Resource Type:: Undergraduate Thesis

Measurement of relative fitness of dicarboximide-resistant botrytis cinerea in strawberry leaves

Creator:: Glass, Jenny
Abstract:: Leaves of healthy strawberry plants were inoculated with either vinclozolin-sensitive or vinclozolin-resistant isolates of Botrytis cinerea at one of three concentrations: 5x104, 1x105, and 5x105 conidia/ml. One week following inoculation, representative leaves were harvested and cut into 9mm2 leaf pieces. Some pieces were immediately plated onto selective Botrytis medium while...

A screening method for the essential oils in hops using solid-phase microextraction

Creator:: Heider, Chris
Abstract:: Separation and isolation of organic analytes from environmental matrices such as soils, water, plant, or animal tissue has traditionally involved the use of liquid solvent extractions. Solvent-based extraction methods are often time-consuming, difficult to automate, and use expensive solvents that generate hazardous waste and working conditions. The need for a...

Quantitative determination of DCPA and its metabolites using strong anion exchange solid-phase extraction with gas chromatography/electron capture detection

Creator:: Monohan, Keith
Abstract:: Rapid and accurate analytical methods are needed to assess the impacts of agricultural chemicals on soil and water resources. Solid-phase extraction (SPE) was evaluated as an alternative method to conventional liquid-liquid extraction for the quantitative analysis of the herbicide DCPA and its metabolites in ground waters. Strong anion exchange (SAX)...

A comparison of the theoretical and practical components of the US and German higher-education systems; what we can learn from the German approach to better prepare our students for ever-changing technologies

Creator:: Brownell, Eugene Baars
Abstract:: The curriculum of technical degrees at higher education institutions in the United States needs to continuously adapt to ever changing technologies. One way to accomplish this is to adopt a more dynamic approach that separates the practical and theoretical components of the university education, and where the student concentrates on...

Microbial degradation of linear alkylbenzenesulfonates in sewage contaminated groundwater

Creator:: Eby, Sean D.
Abstract:: Surfactants, or surface active agents, are the active ingredients in detergents used for domestic cleaning applications, such as dish washing and laundering. They are effective cleaning agents by concentrating at interfacial regions, lowering the surface tension of water, and forming micelles that solubilize oils (West, 1992). Surfactants are amphiphilic, because...

Development and evaluation of conservation tillage for squash in Western Oregon

Creator:: Reich, Brandon M.
Abstract:: Squash varieties of Golden Delicious and Squash Hybrid NK 530 were grown in disk-till, strip-till, and no-till conservation tillage systems following a cover crop of'Monida' oats (Avena sativa L.) and common vetch (Vicia sativa L.). Tillage systems were evaluated for effects on squash emergence and yield, weed density and biomass,...

A reassessment of the linkage of red leaf trait and incompatibility loci in hazelnut (Corylus avellana L.)

Creator:: Horton, G.
Abstract:: As in other species, it is possible that a homozygous red leafed (= redleaf) hazelnut (Corylus avellana L.) tree would have brighter red coloration than a heterozygote and thus be more desirable as an ornamental. However, 'Fusco Rubra' and `Rode Zeller' both carry incompatibility allele S6 (thus cross-incompatible) and are...
