Dinitroaniline-herbicide resistance in goosegrass (Eleusine indica) : ecophysiological aspects

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

Microbial analysis of coniferous forest and nursery soils : effects of ectomycorrhizae, volatiles, and humic-rich organic substrates

Creator:: Schisler, David Albert
Abstract:: Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Microbiological control of food spoilage and pathogenic microorganisms in refrigerated foods

Creator:: Al-Zoreky, Nageb
Abstract:: Microgard, a commercially-available pasteurized fermented milk, was found inhibitory to gram negative bacteria such as Pseudomonas putida, some well-known foodborne pathogens (e.g. Salmonella, Yersinia and Aeromonas) and some fungi as revealed by an agar incorporation assay method. Gram positive bacteria, however, were not inhibited. Rather, some bacteria in this group...

Biology, epidemiology, and biological and chemical control of Phytophthora vignae

Creator:: Fernando, W. Gerard Dilantha
Abstract:: Phytophthora vignae, causal agent of stem and root rot of cowpea (Vigna unguiculata), was reported for the first time in Sri Lanka. The pathogen was found in cowpea field soils from 3 of 5 geographic regions sampled. Only one site however, had plants exhibiting disease symptoms. Of the eight cowpea...

Proteolytic maturation of vaccinia virus structural proteins

Creator:: VanSlyke, Judy K.
Abstract:: Vaccinia virus (VV) is a large DNA virus belonging to the Orthopoxvirus family. The viral replicative life cycle takes place solely within the cytoplasm of a mammalian host cell. The VV genome contains 196 open reading frames which are expressed in a highly regulated and temporal fashion in order to...

Remediation of atrazine in irrigation runoff by a constructed wetland

Creator:: Runes, Heather B.
Abstract:: Due to its frequent use in agriculture and its frequent detection in surface water, atrazine was chosen as a model compound to study the treatment capability of a surface flow wetland used to remediate irrigation runoff at a container nursery near Portland, Oregon. Further evaluation of treatment of atrazine was...

Determinants of microbial community structure and substrate utilization potential in soils of vegetable cropping systems

Creator:: Schutter, Mary E.
Abstract:: The Oregon Long-Term Soil Quality Project was initiated to identify soil properties that respond rapidly to alternative management practices. Such practices included winter cover cropping, which was implemented at two experimental research stations and several grower fields throughout the Willamette Valley. The goal of this thesis was to identify the...
