Vernalization requirement studies with Pacific Northwest wheats

Creator:: Baloch, Dost M.
Abstract:: Vernalization plays a fundamental role in the adaptation of winter cereals to their growing environment by controlling their growth habit, thereby allowing them to escape cold injury. Because of the climatic conditions of the region, dry summers and wet winters, growers sometimes cannot plant all of their winter wheat in...

Functional profiles of soil microbial communities in second-growth Douglas-fir forests of the Pacific Northwest

Creator:: McGinnis, Megan L.
Abstract:: Forests are one of the largest repositories of terrestrial C. Understanding factors that drive organic matter transformations and nutrient efflux from these systems is therefore highly important. Temperate forests are of particular significance due to the large fraction of C that is stored below ground in the soil. Characterizing nutrient...

A comparative analysis of stream response to disturbance in the Pacific Northwest

Creator:: Hodgins-Carlson, Terry Anne
Abstract:: Published literature about six Pacific Northwest stream systems was contrasted to provide a regional perspective on channel response to disturbance. This investigation was prompted by a combination of recent environmental legislation, mounting social pressures to plan projects at a drainage basin scale, and the difficulty in defining and predicting the...

Genetic variability for kernel hardness in two soft winter wheat (Triticum aestivum L.) cultivators

Creator:: Albahouh, Muhammed S.
Abstract:: To remain competitive in the international marketplace, soft white wheat cultivars grown in the Pacific Northwest must have consistent and predictable flour properties including kernel texture. As a consequence, there is a need to develop wheat cultivars for specific end uses. Wheat cultivars with very soft kernels are used largely...

Growth and development of spring grain species as affected by planting date

Creator:: Armah-Agyeman, Grace
Abstract:: Changes in the federal farm program, in rainfall pattern and quantity, and increased incidence of herbicide resistant weeds and diseases have generated increased interest in spring grains in the Pacific Northwest. However, spring grains have traditionally been treated as minor crops in this region, thus little research has been done...

Germplasm design, gene discovery, and variety release: breeding barley for the Pacific Northwest

Creator:: Graebner, Ryan C.
Abstract:: This thesis consists of three manuscripts addressing separate components of barley breeding, plus an introduction and a conclusion summarizing the status of barley in the Pacific Northwest, plus the implications of the research presented in this thesis. In the first manuscript, a package written for the statistical software "R" that...

Nitrogen mineralization from organic amendments during the second year following application

Creator:: Kusonwiriyawong, Charirat
Abstract:: Estimates of nitrogen (N) available from long-term application of organic amendments are required to balance N inputs with crop N requirements. Two studies were conducted to (1) determine N mineralized from organic amendments (manures and composts) during year 2 after application, and (2) compare plant-available N (PAN) determined via in...

Expansion of scouringrush (Equisetum spp. L.) : crop interference and control options in winter wheat (Triticum aestivum L.) and chemical fallow cropping cropping systems

Creator:: Kerbs, Blake D.
Abstract:: Scouringrushes (Equisetum hyemale L.; E. xferrissii Clute; E. laevigatum L.) are ancient perennial seedless vascular plants historically associated with wetlands, low-lying roadsides or field margins with more plant available water. There has been little research conducted on scouringrush species in the context of agricultural production because traditional farming practices confined...

Estimating the dry matter production, nitrogen requirements, and yield of organic farm-grown potatoes

Creator:: McQueen, John Paul Gainer
Abstract:: As part of a participatory research project, where farmers and Oregon State University researchers collaborated, aspects of potato (Solanum tuberosum L.) growing systems were studied. It was determined through conversations with the farmers that quantification of certain growth parameters of potato was lacking, including dry matter accumulation, crop nitrogen (N)...

Changes in grain quality and grain protein composition of winter wheat cultivars under different levels of soil nitrogen and water stress

Creator:: Saint Pierre, Carolina
Abstract:: Hard white winter (HVVW) wheat cultivars must have superior protein quality and consistent processing quality to be successful in the Asian market. New cultivars and management strategies are needed to produce HVVW grain for both bread and noodle applications from diverse environments in the US Pacific Northwest (PNW). This study...
