Breeding qualitative and quantitative traits for potatoes in the Columbia Basin

Creator:: Graebner, Ryan C.
Abstract:: The cultivated potato (Solanum tuberosum L.) is one of the world’s most important staple crops, ranked fourth after maize, rice, and wheat. While the potato’s success is due largely to its high yield, it also benefits from its broad global acceptance, and its ability to be used by the consumer...

Physiological, Chemical and Genetic Studies in Meadowfoam (Limnanthes alba)

Creator:: Zhang, Jun
Abstract:: Meadowfoam (Limnanthes alba) is an oilseed crop with unique chemical characteristics. The ability to identify physiological maturity (PM) and harvest maturity HM of the crop would permit timely harvest of high quality seeds. However, changes of oil contents, fatty acid profile and glucosinolate contents, as well as seed quality during...

Response of Roughstalk Bluegrass (Poa trivialis L.) to Waterlogging Stress

Creator:: Liu, Mingyang
Abstract:: Roughstalk bluegrass (Poa trivialis L.) (RB) is a weed species that increased very quickly in grass seed production fields of the Willamette Valley. The invasion of RB in grass seed crops often occurs in waterlogged soils. In waterlogged areas, RB exhibited better competitiveness and had greater population densities than other...

Effect of Plant Growth Regulator and Irrigation on Physiological and Harvest Maturity of Red Clover in Relation to Seed Quality

Creator:: Angsumalee, Duangporn
Abstract:: Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...

Identifying the Parameters for Wheat Pollen Electroporation Transformation

Creator:: Liu, Jiang
Abstract:: Wheat (Triticum aestivum L.) is one of the most important crops in the world. It has been and continues to be one of the main sources of food for humans and animals. Although traditional wheat breeding has contributed greatly to the improvement of wheat both in productivity and biotic/abiotic stress...

Improving the Forage Species Selection Process through Research and Teaching Projects

Creator:: Randow, Brianna Lyn
Abstract:: Species selection is a complex process that forage producers and land managers face. Accurate tools and educational materials are needed to help make the decision process easier. Crop simulation models are one tool that could be utilized to predict yield and potential financial return of various species. Two crop simulation...

Spring nitrogen and cultivar effects on winter canola (Brassica napus L.) production in western Oregon

Creator:: Ferguson, Brock T.
Abstract:: Limited information is available on the effects of applied spring nitrogen (N) and cultivar on winter canola (Brassica napus L.) production in high-rainfall environments. The objectives of this investigation were: (i) to determine the effects of spring N and winter canola cultivars on seed and oil production characteristics, and (ii)...

A historical evaluation of high molecular weight glutenins and the dwarfing (Rht) gene in Triticum aestivum in selected genotypes grown in the United States

Creator:: Roseborough, Colleen
Abstract:: Wheat (Triticum aestivum) is an important crop worldwide, however, in recent years concerns have been raised regarding two health issues, celiac disease and gluten sensitivity, and their relationship to wheat consumption. This increase has led to questions regarding potential changes over time in the composition of gluten (glutenin and gliadin)...

Bioherbicide use of plant defensive compounds in meadowfoam seed meal

Creator:: Intanon, Suphannika
Abstract:: Meadowfoam (Limnanthes alba Hartw. ex Benth) seed meal (MSM), a by-product of meadowfoam oil extraction, has a plant defensive compound known as glucosinolate glucolimnanthin (GLN). Myrosinase enzymes present in soil microbes and meadowfoam seeds can convert GLN to glucosinolate breakdown products (GBPs), which demonstrate herbicidal activity and have the potential...

Multiple-resistant Italian ryegrass (Lolium perenne spp. multiflorum) populations in Oregon

Creator:: Liu, Mingyang
Abstract:: Italian ryegrass (Lolium perenne spp. multiflorum) is a common weed management problem in turfgrasses, cereals and non-crop areas in the United States. In Oregon, the number of populations with multiple-resistance continues to increase. To manage these resistant populations, the resistance patterns must be determined. In this study, five Italian ryegrass...
