Sweet cherry is an important horticultural crop in Washington. Sweet cherry trees are grown as composite plants where the scion is grafted onto a rootstock. Rootstock genotype influences tree yield potential (among other ...

Chemical fumigation disinfestation treatments bring more and more concerns due to its hazard to environment and human health, it is necessary to develop alternative non-chemical disinfestation treatments for agricultural ...

This study analyzed the effects of water stress levels on the yield, quality, water use efficiency and grower returns of drip irrigated native spearmint and four subsurface drip irrigated hop cultivars: Mt. Hood, Columbus, ...

Winter conditions necessitate tolerance of snow mold and freezing cold among winter wheat plants. These traits involve numerous quantitative trait loci (QTL), environmental interactions, and mechanisms such as carbohydrate ...

Oats (Avena sativa L.) are a versatile crop with diverse genetic resources. A study of population structure in a collection of oat genotypes relatively unaffected by recent breeding activity identified an under-utilized ...

How do we, as humans and as scientists, learn about the world around us? In this dissertation, I explore how models--epistemological tools that connect theory and reality--not only structure scientific inquiry (including ...

This dissertation consists of three chapters based on product differentiation and increasing returns to scale. Chapter 1 studies a static monopolistic competition model with social indifference curves over a group of ...

Emerging phenotyping methods and increasingly abundant genotyping platforms have become valuable tools for the discovery and introgression of yield-positive and stress-adaptive genes into modern wheat (Triticum aestivum ...

The commodification of wheat and its ubiquity in food, society and agriculture belies its potential to contribute to the ecology, nutrition and economies of regional food systems. The craft and science of plant breeding ...

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
