The Distribution And Morphology Of Fucus Distichus In An Estuarine Environment And The Effect Of Selected Ions On The Uptake Of Inorganic Carbon And Nitrate, Dale Howard Robinson

Dissertations and Theses

The morphology, distribution, and habitat of dwarf and normal forms of Fucus distichus in Nehalem Bay were examined. The dwarf form lacked the holdfast and sexual structures of the normal form and was more highly branched. Examples of the dwarf form were found growing as outgrowths of fragmented normal forms indicating that both forms are the same species. The normal form occurred attached to rocks near the mouth of the bay in waters of oceanic salinity. The dwarf form occurred as a free-living form in the salt marshes and in waters of lower salinity. These observations suggested that the occurrence …

Biosynthesis And Degradation Of Storage Protein In Spores Of The Fungus Botryodiplodia Theobromae, Gary Petersen, Kurt Dahlberg, James L. Van Etten

Department of Plant Pathology: Faculty Publications

Muiridin, a spore-specific protein of the fungus Botryodiplodia theobromae, comprises about 25% of the mature pycnidiospore protein. It has an apparent molecular weight of 16,000 to 17,000 and is rich in glutamine, asparagine, and arginink. Muiridin is synthesized in developing spores via a precursor with an apparent molecular welght of 24,000. Two other polypeptides present in young developing spores with apparent molecular weights of 18,000 and 15,000 are immunologically related to muiridin. We propose a pathway for muiridin synthesis. Muiridin is actively degraded during the germination of spores from 30-day old cultures. This degradation is independent of exogenous amino …

The Effect Of Hurricane Allen On The Near-Shore Vegetation Of South Padre Island, Frank W. Judd, Sammie L. Sides

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

The effect of Hurricane Allen (Aug. 10, 1980) on the near-shore vegetation of South Padre Island was assessed by comparing data obtained in line transects before and after the hurricane. Eight species of plants were present in the Backshore Zone prior to the hurricane; after the hurricane, only three species were present and percent cover was only 11% of that before the hurricane. The foredunes of this zone were completely leveled and a belt of Sesuvium portulacastrum was obliterated. Conversely, plants of the taller Primary Dune Zone were not greatly disturbed by the hurricane. Numbers of species and percent cover …

Urease Activity In A Kentucky Bluegrass Turf, W. A. Torello, David J. Wehner

Office of the Dean (CAFES) Scholarship

The components of a turfgrass ecosystem, including plants, an intervening layer of thatch and the underlying soil, influence the fate of topically applied urea fertilizer. The loss of urea N by ammonia volatilization may be governed by the rate of urea hydrolysis. The main objective of this study was to determine the extent of urease activity associated with turfgrass plant tissue, thatch, and the underlying soil. This information may help elucidate the mechanism of ammonia loss following urea application. Because a turfgrass stand frequently possesses an extensive thatch layer that may serve as the primary plant growth medium, additional objectives …

Jamaican Blue-Green Algae Collections Of J.C. Strickland, W. John Hayden

Biology Faculty Publications

Professor John C. Strickland (1915-1980) devoted much of his life to teaching biology, botany, and phycology at the University of Richmond. Throughout his academic career he maintained a keen interest in the Myxophyceae, or blue-green algae, studying their culture, cytology, and taxonomy (Drouet & Strickland, 1942; Strickland, 1940, 1946). Most of his collections of these and other algae were made in Virginia and are housed in the herbarium maintained by the Department of Biology, University of Richmond. However, he also made four trips to Jamaica in the years 1966-1971 before his health deteriorated to the extent that field work, and …

Day-Degree Methods For Pest Management, Kenneth P. Pruess

Department of Entomology: Faculty Publications

Recommendations are made for reporting day-degree methods which may have practical applications. Standardized thresholds (40, 50, and 60°F, or 5, 10, and 15°C) should be used. Day-degrees may be either sine wave approximations or exact units determined by instrumentation. Methods are proposed for converting current day-degree models to standardized thresholds and, ultimately, to actual day-degrees.

The Combined Effect Of Cu And Zn On Selenastrum Capricornutum, Helmer Colonia-Roque

Dissertations and Theses

It has been demonstrated that the toxicity of heavy metals depends on their chemical speciation and can be related to their free ion activities, rather than the total metal concentrations. The objective of this study was to determine the effect of combined free ions of zinc and copper on the toxicity to the green alga Selenastrum capricornutum. This alga was grown in a defined medium, under controlled laboratory conditions, with a varying range of zinc and copper concentrations. The growth rate of the alga was inhibited at pZn = 5.93 or at pCu = 7.24. The results suggest that …

The Effects Of So2 On N2-Fixation, Carbon Partitioning, And Yield Components In Snapbean, Phaseolus Vulgaris L., Stephen M. Griffith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary air pollutant sulfur dioxide has been shown to affect plant biochemistry and physiology, although very little is known about its effects on N₂-fixation in legumes.

This study was designed to determine if N₂-fixation, carbon partitioning , and productivity are affected under short term low level, so₂ exposures.

Greenhouse grown snapbeans (Phaseolus vulgaris L. cv. Earliwax), 29 days from planting, were exposed to 0.0, 0.4, and 0.8 parts per million sulfur dioxide for 4 hours day^-1 for 5 days in a fumigation chamber. At these concentrations there was no visible damage of …

Plant Responses To Clinostating And Mechanical Stress: Growth And Flowering Responses, Chauncy Steed Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Plants rotated about a horizontal axis show certain growth responses. This research was designed to clarify which of the responses of clinostating are caused by gravity compensation and which are caused by mechanical stresses. Plants used were Xanthium strumarium L. (cocklebur) Chicago strain and Lycopersicon esculentum Mill. (tomato) cv. Rutgers. Six automated treatments that ran for five days were used to separate out the effects. Treatments were: 1) controls, 2) horizontal clinostat, 3) intermittent clinostat, 4) inversion (every 10 min), 5) invert and return, and 6) vertical rotation. Plant height and diameter changes were measured at ink dots with a …

Development And Pathogenicity Of The False Root-Knot Nematode Nacobbus Aberrans And Its Relationship With Heterodera Schachtii And Meloidogyne Hapla On Sugarbeet, Renato Nunzio Inserra

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Duration of embryogenic development of a Nebraska population of Nacobbus aberrans at 15 and 25 C were 51 and 9-10 days respectively. The first juvenile (J1) molted in the egg and the nematode emerged as J2. Kochia and sugarbeet root leachates did not significantly affect the percent of cumulative egg hatch. Temperature significantly affected juvenile emergence (P= 0.05), as less than 1, 5, and 20% of the eggs hatched at 5, 10 and 15 C, respectively. More than 70% of the eggs hatched at 20 and 25 C. At 25 C, postembryogenic development from egg to egg was …

The Photoregulation Of Phenylpropanoid Metabolism And Amino Acid Accumulation In Triticum Aestivum (Var. Fremont), Daniel J. Guerra

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wheat (Triticum aestivum L.) grown in controlled environments with a 24-hour photoperiod was analyzed for phenylpropanoid and amino acid metabolites. Discrete spectral environments, including a metal halide, high-pressure sodium and low-pressure sodium lamps, provided both photosynthetically active radiation and phenylpropanoid inducing fluences of light. A greenhouse spectral environment supplemented with fluorescent lamps was also used to culture wheat. All four spectral environments were used to culture wheat to maturity separately. The activities of phenylalanine and tyrosine ammonia-lyase were photoinduced in wheat tissue obtained from plants grown in the metal halide, high-pressure sodium and greenhouse spectral environments. These enzyme activities are …

The Effect Of Indoleacetic Acid And Related Chemicals On Growth Patterns Of Decapitated Bean Plants, Lewis V. Buchanan

Masters Theses

Bean plants were used to study effects of IAA and related chemicals on plant growth patterns. Plant apical growth tips were removed, eliminating apical donimance. Decapitated plants were treated in experimental groups with IAA, tryptophan, 5-hydroxy indoleacetic acid, serotonin, and melatonin. Two other groups served as controls, one cut, and one uncut.

Growth measurements were taken to determine if the treatments could effectively restore apical dominance. Cut control plants showed a loss of apical dominance, with decreased apical growth, and release of inhibition of axillary growth, when compared to the uncut group.

Tryptophan and meltonin treatments restored little or no …

Variability For Traits Used To Estimate Silage Quality In Forage Sorghum Hybrids, Jeffrey F. Pedersen, Francis A. Haskins, H. J. Gorz, R. Britton

Department of Agronomy and Horticulture: Faculty Publications

The variation among 49 F₁ forage sorghum [Sorghum bicolor (L.) Moench.] hybrids from a 7 X 7 cross-classified design was explored in 1979 and 1980 for the following silage traits: dry matter (DM), crude protein, in vitro dry matter disappearance (IVDMD), neutral detergent fiber, acid detergent fiber, acid detergent lignin, ammonia, lactate, and Brix of the juice from fresh stalks. Wider ranges generally were found for male than for female parental means. Means for most traits were significantly different among entries. Significant differences among hybrid means over males and over females were found for only DM, IVDMD, and …

Comparison Of Old Field Succession On A Tallgrass Prairie And A Nebraska Sandhills Prairie, Mary Bomberger Brown, Shelly L. Shields, A. Tyrone Harrsion, Kathleen H. Keeler

School of Biological Sciences: Faculty Publications

Long held to be reasonably well understood, the process of ecological succession has recently come under attack. The predictability of successional changes has been doubted (Walker 1970), the mechanism of species replacement has been questioned (Connell and Slatyer 1977), and the reality of steady-state (climax) challenged (Botkin and Sobel 1975, Connell and Slatyer 1977, Connell 1978). In particular, several communities are presently recognized as having "cyclic succession" (Ricklefs 1973), in which the process is continually repeating. Such communities include heaths (Watt 1947), prairie pot-hole marshes (Vander Valk and Davis 1978), spruce-fir forests (Sprugel 1976, Sprugel and Bormann 1981), and intertidal …

Kentucky's Ipm Program For Alfalfa, Chris M. Christensen

Kentucky Alfalfa and Stored Forage Conference

Integrated Pest Management (IPM) is a concept that encourages the use of a variety of strategies in the management of crop pests. It is very important to have an indepth understanding of the crop production system when implementing an IPM program. An IPM program is dynamic requiring a continual evaluation of the status of the crop, the associated pest complex, the effects of the pests and the biological deterrents to those pests. If a pest population gets "out of hand" and begins to cause economic damage, pest management techniques may need to be applied. These pest management measures may be …

Combining Ability Effects For Forage Residue Traits In Grain Sorghum Hybrids, W. M. Ross, H. J. Gorz, Francis A. Haskins, G. H. Hookstra, J. K. Rutto, R. Ritter

Department of Agronomy and Horticulture: Faculty Publications

Combining ability effects of 10 female and 10 male inbred lines were evaluated for agronomic, grain, and forage residue traits in 100 grain sorghum [Sorghum bicolor (L.) Moench] F₁ hybrids for 2 years. Traits studied were height, flowering, tillering, seed weight, yield, protein percentage, protein yield of grain, leaves, and stems; and in vitro dry matter disappearance (IVDMD) percentage and digestible dry matter (DDM) yield of leaves and stems. General combining ability (GCA) effects exceeded specific combining ability (SCA) effects for all traits except height in females and grain and leaf yields in males. Both GCA and SCA …

Life History Of The Lahontan Cutthroat Trout, Salmo Clarki Henshawi, In Pyramid Lake, Nevada, William F. Sigler, William T. Helm, Paul A. Kucera, Steven Vigg, Gar W. Workman

Great Basin Naturalist

The Pyramid Lake Lahontan cutthroat trout (Salmo clarki henshawi) population was sampled on a monthly basis from November 1975 through December 1977. A subsample of 676 trout, stratified by fish size and lake habitat, provided biological data. The entire population is presently derived from hatchery production, stocked at lengths of approximately 75 to 300 mm. Peak annulus formation occurs in March and April, followed by the period of maximum growth. Scale patterns illustrate a variable growing season. Maximum growth in length is in the first three years of life; after that males begin to grow faster than females. …
