Wheat Grain Arabinoxylan Quantification, Characterization, and Fate During Baking
The study of wheat (Triticum aestivum L.) as it relates to end-use quality is highly diverse. This dissertation examines end-use quality across the U.S. and how the non-starch polysaccharide arabinoxylan (AX) influences ...
IDENTIFICATION OF PATHOGENIC RACES AND MICROSATELLITE MARKERS OF TILLETIA CARIES (D.C.) TUL. & C. TUL. AND MAPPING OF A COMMON BUNT RESISTANCE GENE IN WINTER WHEAT
Common bunt, caused by Tilletia caries and T. foetida, is one of the most devastating seedborne diseases of wheat. In conventional agriculture, the disease is managed almost exclusively with chemical seed treatments. ...
FATE AND TRANSPORT OF RADIONUCLIDES [U(VI), Sr, Cs] IN VADOSE ZONE SEDIMENTS AT THE HANFORD SITE
Physical and chemical heterogeneities are inherent in subsurface environments due to varying: mineralogy, pore geometry, solution saturation, and solute concentration. The goals of this research were to study the heterogeneities ...
IDENTIFICATION AND INHERITANCE OF RESISTANCE TO IMIDAZOLINONE HERBICIDES THROUGH INDUCED MUTAGENESIS AND INTERACTIONS BETWEEN RHIZOCTONIA ROOT ROT AND SELECTED HERBICIDES IN BARLEY
Induced mutagenesis can be an effective way to increase variability in crop species. Crop resistance to a given herbicide can be of practical value to control weeds with efficient chemical usage. However, this type of ...
Impacts of nitrogen fertility, soilborne disease, and socioeconomic factors on diverse small grain production systems of the Pacific Northwest
Small grains are grown in rotation with many temperate crops in the Columbia Basin and Puget Sound regions, functioning to improve the profitability of the cash crops. During 2009-10, 45 isolates of
BIOCHAR: ITS CHARACTERIZATION AND UTILITY FOR RECOVERING PHOSPHORUS FROM ANAEROBIC DIGESTED DAIRY EFFLUENT
In pyrolysis, an alternative to petroleum-based energy, the result of low oxygen combustion is a carbon-rich solid commonly called biochar. We evaluated biochars made from four feedstocks regionally available (wood pellets ...
Rotational Cropping Systems for Nitrogen Management and Weed Control in Dryland Organic Wheat Production
Diversification of cropping systems with legumes is a common practice used to overcome soil fertility and weed control challenges in organic farming systems. The current study assessed different legume-intensive cropping ...
UNDERSTANDING AND CHARACTERIZING THE GENES ASSOCIATED WITH RPG1-MEDIATED RESISTANCE PATHWAY AGAINST STEM RUST
Barley stem rust resistance gene, Rpg1 (Reaction to Puccinia graminis 1), confers durable resistance to barley cultivars against stem rust caused by many races of Puccinia graminis f. sp. tritici. The current study was ...
EFFECTS OF GENOTYPE, FERTILIZER, AND MYCORRHIZAL FUNGI ON PHOSPHORUS USE EFFICIENCY OF ORGANIC AND CONVENTIONAL SPRING WHEAT
Recent attention to the increasing environmental and monetary costs of mining dwindling phosphorus (P) reserves have lead to renewed efforts to design agricultural systems that use P more efficiently. The objective of these ...
Statistical Applications in Plant Breeding and Genetics
Statistical analysis has many applications ensuring the validity and reproducibility of plant breeding and genetics research. Crop plant germplasm collections are often too large to be of use regularly. A core subset with ...
