounding quiescent, but previously active rot lesions caused by R. solani, but were not found around actively developing lesions or in association with wounds. The intensity of staining diminished late in the growing season. Preformed phenolic compounds may be involved in prophylaxis against pathogens in petioles and crown cavities and in active resistance against R. solani in sugar beet tap roots.

The fluorescence emission from leaf spot-sensitive and tolerant muskmelon mesophyll cells was not affected by roridin E. However, suspension cells from only the leaf spot-sensitive cultivar Iroquois exhibited a significant increase in fluorescence after 5 min of exposure to 10 mu M roridin E. These results suggest that roridin E may be a good in vitro selective agent for muskmelon suspension cells and that fluorescence measurements may be useful in screening muskmelon germplasm for resistance to M. roridum.

Plants were grown at 21 degrees C in a controlled environment chamber (500 mu mol photons m(-2) s(-1)). Thylakoid membranes were isolated from vegetative and flag leaves and analyzed for uncoupled electron transport activity. Significant genetic variability in chloroplast electron transport was found with fourfold differences in activity observed in the genotypes tested. Quantitative measurements were made for each component of the chloroplast electron transport chain, including the development of an immunochemical assay for plastocyanin. The genetic differences in electron transport activity were related to the concentration of plastocyanin in the thylakoid membrane. The fivefold differences in plastocyanin content observed within the genotypes tested corresponded to a plastocyanin pool size of 0.8-3.8 mol of plastocyanin per mol of photosystem I reaction center. Therefore, plastocyanin was a significant limiting factor in barley genotypes expressing low photosynthetic electron transport activity. C1 N CAROLINA STATE UNIV,USDA ARS,DEPT BOT,RALEIGH,NC 27695.

Developing resistant clones through breeding is the best long-term strategy to minimize tree damage caused by this disease. Tissue culture and somaclonal selection techniques may reduce the time needed to develop disease resistance in poplars. We used a single source clone of a hybrid Populus to determine the influences of explant tissue source and regeneration method on the frequency of somatic variation in disease resistance. Plants were regenerated adventitiously via shoots and somatic embryos from callus derived from several tissue sources and from axillary buds. The resulting plants expressed somatic variation in disease resistance in different frequencies, except for the plants regenerated from hardwood cuttings. Several regenerated plants from various tissue sources exhibited variant morphological phenotypes, providing further evidence of the instability of this clone when cultured in vitro. Although mutagenic effects of the culture regimes alone cannot be ruled out, results of this study suggest that the explant source and culture method influenced how frequently variant plants were recovered.

One of these genes, cryIA (c), was used to transform walnut somatic embryos using a binary vector (pWB139) in which this gene was expressed as a protein fusion with the kanamycin resistance gene from bacteria. Transgenic embryos representing individual transformation events were germinated to produce shoots that were maintained as micropropagated shoot lines in the laboratory. Transgenic shoots were then grafted onto seedling rootstocks and transplanted into the field. DNA analysis (Southern blotting) demonstrated that these shoots were transformed by pWB139 or by the control construct pWB149 (which does not contain the cryIA (c) gene). Insect feeding trials of walnut embryos grown in vitro and infested with neonatal Indianmeal moth, codling moth or navel orangeworm larvae showed non-significant mortality; confirming insufficient or incomplete expression of ICPs in the transgenic embryos. Therefore, transformation of somatic walnut embryos with the vector pWB139 was ineffective in protecting the embryos from damage by lepidopteran insect larvae.

Root growth and Ca2+ uptake were measured in 5-d-old seedlings of wheat (Triticum aestivum L. Thell) during exposure to Al3+ in a low-Ca2+ basal medium, and to Al3+ in the presence of added cations. Uptake of Ca2+ in whole roots and translocation to the shoot were measured using Ca-45(2+), and localized measurements of net Ca2+ flux were also made at the root apex using the technique of microelectrode ion-flux estimation. Treatment with 2.64 muM AlCl3 in 226 muM CaCl2, at pH 4.5, severely inhibited root growth without affecting Ca2+ uptake. Addition of 30 mM Na+, 3 mM Mg2+ or 50 muM tris(ethylenediamine)cobalt(III) to this Al3+ treatment restored root growth but significantly reduced Ca2+ uptake measured over the entire root system and at the root apex. The Al3+ and Ca2+ concentrations were adjusted so that the activities of the Al3+ and Ca2+ ions were constant in all solutions (1.5 muM and 200 muM, respectively). Root growth can be severely inhibited by Al3+ concentrations that do not affect Ca2+ uptake, while the addition of ameliorating cations depresses Ca2+ uptake. These results argue against the hypothesis that Al3+ inhibits root growth by reducing Ca2+ uptake. C1 CORNELL UNIV,USDA ARS,US PLANT SOIL & NUTR LAB,ITHACA,NY 14853.

EVALUATING THE CA2+-DISPLACEMENT HYPOTHESIS SO PLANTA LA English DT Article DE ALUMINUM TOXICITY; CALCIUM DISPLACEMENT; ELECTRICAL POTENTIAL; ROOT; TRITICUM ID DIVALENT-CATIONS; MEMBRANES; CELLS; PHYTOTOXICITY; BINDING; STRESS; CA-2+ AB Several mineral rhizotoxicities, including those induced by Al3+, H+, and Na+, can be relieved by elevated Ca2+ in the rooting medium. This leads to the hypothesis that the toxic cations displace Ca2+ from transport channels or surface ligands that must be occupied by Ca2+ in order for root elongation to occur. In this study with wheat (Triticum aestivum. L.) seedlings, we have determined, in the case of Al3+, that (i) Ca2+, Mg2+, and Sr2+ are equally ameliorative, (ii) that root elongation does not increase as Ca2+ replaces Mg2+ or Sr2+ in the rooting media, and (iii) that rhizotoxicity is a function solely of Al3+ activity at the root-cell membrane surface as computed by a Gouy-Chapman-Stern model. The rhizotoxicity was indifferent to the computed membrane-surface Ca2+ activity. The rhizotoxicity induced by high levels of tris(ethylenediamine)cobaltic ion (TEC3+), in contrast to Al3+, was specifically relieved by Ca2+ at the membrane surface. The rhizotoxicity induced by H+ exhibited a weak specific response to Ca2+ at the membrane surface. We conclude that the Ca2+-displacement hypothesis fails in the case of Al3+ rhizotoxicity and that amelioration by cations (including monovalent cations) occurs because of decreased membrane-surface negativity and the consequent decrease in the membrane-surface activity of Al3+. However, TEC3+, but not Al3+, may be toxic because it inhibits Ca2+ uptake. The nature of the specific H+-Ca2+ interaction is uncertain.

The enzyme AAT may also be important in providing substrates for host-plant and bacteroid respiration. The enzyme occurs as two isoenzymes, AAT-1 and AAT-2, with AAT-1 more abundant in roots and AAT-2 predominant in root nodules. To further elucidate the role of AAT in root-nodule metabolism, subcellular fractionation and immunocytochemical methods were used to determine the intra- and intercellular localization of these two isozymes. Fractionation of nodule subcellular components showed that AAT-2 was localized in amyloplasts. Immunogold labelling with AAT-2 antibodies unequivocally confirmed this, showing that AAT-2 was localized in nodule amyloplasts and leaf chloroplasts. In root nodules, the density of immunogold labelling of infected cell plastids was almost four times that of uninfected cell plastids. The data suggest that aspartate biosynthesis in alfalfa root nodules occurs primarily in the plastids of infected cells. C1 UNIV MINNESOTA,USDA ARS,PLANT SCI RES UNIT,ST PAUL,MN 55108.

However, curing behaviour of the resin under various environmental conditions is not well known. A differential scanning calorimeter was employed to characterize the degree of resin cure in this study. Resin-impregnated glass cloth samples with varied moisture contents (0, 31, 71%) were exposed to an environment of controlled temperature (105, 115, 125, 140 degrees C) and relative humidity (41, 75, 90%) for a series of time periods (0-20 min). The samples were next conditioned to different levels of relative humidity (0, 64, 89%) before being sealed in d.s.c, capsules. The degree of cure of these partially cured samples was then determined by d.s.c. by measuring the residual heat of cure. The results show that the degree of resin cure increased with increasing precure temperature and time. The rate of cure increased for dry samples as precure humidity increased. However, the rate of cure decreased with an increase in the initial moisture content of samples when precured at 90% relative humidity. The effect of moisture put into a sample immediately before analysis by d.s.c, on the subsequent calculation of resin precure became less significant with increasing precure temperature and degree of resin cure.

An understanding of the theology of thermoplastic starch melts is needed in order to understand the effects of processing on structure/property relationships. This article discusses the effects of temperature, moisture content, molecular weight reduction (hydrolysis), and low molecular weight additives on the behavior of thermoplastic starch melts. Thermoplastic starch melts exhibit power law behavior. The melt viscosity decreases with increasing temperature, moisture content, and decreasing molecular weight. Low molecular weight additives also reduce the viscosity. Glycerol monostearate slightly increases the melt viscosity. This effect is attributed to the formation of helical inclusion complexes which are stable at the extrusion temperatures. The power law index and the rate of change in viscosity with temperature of thermoplastic starch melts are similar to those of synthetic polymers.

Environmental concerns and escalating landfill costs are becoming increasingly serious problems to the leather industry and alternative disposal methods are needed. We have developed a process in which this waste is first treated with alkali to extract a high molecular weight gelable collagen protein. The sludge that remains is further treated with enzymes to recover a lower molecular weight protein hydrolyzate and a recyclable chromium product. The recovered protein fractions, practically devoid of chromium, could be used in a wide range of products, including adhesives, cosmetics, films, animal feed and fertilizer. The isolated chromium can be chemically treated and recycled into the tanning process. RP TAYLOR, MM (reprint author), USDA ARS,EASTERN REG RES CTR,600 E MERMAID LANE,PHILADELPHIA,PA 19118, USA.

Chemicals used for this purpose are: delta-aminolevulinic acid (ALA, a porphyrin precursor); protoporphyrinogen oxidase (Protox) inhibitors; and modulators of the heme and chlorophyll biosynthetic pathways such as 2,2'-dipyridyl and phenanthroline. A wide array of Protox inhibitors (herbicides) are commercially available, while ALA-based applications are still in the experimental stage. Protox inhibitors cause the accumulation of protoporphyrin IX and other porphyrins in plants via a complex mechanism. No weeds have thus far evolved resistance to herbicides with this mechanism of action. However, some plant species have natural tolerance to such herbicides by a variety of mechanisms. Protox inhibitors are apparently ineffective on insects; however, ALA and modulators of the heme pathway have insecticidal activity. Porphyrinogenic compounds such as ALA have been used or patented for use in photodynamic therapy, and as herbicides. The commercialization of ALA-based photodynamic herbicides will depend, however, on the success of efforts directed at translating successful greenhouse applications to field use. Protox inhibitors have been patented as pharmaceutical for treatment of disorders of the heme pathway. Protox inhibitor herbicides have been found to cause accumulation of certain porphyrins in non-target animals, although porphyria has not been reported.

The most potent Protox inhibitors more closely mimic one half of the Protogen molecule. These compounds are all bicyclic, non-planar molecules, similar to one half of the Protogen tetrapyrrole macrocycle. Among diphenyl ether Protox inhibitors, molecular bulk and overall electrostatic potentials were most responsible for variations in herbicidal effects, although other factors such as lipophilicity were also important. From QSAR analyses of various classes of peroxidizing herbicides, it appears that Protox-inhibiting activity responds primarily to the substitutional modifications on the phenyl ring (p-nitrophenyl in diphenyl ethers). Furthermore, a substitution at the meta position on the p-chloro (phenopylate) or p-nitro (diphenyl ether) ring is essential for greatest herbicidal activity.

The ability of these modulators to induce the accumulation of large amounts of porphyrins viz., protoporphyrin IX (Proto), magnesium-Proto and magnesium-Proto monomethylester (MPE), and protochlorophyllide (Pchlide) in the presence or absence of exogenous delta-aminolevulinic acid (ALA) was also investigated. Substituted pyrroles exhibited moderate photodynamic herbicidal effects and caused the accumulation of Pchlide only. Pyridinium analogues induced significant amounts of MPE or Pchlide accumulation and caused photodynamic injury. Dipyridyls caused greater photodynamic herbicidal injury than either pyrroles or pyridiniums, and induced the accumulation of Proto as well.

Protoporphyrinogen oxidase (Protox) is the only molecular site inhibited by the commercially available members of this herbicide class. We hypothesize that this site of action is much better for herbicidal activity than other sites of the porphyrin pathway because of the location of herbicide-susceptible Protox within the cell (the plastid envelope and the mitochondrion), the existence of a herbicide-resistant form of the enzyme in the plasma membrane (which rapidly causes accumulation of protoporphyrin IX when plastid Protox is inhibited), and two chemical features of the substrate (its relatively low lipophilicity and its non-planar macrocycle). Although enzymes of the porphyrin pathway beyond Protox can be inhibited to cause the accumulation of phytotoxic levels of porphyrins, these sites do not share the unique properties of Protox. As a result, the number of active analogues that effectively inhibit these enzymes in vivo is much smaller than for Protox, and the amount of herbicide needed for effective herbicidal action is relatively higher.

One-day-old chicks were provided 1) no CF culture and the control diet; 2) no culture and a 2% lactose diet; 3) CF culture (10(8) or 10(11) anaerobic cfu) and control diet; or 4) CF culture (108 or 10(11) anaerobic cfu) and 2 to 4% lactose diet. All groups were challenged orally with 10(4) S. typhimurium at 3 d of age. Salmonella typhimurium growth in cecal contents was significantly decreased (P < .05) at 10 d of age when 2% lactose was used in combination with CF culture containing 10(8) or 10(11) anaerobic cfu. The protection factor (log10 Salmonella control diet divided by log10 Salmonella treatment group) for these treatment groups was 2.49 and 9.26, respectively. Results indicate that birds treated with CF culture and maintained on 2% dietary lactose are protected against S. typhimurium colonization. Additionally, inoculating birds with CF culture containing a higher concentration of anaerobic colony-forming units resulted in a substantially higher protection factor.

Two experiments were conducted to determine whether heat-acclimated broilers conserve body water by reducing urine and solute (Na) excretion. In the first experiment, renal function studies were conducted at an ambient temperature (T(a)) of approximately 21 C using anesthetized 7-wk-old male broilers. Control birds reared at a constant T(a) of 24 C (Group N: noncycled T(a)) were compared with birds that had been heat-acclimated by exposure for 3 to 6 d to a daily sinusoidal cycle of 24 to 35 to 24 C (Group C: cycled T(a)). In the second experiment, renal function studies were conducted on anesthetized 5-wk-old control and heat-acclimated male broilers while they were exposed to a T(a) of 21 C (Ambient T(a): Groups NA, CA), or to a T(a) of 32 C (High T(a): Groups NH, CH). When high intravenous infusion rates (.37 mL/kg body mass per min) were used to simulate the volume expansion caused by thermogenic polydipsia, urine flow rates were significantly lower in Groups C and CA than in Groups N and NA, osmolal clearances were lower in Groups CA and CH than in Groups NA and NH, and all heat-acclimated groups in both experiments (Groups C, CA, CH) had significantly lower glomerular filtration rates (GFR), filtered loads of Na, and tubular Na reabsorption rates than the respective control groups (Groups N, NA, NH). These changes in kidney function potentially would minimize urinary fluid and solute loss when heat-acclimated broilers consume large quantities of water to support evaporative cooling. Reductions in GFR, filtered loads of Na, and tubular Na reabsorption rates also may help heat-acclimated broilers reduce the metabolic heat load associated with active (energy requiring) recovery of solute (Na) from the glomerular ultrafiltrate.

Day-old broiler chicks were provided a standard corn-soybean diet with: 1) no culture, no lactose (control); 2) dietary lactose; 3) broth culture by crop gavage; 4) culture in lyophilized powder; or 5) culture encapsulated and lyophilized in alginate beads. Two percent lactose (wt/wt) was included in the diet of chicks in Groups 2 to 5. The lyophilized powder was provided by mixing with the feed. Alginate beads were force-fed or top-dressed on the feed. All groups were challenged on Day 3 with 10(4) cfu of S. typhimurium per chick. Culture by gavage and culture in alginate beads and dietary lactose significantly (P <.05) reduced mean Salmonella colony-forming units in cecal contents by 3.4 to 5.3 log10 units at 10 d of age. Likewise, the number of cecal-culture-positive chicks in the groups provided culture by gavage or in beads was significantly less than controls. Eighty to 90% of the beads provided were consumed by the chicks within 2 h. The results indicated that cultures of cecal bacteria encapsulated and lyophilized in alginate beads were as effective as culture by crop gavage for the reduction of Salmonella colonization in broiler chicks and provide an effective and practical method of delivery.

Total parasitism was 19.5% and 22.8% for two cohorts of gypsy moth and over 70% of the parasitized larvae were also infected with virus. Compsilura concinnata (Meigen) was the most common of three tachinid species recovered. The tachinid parasitoids appear to be at least tolerant of virus infection in the host; however, their development may be influenced by a stressed host.

Females oviposit into host capitula, and lignified, unilocular galls are formed around the developing larvae in the receptacle. In laboratory studies, U. sirunaseva oviposited preferentially in closed, immature capitula with vertically oriented involucral spines. The fly posited an average of 136 eggs per female. The results of laboratory, no-choice, host-specificity tests of flies from northern Greece indicate a high degree of host specificity to yellow starthistle: U. sirunaseva reproduced on yellow starthistle, but not on closely related, North American native or commercially important species.

Until recently, the brown citrus aphid (BrCA), Toxoptera citricida (Kirkaldy), was not known to occur in the citrus-growing areas of Central and North America. However, in 1991, one alate BrCA was collected in a trap in melon fields in Costa Rica. In 1992, several colonies of BrCA were collected in Costa Rica, Dominican Republic, Haiti, Nicaragua, and Puerto Rico. In 1993, BrCA was collected in Cuba and Jamaica. This aphid is still not known to occur in the continental United States. The citrus industry could suffer severely with the introduction into the United States of BrCA. As the principal vector of citrus tristeza virus (CTV), BrCA is a threat to uninfested Citrus-growing areas of the United States. The pictorial and dichotomous keys and information on taxonomic characters, hosts, and distribution included in this manuscript will be invaluable tools to those surveying for BrCA in as yet uninfested areas.

It was easily maintained in inexpensive, portable adobe blocks. It is gentle, forages during inclement weather, also from before dawn until after dusk in fine weather. It is polylectic, does not steal nectar, flies rapidly, forages to 500 m, visits numerous flowers including blueberry and apple, and sonicates. Its active period coincides well with spring fruit blossom in the temperate zone. Females may make several nests, learning new nest locations. Dormant nests in adobe blocks were kept outdoors through five years in Maryland with minimal insulation, and the population approximately tripled each year. Details are provided regarding its behavior in Japan and Maryland, including phenology in relation to crops, wild plants and other bees, hosts, foraging behavior, effects of weather, management, substrate and nesting behavior, territorial behavior of males and mating.

Information about livestock producers' perceptions towards coyotes and about economic and actual damage caused by coyotes in the Southeast was needed. We mailed questionnaires to 825 members of the Alabama Cattleman's Association (ACA) and to 189 members of the Alabama Lamb, Wool, and Mohair Association (LWMA) to evaluate knowledge and attitudes of Alabama cattle, sheep, and goat producers towards coyotes; and determine rear or perceived economic losses caused by coyotes. Of the 1,014 livestock producers surveyed, 52 were unaccounted for, 5 respondents returned nonusable questionnaires, and 129 of the remaining 181 LWMA. producers and 544 of the remaining 776 ACA producers surveyed returned useable questionnaires. Ten percent (n = 28) of the nonrespondents were contacted and no nonresponse bias was found. Average attitudinal scores were 3.87 (ACA) and 3.86 (LWMA) and were higher (i.e., favored coyote control) for respondents with coyote damage than for those without coyote damage. Agricultural producers in Alabama lacked basic knowledge about coyotes, with mean knowledge scores of 0.37 for ACA respondents and 0.36 for LWMA respondents on a scale where 1 was a perfect score. There were several items which producers believed had been damaged by coyotes in Alabama: calves, sheep, watermelon, cows, goats, horses, domestic fowl, corn, and dogs. This diversity may be attributed to the diverse number of agricultural products generated within the state and the opportunistic feeding style of the coyote. Although relatively few respondents reported coyote damage (N 192) and average economic losses were not high (max. (x) over bar $994, min. (x) over bar = $100, total $141,340), there appeared to be an intolerance to any losses associated with coyote depredation.

In 76,103 trapnights, we collected 1,456 specimens representing 15 species. Survey efforts resulted in establishing the southernmost North American collection localities for Sorer cinereus, S. fumeus, S. hoyi, Clethrionomys gapperi, and Peromyscus maniculatus. Sorer cinereus and C. gapperi are restricted to high elevation, mesic forest communities in the Blue Ridge, while S. longirostris, Cryptotis parva, Reithrodontomys humulis, and Peromyscus leucopus are restricted to the Upper Piedmont and lower elevations in the Blue Ridge. We report the first record of Cryptotis parva and new records of S. longirostris from the Blue Ridge. Sorex fumeus and Blarina brevicauda are widespread and abundant throughout the Blue Ridge and the Upper Piedmont. Sorer hoyi, never abundant, is widely distributed in the Blue Ridge. Basic information concerning distributions and relative abundance of these small mammals should be valuable data to land managers in the Southern Appalachians and Upper Piedmont of Georgia and surrounding states.

Natchez (Alloperla natchez) and/or Chukcho (Naploperla chukcho) stoneflies, federal candidates for listing as threatened or endangered species, were found in 19 streams of the Homochitto River system, 3 streams of the Bayou Pierre system, and 1 stream of the Amite River system. Neither species was collected from tributaries of the Buffalo River. Occurrence of both species appears to be associated with stream order and canopy cover.

It implements landscape-scale management by identifying 26 habitat management areas (HMAs) totaling nearly 810,000 hectares. Within these designated HMAs, longer timber harvesting rotations will be established. Management intensity levels (MILs) will be established based on red-cockaded woodpecker (RCW) population size. The smallest populations will receive the most intensive direct RCW management while being most restrictive regarding forest management. The combination of identifying HMAs and implementing longer timber harvesting rotations and appropriate MILs should overcome the effects of past fragmentation and demographic isolation. Prescribed burning regimes will mimic historical fire regimes of southern pine ecosystems. RP Krusac, DL (reprint author), US FOREST SERV,USDA,1720 PEACHTREE RD NW,SUITE 816 N,ATLANTA,GA 30367, USA.

Several significant elements of damage were observed in desiccated material associated with development of desiccation intolerance: increased lipid peroxidation, phospholipid de-esterification, build-up of a stable free radical, supression or repression of respiratory enzymes from complex I, II and IV, An EPR (electron paramagnetic resonance) response was also detected in isolated mitochondria following in vitro desiccation. The loss of desiccation tolerance appeared to be dependent on oxygen concentration. Two highly significant correlations were independently found between respiration rates and production of a stable free radical detected by EPR. These data suggest that respiration is an important factor in the loss of desiccation tolerance. We present a model suggesting that activated oxygen formation during desiccation originates in the disruption of the mitochondrial electron transport chain with increasing leakage to oxygen so generating irreversible and lethal peroxidative damage, leading to the development of desiccation intolerance.

Oat seedlings, treated with a range of concentrations of nine different ''mitotic disrupter herbicides'', were examined by immunofluorescence microscopy of tubulin in methacrylate sections. All herbicides caused the same kinds of microtubule disruption, although the concentrations required to cause the effects differed markedly between the herbicides. Effects on spindle and phragmoplasts mitotic microtubule arrays were seen at the lowest concentrations and manifested as multipolar spindles and bifurcated phragmoplasts (which subsequently resulted in abnormal cell plate formation). At increasing concentrations, effects on mitotic microtubule arrays manifested as microtubule tufts at kinetochores and reduction of cortical microtubules resulting in arrested prometaphase figures and isodiametric cells. These data indicate that all mitotic disrupter herbicides have a common primary mechanism of action, inhibition of microtubule polymerization, and that marginal effects observed in the past were the result of incomplete inhibition and/or differential sensitivity of the microtubule arrays.

The blepharoplast, a spherical body that occurs during the last two spermatogenous divisions, organizes two microtubule (MT) arrays, one associated with a nuclear indentation and the other that organizes the spindle apparatus for the final divisions. After the last spermatogenous division, the blepharoplast reorganizes to produce two new putative MTOCs: the lamellar strip (LS) of the multilayered structure (MLS), which apparently organizes the spline microtubule array, and an amorphous zone (AM), that connects the basal bodies. Thin and semi-thin sections of this tissue were probed with antisera which recognize MTOCs in lower eukaryotes and animals to determine if any of these structures contain MTOC-associated proteins or epitopes recognized by monoclonal antisera. Gamma tubulin antibodies, which recognize only the minus ends of MTs in mammalian cells, label along the MT in all arrays found in the pteridophyte sper spermatogenous cells. Kinetochore MTs are unlabelled near the kinetochore, however. The monoclonal antibodies MPM-2 and C-9, that recognize centrosomal and nuclear epitopes in mammalian cells, label the interphase nucleus, the cytoplasm of mitotic cells, and the blepharoplast during both nuclear indentation and spindle formation. Double labelling of the blepharoplast-containing cells with anti-tubulin and either MPM-2 or C-9 reveals that the blepharoprast-associated fluorescence is the focus of the tubulin arrays. Centrin labels the reorganizing blepharoplast, the MLS, the AM, and a stellate pattern in the transition region of the flagella. These data indicate the usefulness of the structurally well-recognized MTOCs in pteridophyte spermatogenous cells in investigation of land plant MTOCs.

As has been described for dry seeds, the cells of these dehydrated leaves were shrunken, with highly convoluted walls and membranes. The membranes of all samples had a lipid bilayer organization with dispersed intramembranous particles (IMPs). Lipid droplets were very closely associated with the plasmamembrane. Chloroplasts were surrounded by a double membrane envelope and contained well-organized grana. Mitochondria were irregular in outline, and endoplasmic reticulum and cytoplasmic vesicles were present.

The isolated walls from cortical cells were less dense than the walls isolated from stelar cells. The cell walls from each tissue were centrifuged on a step gradient composed of 50 and 60% sucrose for 5 min at 900 g. After the short centrifugation time, the cortical cell walls banded at the 50/60% interface while the vascular tissue walls pelleted through 60% sucrose. An aliquot of vascular cell walls was then marked with cytochrome c. The marked cell walls were mixed with cortical cell walls and centrifuged on a 50/60% sucrose gradient and after 5 min, the vascular tissue walls were cleanly separated from the cortical cell walls. The experiment was repeated without prior separation of tissue types with another corn variety, carrot roots grown in culture, and pea roots. A clean separation of cell wall types was achieved after homogenization of intact roots in liquid nitrogen, extrusion from a nitrogen bomb, and centrifugation in sucrose gradients.

These changes reduce cell wall strength and lead to cell separation and the formation of intercellular spaces. Calcium, a constituent of the cell wall, plays an important role in interacting with pectic acid polymers to form cross-bridges that influence cell wall strength. In the present study, cationic colloidal gold was used for light and electron microscopic examinations to determine whether the frequency and distribution of anionic binding sites in the walls of parenchyma cells in the apple were influenced by calcium, which was pressure infiltrated into mature fruits. Controls were designed to determine the specificity of this method for in mure labelling of the anionic sites on the pectin polymers. The results indicate that two areas of the cell wall were transformed by the calcium treatment: the primary cell walls on either side of the middle lamella and the middle lamella intersects that delineate the intercellular spaces. The data suggest that calcium ions reduce fruit softening by strengthening the cell walls, thereby preventing cell separation that results in formation of intercellular spaces.

Reflectance is a passive sensing technique that can capture differences in the concentration of the primary plant pigments. Fluorescence and reflectance were compared for their ability to measure levels of plant stress that are of agronomic importance in corn (Zea mays L.) crops. Laboratory LIF and reflectance spectra were made on excised leaves from field grown corn. Changes in the visible region of the spectrum were compared between groups of plants fertilized with seven different levels of nitrogen (N) fertilization. A pulsed nitrogen laser emitting photons at a wavelength of 337 nm was used as a fluorescence excitation source. Differences in maximum intensity of fluorescence occurred at 440 nm, 525 nm, 685 nm, and 740 nm. Significant separations were found between levels of N fertilization at several LIF wavelength ratios. Several reflectance algorithms also produced significant separations between certain levels of N fertilization. C1 UNIV MARYLAND,DEPT GEOG,COLL PK,MD 20742.

DLE has a much longer time response than true chlorophyll fluorescence and is detectable for times ranging from milliseconds to many minutes. DLE is induced by back reactions of the photosynthetic pathway and therefore requires functional chloroplasts. It is detectable only in the dark following light excitation, yields very low energy, and decays very rapidly. DLE repetitively excited over time, which we term refreshed DLE (RDLE), shows a shoulder and broad peak in our measurements, indicating participation of at least two energy pools. DLE is altered by physiological stresses that affect chloroplasts or photosynthesis, and as illustration, plant species known to be very susceptible or very tolerant to chilling were exposed to chilling temperatures for varying times. RDLE at 0.3 s (the initial shoulder on our curves) rose in response to chilling damage in the susceptible species. The major RDLE peak was greatly inhibited in the susceptible species and showed only small changes in the tolerant species. Fluorescence measurements made on the chilling-tolerant species indicated similar responses and similar coefficients of determination were derived. These results indicate that measurement of precisely timed delayed light emission or of refreshed delayed light emission at a less precisely controlled time can be used to detect chilling stress.

The duodenum intraepithelial T lymphocytes (IEL) expressing the CD8 antigen (cytotoxic/suppressor T cells) increased in the SC and TK chickens following primary infection. However, a significant increase in the duodenum CD8(+) IEL occurred in the SC chickens which manifested as a lower level of oocyst production compared to the TK chickens following primary and challenge infections. The CD4(+) (T helper) cells increased seven days after primary infection in sc and TK chickens, and in TK chickens seven days after challenge infection. Two colour immunofluorescence analysis of duodenum IEL at 10 days after challenge infection revealed that the majority of CD8(+) IEL expressed the TCR2 antigen. Furthermore, the SC chickens showed increased TCR2(+)CD8(+) cells shortly following challenge with E acervulina. These results suggest that variations in T cell subpopulations may reflect eimerian infection-related changes in the gut-associated lymphoid tissues and that a significant increase in CD8(+) IEL in sc chickens may reflect enhanced acquired immune status in sc chickens compared to TK chickens.

All the feline isolates produced a unique AluI pattern distinct from the other C psittaci strains and were characterised by a typical fragment doublet of 185/180 base pairs. Such a homogeneity argues for their genetic relatedness and suggests their clonal origin. These data demonstrate the usefulness of MOMP-gene restriction mapping in C psittaci typing.

The shoot length is composed of two growth components: number of stem units (NSU) and mean stem unit length (MSUL). Under suboptimal conditions (Ra = 1% and 2%) most variation in shoot length (LEN) was due to variation in MSUL, and the correlation between the two components was negative. Under optimal conditions (Ra = 3% and 4%), NSU and MSUL contributed equally to the total length variation and the correlation between them was positive. Under supraoptimal conditions (Ra = 5% and 6%), the number of stem units had the greatest effect on shoot length variation and the correlation between growth components was negative. A simple allocation model was used to help interpret the changes in sign of correlation coefficient along the nutrient gradient. The model correctly predicted the sign of the correlation but not its magnitude. C1 INRA,GENET & AMELIORAT ARBRES FORESTIERS LAB,F-33611 GAZINET,FRANCE.

Most POS were found on the third antennal segment (Johnston's organ). These POS included a lanceolate peg, a bulbous peg, and two types of pit sensilla. Female flies could be distinguished from males by the predominance of the lanceolate peg on the female Johnston's organ. One type of pit sensillum with a single exterior opening was located below the cuticular surface and housed several pegs. The other type of pit sensillum was domed with a single exterior opening, housed a single peg, and the lower half of this sensillum was embedded into the wall of the Johnston's organ. This type of pit sensillum was also found on the sixth antennal segment of both sexes. A bulbous peg was found on the palps of both sexes. No POS were found on the mouth parts sheath. Specimens were prepared in the traditional manner for scanning electron microscopy examination. Also specimens were embedded in Paraplast and sections of the Johnston's organ clarified the internal structure and distribution of the pit sensilla on this organ.

PEG reduces the water potential of osmotic solutions but may limit oxygen availability to germinating seeds. The purpose of this study was to determine whether seed immersion in PEG solution had a detrimental effect on total germination percentage and germination rate of six grass species. Bouteloua curtipendula, Cenchrus ciliaris, Panicum coloratum, Eragrostis lehmanniana, Pseudoroegneria spicata and Leymus cinereus seeds were germinated over the water potential range of 0 to -1.5 MPa at PEG solution depths of 0, 1, 3, or 5 mm. Total germination percentage and germination rate were generally greatest at 1 mm depth even in the pure water treatments. Reduced germinability at 0 mm depth may have been caused by the lower hydraulic conductivity of the medium. Reduced germinability at 3 and 5 mm depth may have been caused by decreased oxygen availability to the seeds. A reduction in germination was also apparent at 3 and 5 mm depth in pure water treatments, indicating that oxygen diffusion between the seeds and the air/solution interface was more important to oxygen availability than was the presence or absence of PEG per se.

We investigated the utility of sulphuric acid and chloroethanol treatments to improve germination of the cultivar 'Alamo'. Freshly-harvested seeds were placed in petri dishes in a germinator (35 degrees C, 25 degrees C), and germination counts were made for 32 days. A 10 minute sulphuric acid treatment was the most effective treatment in increasing total germination. Regression analysis indicated that a 17 minute acid treatment time maximized rate of germination. With chloroethanol, a 15 minute treatment time was optimum. Because chloroethanol treatment was no more effective than acid in improving either total germination or speed of germination (coefficient of velocity), and the compound is highly toxic, chloroethanol is not recommended as a treatment to break dormancy in switchgrass. Acid treatment also improved germination of freshly harvested seed of the cultivars 'Caddo' and 'Kanlow'. Acid treated and control seeds of the three cultivars were planted in potting mix, to determine if effects observed in petri dishes occurred in other media. Acid treatment had little effect on Alamo and Caddo, but improved vigour of Kanlow seedlings while reducing emergence. A 10 minute acid treatment allows rapid generation of appreciable numbers of seedlings and eliminates the need for lengthy storage or stratification treatments. This technique should be useful in switchgrass breeding programs. RP TISCHLER, CR (reprint author), USDA ARS,GRASSLAND SOIL & WATER RES LAB,808 E BLACKLAND RD,TEMPLE,TX 76502, USA.

Germination data over time were transformed to probit values, and viability equations were calculated for each species by multiple regression analyses. After 10 years, the two angiosperms (L. styraciflua and P. occidentalis) have exhibited typical behaviour for orthodox seeds, while the gymnosperms P. taeda and P. elliottii have not. The atypical behaviour of the pines is a positive relationship between germination and seed moisture content after several years of storage at 10-degrees-C. This response became evident in p. taeda after 4 years and in P. elliottii after 7, and may possibly be the result of cellular repair processes, although there is no direct evidence for it. Viability equations for the two angiosperms calculated with 5 years of data appear adequate, but results with the pines suggest that as may as 8 or 10 years may be required to accurately model their responses. Regression coefficients for the temperature parameters were similar to published values for other tree species, but the moisture coefficients were not.

We subjected two separate populations of kleingrass to three cycles of recurrent selection in a growth chamber for increased shoot mass at 14 days post emergence. These populations were the cultivar 'Selection 75' and the population 'DT' (selected for drought tolerance and having a broad germplasm base). The cycle 3 Selection 75 and DT populations were evaluated for seed mass, seed starch content, shoot mass, and seedling root characteristics. Seed mass and seed starch content were significantly higher in cycle 3 Selection 75 seed compared with the base population. The same trends were noted in the DT populations, but the differences were not significant. Seedling vigour of base and cycle 3 populations were compared in two separate experiments. In Experiment 1, seedlings were grown in a glasshouse with seedling harvests being performed at 7, 14, 21, and 28 days after emergence. In Experiment 2, seedlings were grown in a glasshouse with solar radiation supplemented with 16 hours of illumination by overhead lights. In both experiments, the cycle 3 populations performed better than the corresponding parental populations, with cycle 3 populations being much more vigorous than cycle 1 populations in Experiment 2. In Experiment 1, the cycle 3 Selection 75 seedlings were most vigorous, while in Experiment 2 (under a long duration of high light intensity), seedlings in the cycle; DT population had almost twice the mass of the corresponding cycle 3 Selection 75 seedlings. Results indicate that selection was successful, and may have operated on different pools of genetic variation between the two populations. C1 USDA ARS,GRASSLAND SOIL & WATER RES LAB,TEMPLE,TX 76502.

In region 2, stands were classified by whether they were part of the main distribution, part of the forest-high desert ecotone, or disjunct populations. Estimated selfing was also related to filled seed percent in a sample of trees from regions 2 and 3 and to seed survival after several months of storage at room temperature in trees from region 1. Effects of crown position were examined in 6 trees. Mean S was 0.091 and 0.076 if trees were excluded that were in disjunct stands and in stands with ponderosa pine as a minor component. Median S was 0.056. Difference among regions was not significant; difference among stand types was. Heterogeneity among trees-in-regions was large and significant in all regions. S was significantly, but weakly and inversely, correlated with filled seed percent and with seed storability. Seeds from upper crown had lower estimates of selfing than seeds from mid and lower crown, but the difference was not significant.

Both methods produce similar estimates of lethal equivalents. However, the 2 methods differ in 2 respects: (1) COMB makes inferences to particular individual(s) in the population, while MCM makes inferences to the entire population; and (2) COMB estimates the number of lethal loci which is translated into lethal equivalents, while MCM directly estimates lethal equivalents. In a previous paper KANG et al. (1992) failed to recognize the second difference between COMB and MCM, and overestimated lethal equivalents in Salix viminalis. The revised estimate of lethal equivalents using COMB is 1.8, which is similar to that (1.69) estimated by MCM previously. C1 UNIV WISCONSIN,DEPT FORESTRY,MADISON,WI 53706.

After 22 years, height, d.b.h., and survival measurements revealed that local trees (from within 100 miles north and south of the plantation) had the greatest survival at all locations, and those from areas 200 miles south of the planting site grew significantly taller than trees from more southerly locations. Survival in the Minnesota and Iowa plantations was highly correlated with latitude and longitude of seed source; northern and western seed sources had higher survival. Height and d.b.h. correlations were highly significant in all plantations. High heritabilities implied that much of the geographic variation in height and d.b.h. is under genetic control and that seed source selection should be included in black walnut improvement programs.

Mating parameters from seed orchard populations were not significantly different from those of the natural population. The mean fixation index was less than 0.1 in all three populations suggesting very low rates of inbreeding in this species in seed orchards as well as in a natural setting.

The stands were found to be substructured into mosaics of putative clones and trees of seedling origin. The level of genetic diversity was high: observed per locus heterozygosities averaged 0.382; number of alleles per locus averaged 2.9. Significant deviations from Hardy-Weinberg equilibrium were detected for up to five of the nine loci studied. Deviations resulted from an excess of heterozygotes at the 6PG-2, MDH-1, and CTO-1 (MA only) loci, and a deficiency of Heterozygotes at the CTO-2 and PER-8 loci. Overall, positive mean F-IS values indicated slight deficits (2.3%) of heterozygotes within populations. Positive assortative mating, as a result of crossing within clonal and/or family patches in stands, may be responsible. A mean F-ST value of 0.064 provided evidence for moderate differentiation between the two populations. Clonal structure had a small effect on the computation of population genetic statistics for these two stands. C1 OHIO STATE UNIV,WOOSTER,OH 44691. US FOREST SERV,NE FOREST EXPT STN,HAMDEN,CT 06514.

Cone and seed traits other than fertility, but including germination, were almost exclusively under maternal influence. The relations between 3 measures of fertility and inbreeding coefficient (F) were linear or predominantly linear. Our results were very similar to those previously reported by WOODS and HEAMAN (1989), and combining their results with ours gave 40.2, 30.9, 23.2, and 1.15 filled seeds per cone after cross, half-sib, full-sib, and self pollination, respectively. Selfing appeared to reduce seed set more in the orchards than in natural stands. Assuming linear relations between F and fertility and between F and vigor, it was shown that partial selfing between zero and 50% has a greater impact than partial sibbing on seed set; but that partial sibbing, particularly full-sibbing, has the greater impact on population vigor and wood production.

Only 5% of survey respondents felt that coyotes should be eliminated, but when asked if coyotes should be completely protected, 39% agreed, 40% disagreed, and 23% were willing to pay an average of $5.05 per year for coyote protection, while a similar number (19%) were willing to pay an average of $4.20 per year to control coyotes. These contingent valuation results also indicate that coyotes have existence value. Only about 20% of respondents had even seen a coyote, and younger, urban residents in southern New England who do not hunt were most likely to be willing to pay to protect coyotes.

Night temperatures as high as 18-degrees-C have been associated with decreased biomass accumulation. The objective of this study was to observe directly the leaf CO2 assimilation rates of peanut leaflets (cv. 'Early Bunch') on days following exposure to various night temperature treatments. Measurements were made both after a single night of exposure and after multiple nights of exposure. A linear decrease in CO2 assimilation rate with night temperature was found between 18 and 4-degrees-C. Below 16-degrees-C, a single, cool night treatment resulted in decreased CO2 assimilation rates compared to plants maintained at ambient night temperatures (>20-degrees-C). Repeated exposure to nights at 16-degrees-C were found to result in leaflet CO2 assimilation rates which were approximately 90% of the control. Repeated exposure at 13-degrees-C resulted in stabilized CO2 assimilation rates over several days at 80 to 85% of control rates. These results indicate a loss in the ability of peanut to accumulate biomass whenever night temperatures are consistently at or below 16-degrees-C.

All biocides significantly reduced the populations of target organisms, except dimethoate-carbofuran, which failed to reduce the number of microarthropods. All biocides also affected populations of non-target organisms. Oxytetracycline-penicillin reduced lengths of active hyphae. Captan reduced nematode and bacterial numbers.

Rates of percolation and recharge are of major interest to those concerned with the quantity and quality of water in our aquifers. Evaporative loss, precipitation, and water accumulation were measured on 0.9-m-long columns containing soil topped by sand and gravel mulches in the field for 388 d. Results show evaporation reductions due to gravel and sand mulches of differing thickness, color, and particle size on soil surfaces. These data show effects of mulch thickness, particle size, and color on the steady and transient components of evaporation and provide coefficients for equations to help predict effects of such mulches on evaporation and accumulation of water in soils and aquifers. Gravel mulches 5 cm thick resulted in accumulation of 80 to 85% of the annual precipitation. C1 USDA ARS,DURANT,OK. COLORADO STATE UNIV,FT COLLINS,CO 80523.

Because SOM is composed of a series of fractions, management practices will also influence the distribution of organic C and N among SOM pools. Our study examined SOM fractions that are occluded within the aggregate structure. Aggregates were disrupted by sonication and the disrupted soil suspensions were passed through a series of sieves to isolate size fractions. Densiometric separations were carried out on the size fractions, creating size-density fractions. Fine-silt-size particles having a density of 2.07 to 2.22 g/cm3 isolated from inside macroaggregates contained the highest percentage of total soil C and N for all cultivation treatments and, because of its properties, will be referred to as the enriched labile fraction (ELF). As cultivation intensity was reduced, the amount of N in the ELF increased from 110 mg N/kg in the bare fallow treatment to 405 mg N/kg in the no-till treatment. About 5% of the N in the ELF was mineralized during a 28-d laboratory incubation, averaged across treatments. The proportion of N mineralized from the ELF (4.7%) was significantly higher than from intact macroaggregates (2.1%), which suggests this fraction may be protected from decomposition within the aggregate structure. We postulate that the ELF is a byproduct of microbial activity and that it contributes to binding microaggregates into macroaggregates in cultivated grassland soils.

Although adequate for farm planning and agricultural production, the surveys lack information on spatial and temporal variability of soil attributes. Such information is increasingly needed for modeling of water flow and contaminant transport, in geographical information systems (GIS) applications, and for environmental impact assessment. The proposed approach combines spatially interpolated distributions of measured values with soil map unit delineations within a GIS framework. Data analysis provides insights into the potential continuity and variability of attributes within and between the map units. The result is a map that preserves the map unit boundaries but incorporates spatial variability of attribute data into map unit delineations. The approach is illustrated using bulk density and hydraulic conductivity data for surface soil horizons at a farm scale. Semivariograms based on measured values are constructed and cross-validated. Subsequently, GIS overlays of soil survey attributes and kriged overlays of measured data can be prepared. These GIS overlays can be combined pixel by pixel according to a simple rule. Results indicate that spatial distributions of bulk density and hydraulic conductivity are similar to original map unit delineations, but include aspects of the attribute continuity and variability from geostatistical analysis. Such combined representations of bulk density and hydraulic conductivity are superior, because they contain more information than either the soil survey map, or the kriged interpolation of discrete data.

Ponded infiltration rates were measured in corn (Zea mays L.) fields at four positions relative to plants and to crop rows: center of a trafficked interrow (TRK), center of an untrafficked interrow (UNT), between corn plants in a row (BPIR), and directly over the base of a plant in a row (OPIR). Measurements were taken in chisel-plow plots during 1990 and 1991, and in no-till plots during 1991. A Canisteo silty clay loam (fine-loamy, mixed [calcareous], mesic Typic Haplaquoll) was the predominant soil type in the plots. In chisel-plow plots, infiltration rates for TRK and UNT positions remained relatively constant during both years, with temporary increases after tillage or cultivation. At BPIR and OPIR positions, infiltration rates increased steadily over the growing season. Infiltration rates at the OPIR position increased from 43 to 211 mum s-1 in 1990 and from 63 to 257 mum s-1 in 1991. At the end of both growing seasons, the OPIR position had the greatest infiltration rate, and the TRK position the lowest. In no-till, infiltration rates at all positions remained relatively constant throughout the 1991 growing season. Infiltration rates at BPIR and OPIR positions were not different from each other, were greater than 200 mum s-1, and were higher than rates at TRK and UNT positions. High potential infiltration rates in the row, especially around the bases of corn plants, have implications for the management of row-banded chemicals. C1 USDA ARS,NATL SOIL TILTH LAB,AMES,IA 50011.

The variables were soil OM content of the upper 30.5 cm together with all combinations of three postplanting soil available N levels (55, 90, and 125 kg N ha-1 as NO3-N to 1.2 m) and three water levels. Water levels were uniformly maintained with a trickle system that independently metered water to each plot for each soil available N level. Pretillering spring wheat (Triticum aestivum L.) plant population decreased as soil OM content decreased in 3 of 4 yr. On an annual basis, highest total aerial dry matter and grain yields were associated with highest OM contents. The contribution of 1 Mg OM ha-1 to soil productivity, across the range of 64 to 142 Mg OM ha-1, was calculated as equivalent to 35.2 kg ha-1 for spring wheat total aerial dry matter and 15.6 kg ha-1 for grain yield. Loss of productivity associated with a depletion of soil OM in the northern Great Plains is primarily a consequence of a concomitant loss of fertility.

Changes in surface runoff and sediment production were evaluated with time following fall and spring burns at two different soil and vegetation type locations in southeastern Arizona. Rainfall simulations were conducted immediately after prescribed burns on four replicate areas and 1 yr later following a repeat burn on the same areas, and compared with paired unburned areas. The burn treatment and evaluation sequence was repeated in a second year on new areas to evaluate differences in years. After the first burn, runoff and sediment production on unburned and burned areas were similar within locations, and were greater at one location than the other. One location showed significantly more runoff and sediment production in the fall season on both unburned and burned areas after the first burn treatment. There was significantly greater runoff and sediment production from the burned areas after the second burn and the burned areas were now similar between locations. Runoff and sediment production for the fall season and for the second year on the 1-yr-old areas was higher at both locations, regardless of treatment. The increases in runoff and sediment production were greater from the burning than the season or year effects after 1 yr. The management implications for these locations and conditions are that, immediately after a rangeland burn, runoff and sediment production maybe unchanged, but within 1 yr significant increases can occur and significant seasonal and yearly differences may occur irrespective of a burn.

Engelm.] forests of central Oregon by supplementing detrital C and nutrient pools. This study was conducted to determine the decomposition rate and nutrient retention of downed lodgepole pine boles, and to characterize their effect on soil biological and chemical properties. Three sites, in stands recently damaged by insects, had an average downed wood biomass of 38.7 Mg ha-1. Bole-wood decay was rapid once in contact with the soil surface. The decomposition rate constant based on the single-exponential decay model was 0.027 yr-1 and the turnover time of C was 37 yr. Nitrogen content per unit volume was 75% greater for downed boles after 38 yr of decay compared with their initial content. A net release of Ca (38%), Mg (54%), and K (42%) was found, but P content remained constant during decomposition. With the exception of Mg, however, downed boles comprised < 3% of the combined mineral soil, 0 horizons, and downed wood nutrient pool. In comparison, downed boles comprised 23.5% of the detrital C. Microbial biomass C (C(M)) and the ratio of microbial C to total organic C (C(M)/C(T)) were significantly greater in the surface 0 to 4 cm of soil beneath rapidly decaying boles than in soil without a bole-wood component. The C(M)/C(T) ratio remained elevated throughout the advanced stages of wood decomposition, indicating a long-term change in the efficiency of C utilization by soil microbial communities associated with decaying wood.

A technique incorporating use of both a video camcorder and wood blocks was developed to measure surface soil velocity. Soil velocity direction at the tool surface was measured from scratch marks on the tool. Velocity measurements were made for three sweeps with different rake angles operated at three speeds and two depths. Surface soil moved in either of two modes: V-flow (upward and laterally in the shape of one leg of the letter V) or snowplow (initially moving upward and subsequently being buried in a wave of soil). Surface soil velocities were uncorrelated with velocities on the tool surface, indicating that soil flow paths over the sweep were not parallel. The ratio of vertical to lateral soil flow at the tool surface increased with larger rake angle and was greater than the ratio at the soil surface. At the soil surface, vertical velocity was greater near the nose than near the wing tip and velocity parallel to the travel direction increased with increased speed and rake angle.

A low-cost clay and unmodified cornstarch were preblended dry, processed with water and herbicide in the extruder at 70-95 degrees C, and extruded at 65% solids using an intense mixing screw. The extrudates were dried, milled, sieved (14-20 and 20-40 mesh), and analyzed for level of entrapped herbicide. The effect of various levels of clay and other variables on encapsulation efficiency, swellability, and release rates of the products in water were determined. The study showed that clay in the preblends of up to 50% had rather small effects on encapsulation efficiency and release rates of the products in water. As little as 20% starch in the blends remarkably slowed the release rates compared to that of clay alone. Processing the clay, herbicide and water without starch in the extruder significantly slowed the release rate compared to an unprocessed mixture of clay, metolachlor, and water. In all cases metolachlor was released more quickly than atrazine from the products (10-27% active ingredient).

Unfortunately, these same analytical procedures may, in themselves, alter the composition of the food being analyzed. This paper demonstrates that the chromatographic profiles of volatiles from cooked and from cooked-stored ground beef are directly affected by and related to the temperature used to purge the volatiles from the sample, the temperature of analysis, and the end-point cooking temperature of the sample. Analytical efficacy and recovery is minimal when the samples are purged at 50 degrees C due to inefficient extraction of the flavor volatiles. Misleading chromatographic profiles occur when samples are purged at temperatures over 90 degrees C due to conversion of one volatile form to another. Optimal volatile extraction/purging and limited conversion of volatiles to other forms is observed at temperatures of 70-75 degrees C. The data suggest that a thorough examination of the effect of temperature on volatile production must be performed prior to analytical appraisal of the food's flavor-volatiles if the true flavor-profile or flavor-picture of the food is to be known.

Such interactions with inhibitors from soybeans and with lectins from lima beans facilitate heat inactivation of the potentially toxic compounds, resulting in beneficial nutritional effects. Related transformations of protease inhibitors in soy flour are also beneficial. Since thiols are potent nucleophiles, they have a strong affinity for unsaturated electrophilic centers of several dietary toxicants, including aflatoxins, sesquiterpene lactones such as elephantropin and parthenin, urethane, carbonyl compounds, quinones, and halogen compounds. Such interactions may be used in vitro to lower the toxic potential of the diet, and in vivo for prophylactic and therapeutic effects against oxidative damage. A number of examples are cited to illustrate the concepts and mechanisms of using sulfur amino acids to reduce the antinutritional and toxic manifestations of food ingredients.

The Mohinora population loosely grouped with the var. mexicana population, suggesting inclusion in that taxon; both of these populations showed close affinities with U.S. populations of P. engelmannii, supporting retention of varietal status in P. engelmannii. Picea martinezii was similar to P. chihuahuana, but all analyses showed the two taxa to be clearly distinct, justifying the retention of P. martinezii as a separate species. Interestingly, P. engelmannii var. mexicana overlapped in morphologic and phenolic variation with P. sitchensis. C1 UNIV TEXAS,DEPT BOT,AUSTIN,TX 78713. US FOREST SERV,LEAVENWORTH,WA 98826.

They have variously been synonymized, recognized as varieties of S. megistacrolobum, or recognized as distinct species. This study examines 26 morphological characters of 115 living accessions of these two species, plus six accessions of two related species in series Megistacroloba, S. boliviense and S. sogarandinum. All measurements were taken from living accessions planted in a common garden plot. Solanum megistacrolobum and S. toralapanum could be distinguished phenetically only by a combination of the 21 characters that showed statistically significant differences between the two taxa. No individual characters provided consistent discrimination, and there was frequent overlap of ''species-specific'' characters between taxa.

Petota) species, classified in series Megistacroloba, that together are distributed from southern Peru to northwestern Argentina. They have variously been synonymized, recognized as varieties of S. megistacrolobum, or recognized as distinct species. We used 22 single- to low-copy random genomic DNA probes from potato, hybridized to total DNA digested with DraI, EcoRI, EcoRV, and HindIII, to investigate their taxonomic status. We also investigated the hybrid origin of S. raphanifolium and the hybrid origin of S. acaule subsp. aemulans. Our results are concordant with a separate morphological study, showing weak differentiation between S. megistacrolobum and S. toralapanum, but possible only with multivariate methods. These combined morphological and molecular results most closely fit the contemporary treatment of S. megistacrolobum and S. toralapanum at the varietal level. We propose the new combination S. megistacrolobum subsp. toralapanum in order to bring consistency to taxa within sect. Petota, where different authors recognize identical taxa as varieties or subspecies. Our results also show possible hybridization between S. megistacrolobum and S. acaule subsp. aemulans in Argentina, discount the hybridization hypothesis of S. raphanifolium, and show that the species-specific bands of S. albicans relative to S. acaule are shared with many other species in sect.

The seedless female flowered P79-101 was hybridized with three V. rotundifolia parents and they produced 102 ovules. From these ovules, 44 embryos developed and from them 20 plants were grown. Isozyme analysis and morphological traits confirmed that 19 of the plants were hybrids. Sixteen were planted in the experimental vineyard at Fresno, Calif. One seedling, C41-5, has produced seedless fruit that appears to be stenospermocarpic based on fruit and aborted seed size. Its fruit were almost as large as Thompson Seedless (stenospermocarpic) and at least twice the size of parthenocarpic fruit of Black Corinth and C41-7, a seeded hybrid with many parthenocarpic fruit. Aborted seeds of C41-5 were larger but not significantly different from those of Thompson Seedless, while parthenocarpic fruit had aborted seeds that were smaller than C41-5. Seed of C41-7 averaged almost 10 times the weight of aborted seeds from C41-5. This is the first report of a stenospermocarpic seedless hybrid of V. Vinifera X V. rotundifolia.

Initial weight and pH measurements were taken with additional readings made after two three-week culture periods. Embryo counts were made at the conclusion of the experiment. Significant differences were observed between genotypes for the number of large embryos, but not in total number of embryos, There was a significant difference between genotypes for the percent increase in total embryo weight, During the first culture period, pH 5.5 had the greatest percent increase in total embryo weight for both genotypes. Additionally, pH had no effect on the number of embryos produced, but genotype 47-447-7 (92) had many large size embryos at the higher pH levels, The average total embryo weights for genotypes 2-17-2 (92) and 47-447-7 (92) for all buffer levels in the first three-week period increased 362-fold and 800-fold, respectively. The total number of embryos in genotype 2-17-2 (92) was influenced by buffer level treatments, Genotype 2-17-2 (92) during the first three weeks showed significant differences in the percent increase in the total embryo weight between buffer level treatments.

After a period of growth, embryos were fixed, embedded, sectioned, and examined by light microscopy. The zygotic embryos produced numerous somatic embryos. The origin of the somatic embryos was the epidermal layer of the hypocotyl or cotyledons. The first stage of somatic embryogenesis was a periclinal to transverse division of epidermal cells. Further cell divisions resulted in a globular cell mass that developed into a heart-shaped proembryo and later to a torpedo-shaped embryo. Additional evidence of epidermal origin was observed during later stages of somatic embryo development. There was a lack of continuity between the embryo and the epidermis, likewise, the continuity of the epidermal cell layer immediately under the somatic embryo indicated its epidermal origin. Verification of the epidermal origin of somatic embryos establishes the validity for the use of vectors such as Agrobacterium tumefaciens or biolistics for zygotic embryo transformation.

The effect of atypical industry practice-several months of fumigated storage-on residue levels has come into question. Thompson Seedless grapes were fumigated with 2000 ppm SO2 for 30 minutes and stored at 0 degrees C for 15 consecutive weeks. The concentrations of sulfite observed in grapes ranged from 0.7 to 3.2 mu g/g. Sulfite in grapes frozen immediately after aeration or stored at 0 degrees C, 10 degrees C, 20 degrees C, or 30 degrees C for 24 hours after fumigation did not differ significantly. These data suggest that current industry practices leave sulfite residues well below the official FDA tolerance level.

Sperm are stained with Hoechst 33342 which binds to the DNA helix in an amount proportional to the amount of DNA thus forming the basis for the method. Calves of predicted sex have been born using sorted sperm in conjunction with IVF resulting in embryos for transfer. Swine, rabbits and sheep have been produced using surgical insemination with smaller numbers of sperm than are required for artificial insemination. The inability to accrue large numbers of sperm in a short period of time precludes standard insemination techniques with sorted sperm. All offspring that have been born using this technology have been morphologically normal, and swine and rabbit offspring have shown normal reproductive function through two generations. Research to streamline hardware and improve staining technology is ongoing, while at the same time the method is being developed for the commercial embryo market.

It was recently reported (Roberts et al. (1987) J. Med. Chem. 30, 1891-1896) that this thiazolidine, D-glucose-L-cysteine (DGC), offered no significant protection against the hepatic injury caused by 5 mmol/kg of acetaminophen in mice, suggesting that the cysteine present as DGC is poorly bioavailable in vivo. In the present study, fasted male ICR mice given 1.6 or 2.6 mmol/kg of acetaminophen sustained hepatic injury, estimated by elevations in plasma alanine aminotransferase (ALT) activities. Administration of 2.5 mmol/kg of N-acetylcysteine (NAC) 1 h before acetaminophen given i.p. prevented the rise in plasma ALT activities, apparently through support of glutathione (GSH) synthesis. Administration of 2.5 mmol/kg of DGC prior to acetaminophen resulted in slightly lower mean plasma ALT activities than were observed in animals given saline before acetaminophen, but the effect was not statistically significant. When DGC was given 1 h before p.o. administration of 1.6 or 2.6 mmol/kg of acetaminophen, the protective effects of DGC were statistically significant (P < 0.01, 0.025, respectively), although NAC afforded significantly greater protection than did DGC at the higher dose of acetaminophen. Given 4 h before acetaminophen, DGC attenuated acetaminophen-induced increases in plasma ALT activities significantly, whereas NAC was without effect. These results indicate that the cysteine in DGC is at least partially bioavailable in vivo and, further, that DGC may function as a slow release formulation of cysteine.

Polymorphic loci that could be scored from fin tissue included aconitate hydratase (mAH(*)), glucose-6-phosphate isomerase (GPI-B-*), glutathione reductase (GR(*)), phosphoglucomutase (PGM(*)), and UDPglucose-hexose-1-phosphate uridylyltransferase (UGHUT-2(*)). Inheritance of observed electrophoretic variation was consistent with Mendelian segregation of codominant alleles in progeny selected randomly from the individual crosses. Although mAH(*), GPI-B-*, PGM(*), and UGHUT-2(*) appeared to assort independently within the limits of the data, strong evidence for linkage of GR(*) and PGM(*) was obtained (19.7% recombination, P less than or equal to 0.001 for data combined from two informative pedigrees); this linkage was designated Ictalurus punctatus linkage group I. This study represented a first step in assembly of a catfish gene map large enough to provide genetic markers for each catfish chromosome to enable detection of specific loci associated with traits of economic importance by genetic linkage analyses. For the polymorphic loci studied here, no consistent association of genotype with average body weight was observed. C1 GENET ANAL INC,SMITHVILLE,TX 78957.

Cutthroat trout spawned in June as flows subsided after peak stream discharge. During spawning, minimum and maximum water temperatures ranged 4-9 degrees C and 16-20 degrees C, respectively. Trout spawned where water depths averaged 20 cm beside redds and 22 cm upstream of redds. Water velocities averaged 42 cm/s beside redds and 46 cm/s upstream of redds. More than 80% of the redds were constructed in water 10-30 cm deep with velocities of 25-60 cm/s. Trout spawned in gravel with particles up to 100 mm in diameter. Most of the substrate was smaller than 32 mm; an average of 20% was less than 6.35 mm and 5% was less than 0.85 mm. The geometric mean particle size of the spawning gravel averaged 16.6 mm and the fredle index averaged 8. Microhabitat conditions differed within completed redds. Water depth decreased and velocity increased from the redd pit downstream to the leading edge of the tailspill and to the tailspill crest. The redd shape may facilitate movement of water through the egg pocket. Redds averaged 1.58 m long by 0.60 m wide, and the pit covered an average of 46% of the redd area. Water depths and velocities in redds were correlated with water depths and velocities adjacent to redds. Redd dimensions were typically not correlated with water depths, velocities, or particle size distributions, suggesting that other factors such as the size of spawning fish may influence redd dimensions.

Under certain conditions, both heating and oversprays enabled small lots of sticky cotton to be roller ginned at normal throughput rules. However, the heating and overspray treatments did not improve textile processing. None of the treatments could be carded at the target rate of 27.2 kg/h (60 lb/h) even after blending 50/50 with nonsticky cotton or increasing the amount of overspray on the fiber. Further research is yet needed in this area. C1 USDA ARS,SAA,COTTON QUAL RES STN,CLEMSON,SC. COTTON INC,AGR RES,RALEIGH,NC.

Surfactants are usually added to formulations to help overcome these problems, but are sometimes ineffective. Some workers have found dynamic surface tension (DST) to be more reliable than equilibrium surface tension (EST) as a measure of surfactant effectiveness. Diffusion-controlled surfactant adsorption generally produces the quickest surface tension reductions as newly generated interfaces age. A diffusion model was developed for DST of three surfactants representing those commonly used in agrochemical formulations: Tween 20, Triton X-100, and Triton X-405. A bulk-solution diffusion model was developed which, together with the DST model indicated apparent diffusive surface-layer thicknesses of a few micrometers. Apparent diffusion coefficients were determined from DST data obtained by oscillating-jet and maximum bubble pressure methods for aqueous solutions. Good agreement of the models with DST data indicated that adsorption processes for the surfactants were diffusion-controlled. Surface ages required to achieve EST for the surfactants were greater than time intervals observed for droplet deformation and recovery in impaction.

This study was conducted to determined the size and horizontal placement of riprap to stabilize the downstream channel geometry below pipe spillways with submerged flow conditions. Dimensionless relationships were developed to estimate the riprap size and its design size variation with distance from the outlet in the downstream channel using a laboratory scaled physical model with the following test conditions: pipe diameter (D(o); 0.0628 and 0.0884 m); three submergence levels (TW/D(o); 0.7, 1.0, 2.0, and 3.0); five plunge depths (Z/D(o); -2.5, -1.75, -1.0, -0.5, and 0.0); and flows varying from 0 to 7.2 Q2/gD(o)5. The resulting equations were tested and validated with additional laboratory studies with the following conditions: D(o) of 0.0884 and 0.0628 m; W/D(o) of 4.0, 8.0, and 11.3; Q2/gD(o)5 of 1.04, 1.13, 1.64, 1.99 2.21, 5.37, and 3.18; TW/D(o) of 0.8, 1.0, 1.5, and 2.0; and Z/D(o) of -2.5, -1.75, -1.0, -0.5, and 0.0 for selected cases These validation tests resulted in minor changes in the design equations over the range of the variables. An example design problem is presented to illustrate the use of the recommended design method. The design equations and method will result in stable riprap without scour for submerged pipe outlet flow conditions over a wide range of flow conditions.

This article presents comparisons of using measured versus estimated theta(h) and K(h) data to simulate evapotranspiration, infiltration, runoff, and drainage with the PREFLO and DRAINMOD water management models. Both models reacted similarly to the estimated data by altering the simulated volumes of ET and drainage. The models were most sensitive to differences in the K(h) data at tensions between 0 and 1.5 m. PREFLO was more sensitive than DRAINMOD to the saturated water content estimated from soil texture. The ability to simulate soil-water storage and movement with PREFLO or DRAINMOD was more a function of input data accuracy than the model.

Existing empirical relationships generally underpredicted observed hydrograph time parameters on nine Coastal Plain and Flatwoods watersheds, with the standard error of estimate ranging from 63 to 132 % of observed means. Hydrograph time parameters from flatland study areas were related to watershed physical characteristic and geomorphic data. The simple parameter, length of main channel, proved superior to all other simple or complex watershed characteristics for explaining observed variations in watershed time-of-concentration and hydrograph time-to-peak.

This study was conducted to determine the horizontal and vertical distribution of an insecticide applied with a center pivot irrigation system to a corn crop. The experiment was conducted at Tifton, Georgia, using a 140 m long, three-span center pivot system equipped with conventional impact sprinklers operating at 487-kPa pressure. An insecticide formulated with peanut oil was injected at a rate of 0.56 kg/ha with a calibrated metering pump into the irrigation mainline of the center pivot system with a gross irrigation application of 2.54 mm. Irrigation and chemical application uniformity were measured with glass collectors spaced 6.1 m apart along the lateral on bare soil. At three sites along the lateral at the midpoint of each span, the vertical chemical concentration was measured from above the canopy, at the third, sixth, and ninth leaf below the top of the corn plants. The mean irrigation application depth was 3.00 mm with a distribution uniformity of 93.5%. The mean chemical application amount was 0.79 kg/ha with a distribution uniformity of 83.9%. Chemical concentrations in relation to that in the water above the canopy declined 59, 49, and 39% at the third, sixth, and ninth leaf from the top of the plant with approximately 50% of the applied chemical retained on the corn foliage. The chemical distribution was less uniform than the water distribution and indicates the necessity of uniform irrigation applications to achieve high-chemical application uniformity.

Contour factors (P) that represent the conservation benefit of supporting practices were computed as ratios of soil loss rates from these field plots.

The P values computed from annual totals ranged from 0.58 for low rainfall erosivity to 0.22 for the highest erosivity. These values add to the database of soil loss throughout the year that demonstrates the value of contour farming. They are also useful for validation of the P values computed by RUSLE (revised USLE) that considers slope, ridge height, storm severity, and off-grade contouring.

CHANNEL PROCESSES SO TRANSACTIONS OF THE ASAE LA English DT Article DE SOILS EROSION; MODELING; SENSITIVITY ANALYSIS; MONTE-CARLO; WATERSHED AB This is the second part of a two-part article describing the results of a sensitivity analysis of the Water Erosion Prediction Project (WEPP) watershed model for rangeland applications. The first article presented the sensitivity of the hillslope component due to variations in hillslope input parameters as well as the implications of applying Monte Carlo simulation and regression analysis to estimate the sensitivity of a complex, non-linear model. This second article presents the sensitivity of the WEPP channel component in predicting hydrologic and erosion watershed responses due to variations in estimating channel parameters. Both model sensitivity studies were conducted using information from a representative semiarid rangeland watershed in the southwestern USA. Three major sources of errors were identified in predicting the stream flow discharge at the watershed outlet: 1) errors in rainfall characteristics; 2) errors in estimating the hydraulic conductivities of both hillslope and channel; and 3) errors in representing the antecedent watershed soil moisture condition. Model sensitivity to channel hydraulic conductivity confirmed the importance of channel transmission losses in predicting the flow in ephemeral channels. Estimates of sediment detachment occurring in the channel bed and total sediment yield at the watershed outlet were highly sensitive to total Manning's n, but only slightly sensitive to erodibility and critical shear stress channel parameters.

Moisture contents of the soybeans ranged from 7 to 20%, wet basis. A commercial instrument that measured the dc conductance of the soybeans as they passed between crushing-roller electrodes gave moisture contents with a standard error of 0.68% moisture over measurements on soybeans of four cultivars from soybean producing areas in the Midwest and the Southeast. Capacitance measurements at 1 and 5 MHz on the same single soybeans, held between and in contact with 2-cm-diameter parallel-plate electrodes, produced moisture content determinations with a standard error of 0.56% moisture content. Thus, both techniques offer comparable accuracies when suitably calibrated. RP NELSON, SO (reprint author), USDA ARS,RICHARD B RUSSELL AGR RES CTR,ATHENS,GA 30613, USA.

Plots of the dielectric constant and loss factor at 41 frequencies between 200 MHz and 20 GHz are illustrated for apple, lemon, carrot, cucumber, and avocado, and condensed data for all, along with moisture content, tissue density, and total soluble solids, are tabulated at six frequencies covering the same range. Although specific values differ, the dielectric constant decreases steadily with increasing frequency, dropping more rapidly at frequencies above 5 GHz. Values for the loss factor decrease as frequency increases above 200 MHz to a broad minimum in the 1- to 3-GHz region and then increase again as the frequency approaches 20 GHz. The dielectric behavior of the fruit and vegetable tissues appears to be influenced by ionic conductivity and bound water relaxations at the lower frequencies and by free water relaxation at the higher end of the frequency range.

This equation, with slight modifications, has been used successfully for predicting moisture contents of small quantities (about 15 to 30 kernels) of popcorn. Measurements of capacitance, dissipation factor and/or phase angle were taken with an impedance analyzer at 1 and 4.5 MHz on a parallel-plate capacitor holding small numbers of kernels between the plates.

Early investigations revealed that many of the common forest shrubs could not withstand vertical force application. Small machines, with appropriate tools can lift these plants, including most of their root system, out of the soil. Because these systems are treating one plant at a time, they are most efficient with stands of larger shrubs. These methods avoid the use of herbicides and are substantially cheaper than the use of hand crews. C1 US FOREST SERV,REDDING,CA.

Technical forestry aspects, including approval of a mandatory management plan, are administered by the Vermont Department of Forests, Parks and Recreation. Our objectives were to use data collected by the Department to estimate the annual timber harvest from lands enrolled in the UVA Tax Program and to explore relationships among management variables and harvest information for individual stands. Overall, 31 percent of UVA properties reported a commercial harvest during 1989. In total, the harvest on enrolled lands represented 18 percent and 24 percent, respectively, of the reported total sawlog and pulpwood-fuelwood harvest in Vermont in 1989, while enrolled lands represented about 16 percent of the total timberland in the State. However, there were no significant relationships among stand and harvest variables that would be useful in predicting harvesting activity. The UVA Tax Program gives the State some influence over forestry activity on privately owned timberland that it did not have prior to the Program.

A total of 6,888,000 acres was harvested; 4,011,600 acres by partial harvest, 219,900 acres by seed tree and shelterwood methods, 2,562,000 acres by clearcut, and 94,500 acres by salvage cut. Of the 2,454,700 acres of clearcut upland forest types, 640,500 acres converted to the oak-hickory type. It is taking 6 to 7 years, after harvesting, for softwoods to reach the 3.0-inch diameter threshold. Additionally, softwood stand volume 13 to 17 years after clearcut harvest is below that expected for normal sites. Low softwood stocking levels and lengthy regeneration lag time are cited as two possible reasons for low yields at this stage of stand development.

There were 1,258,100 acres of upland seedling-sized stands and 1,639,000 acres of upland sapling-sized stands. Forty-six percent of seedling-sized stands and 51 percent of sapling-sized stands originated from plantations. Most of the seedling-sized stands (58 percent) were on nonindustrial private forest (NIPF) lands, along with 50 percent of sapling-sized stands. There were 952,500 acres of seedling-sized stands and 765,800 acres of sapling-sized stands that were <60 percent stocked with softwoods. Seedling- and sapling-sized stands with initially low softwood stocking levels have a higher risk of becoming understocked poletimber and sawtimber stands, especially where conditions (e.g., drought, competition, pests, disease, and/or poor seedling quality) impact mortality rates during the first 15 years of stand development.

The process was based on coregistration of Advanced Very High Resolution Radiometer (AVHRR) data and Landsat Thematic Mapper (TM) data and on regression analysis of statistical relationships between the two data types. A forest density value is the percentage of forested TM cells within one AVHRR cell. The process can be used in other remote sensing projects that involve a primary, inexpensive, data set for total enumeration and a secondary, more accurate data sample. However, this process is ideally suited to AVHRR data whose characteristics (low cost and large area coverage) make the process more meaningful for large area forest mapping applications. Benefits of the forest density mapping procedure, as demonstrated by the project, include providing additional forest land information derived from subpixel measurements, aiding forest type classification, and allowing the study of density distributions of different forest types.

The insecticides carbofuran and diazinon, and the herbicides atrazine and metolachlor were used in the study, which included the incubation and leaching of pesticides from untreated soils and soils in which microorganisms had been inhibited. The mineralization of ring C-14 labeled pesticides was studied. The study differentiated between biotic and abiotic processes that determine the fate of pesticides in the soil. Higher leaching rates of pesticides from PT soils are explaned by the relative importance of each of these processes. In NT soils, higher microbial populations and activity were associated with higher mineralization rates of atrazine, diazinon and carbofuran. Enhanced transformation rates played an important role in minimizing the leaching of metolachlor and carbofuran from NT soils. The role of abiotic adsorption/retention was important in minimizing the leaching of metolachlor, carbofuran and atrazine from NT soils. The role of fungi and bacteria in the biodegradation process was studied by selective inhibition techniques. Synergistic effects between fungi and bacteria in the degradation of atrazine and diazinon were observed. Carbofuran was also degraded in the soils where fungi were selectively inhibited. Possible mechanisms for enhanced biodegradation and decreased mobility of these pesticides in the upper layer of NT soils are discussed. C1 US ARS,NRI,ENVIRONM CHEM LAB,BELTSVILLE,MD 20705.

Little quantitative information exists on the hydrologic response to burn severity. This study compared the effects of low-severity and high-severity burns on runoff and sediment yields during rainfall simulation and during natural rainfall in the Southern Appalachian Mountains. Fire severity was largely determined by moisture conditions of the forest floor prior to ignition. Runoff and sediment yield variability was high between plots within the same treatment area due to differences in forest floor characteristics and infiltration rates. Conditions of high-severity resulted when burning was conducted with relatively dry fuels. Sediment yields were 40-times greater for the high-severity treatment areas than the low-severity treatment areas. C1 CLEMSON UNIV,US FOREST SERV,SE FOREST EXPT STN,CLEMSON,SC 29634.
