FR‐H3 : a new QTL to assist in the development of fall-sown barley with superior low temperature tolerance

Creator:: Fisk, Scott P.
Abstract:: Fall-sown barley will be increasingly important in the era of climate change due to higher yield potential and efficient use of water resources. Resistance/tolerance to biotic and abiotic stresses will be critical. Low temperature is an abiotic stress of great importance. Resistance to barley stripe rust (incited by Puccinia striifomis...

Mycological Maintenance of Rangelands and the Impacts of a Thatch Forming Invasive Annual Grass (Taeniatherum caput-medusae)

Creator:: Hovland, Matthew
Abstract:: Arbuscular mycorrhizal fungi (AMF) may exert profound influences on ecosystem resilience and invasion resistance in western North American sagebrush steppe and other arid rangeland plant communities. Maintenance of plant community structure through ecological feedbacks such as facilitation of nutrient cycling and uptake by host plants, physical and chemical contributions to...

Differences in Evolutionary History and Ploidy Type Shape the Interactions of Populus tremuloides Michx. with Climate

Creator:: Greer, Burke Thomas
Abstract:: Quaking aspen (Populus tremuloides Michx) is a species with high phenotypic plasticity and a broad distribution that, in the last decade, has experienced climate stress-induced mortality called Sudden Aspen Decline (SAD). In order to help mitigate the effects of SAD in the future, we need a better understanding of aspen’s...

Locally grown alternative feed ingredients in turkey diets

Creator:: Sulaiman, Kurdman Mohammed Ali
Abstract:: In recent years, small poultry producers have been interested in finding an alternative for corn and soybean for a variety of reasons. Health concerns related to either naturally occurring isoflavones (phytoestrogens) or their genetically modified organism (GMO) status are the primary considerations behind this trend. Secondly, the recent high prices...

Improving soil water determination in spatially variable field using fiber optic technology and Bayesian decision theory

Creator:: Sayde, Chadi
Abstract:: Achieving and maintaining sustainability in irrigated agriculture production in the era of rapidly increasing stress on our natural resources require, among other essential actions, optimum control and management of the applied water. Thus, a significant upgrade of the currently available soil water monitoring technologies is needed. The primary goal of...

Soil Water Tension Irrigation Criteria Affects Both Stevia Rebaudiana Leaf Yield and Leaf Steviol Glycoside Composition

Creator:: Parris, Cheryl A.
Abstract:: Stevia (Stevia rebaudiana) is a perennial herbaceous plant native to Paraguay and used traditionally by the native Guarani peoples for centuries to sweeten medicinal teas. Stevia has only been commercially cultivated over the past 50 years and cultural practice information suitable for implementation by growers is limited. Currently stevia’s commercial...

Individual Differences in Retronasal Odor Responsiveness : Effects of Aging and Concurrent Taste

Creator:: Flaherty, Tyler J.
Abstract:: Taste sensitivity has been considered the primary chemosensory factor in studies of chemical senses and ingestive behavior. However, recent research has shown that retronasal olfaction is at least equally important in food preference and selection. Additionally, taste has been shown to modulate perceived intensity of retronasally perceived odors. The objectives...

From the Oregon Wolfe Barley to fall-sown food barley : markers, maps, marker-assisted selection and quantitative trait loci

Creator:: Chutimanitsakun, Yada
Abstract:: Understanding complex traits is a fundamental challenge in plant genetics and a prerequisite for molecular breeding. Tools for trait dissection are markers, maps, and quantitative trait locus (QTL) analysis. Marker-assisted selection (MAS) is an application that integrates these tools. In this thesis research, a new sequence-based marker was evaluated, maps...

Phenotyping diverse strawberry (Fragaria spp.) germplasm for aid in marker- assisted breeding, and marker-trait association for red stele (Phytophthora fragariae) resistance marker Rpf1

Creator:: Mathey, Megan M.
Abstract:: Strawberry is one of four crops included in the USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project along with apple, peach, and cherry. Phenotyping strawberry for specific horticultural and commercial traits is important to identify associations with genotypic marker(s). This process is the first step in translating genomic knowledge into enhanced...

A microcomputer software package for simulation of non-ideal aqueous electrolyte systems at equilibrium

Creator:: Sinquefield, Scott A.
Abstract:: The non-ideal aqueous electrolyte simulator (NAELS) is composed of three major parts: a Newton-Raphson non-linear optimization program written by Weare, et al (1987); an activity coefficient subroutine for non-ideal electrolyte systems based on Pitzer's model; and an extensive, user expandable database. It is robust, stable, and requires neither thermodynamic data...
