Insights into the Host Range, Population Decline, and Pathogenicity to Potato of Globodera ellingtonae

Creator:: Baker, Hannah V.
Abstract:: This thesis project has the following specific objectives: (i) Determine pathogenicity of Globodera ellingtonae to potato utilizing two trials conducted over a 16 week period, (ii) Elucidate the host range of G. ellingtonae using a variety of different Solanum weed species and crop species, and (iii) Characterize population decline of...

Seasonal estimates of nitrogen fixation by Alnus rubra and Ceanothus species in western Oregon forest ecosystems

Creator:: Kim, Dong Yeob
Abstract:: Two case studies of 5 ecosystems were used to examine the nitrogen fixation rate of red alder (Alnus rubra Bong.), varnishleaf (Ceanothus velutinus var. laevigatus (Hook.) T. & G.), deerbrush (C. i ntegerrimus H. & A.), and snowbrush (C. velutinus var. velutinus Dougl. Ex Hook). The first case study assayed...

Fluorimetric analysis of intracellular calcium in high and low mobility fowl sperm

Creator:: Olson, Jill Wardell
Abstract:: Sperm mobility is defined as the net movement of a sperm population against resistance. Previous research demonstrated that the cell-permeant Ca2+ indicator rhod-2 AM gave a fluorescent signal predominantly in the head region of fowl sperm that differed between sperm mobility phenotypes. This thesis served to explore the role of...

Comparative Genomics of Different Races of Columbia Root-knot Nematode and Development of Molecular Markers Linked to Corky Ringspot Resistance in Potato

Creator:: Hu, Shengwei
Abstract:: On a global scale, potato (Solanum tuberosum L.) plays an important role in tackling the threat of food insecurity due to its high yield and broad global acceptance. However, pathogens threaten potato production, causing direct yield loss and rendering potatoes tubers unmarketable. Breeding new cultivars that carry multiple resistances is...

Rheological and spectroscopic characterization of surimi under various comminuting and heating conditions

Creator:: Poowakanjana, Samanan
Abstract:: Optimization of comminuting and heating conditions for surimi gel preparation obtained from three fish species: Alaska pollock (AP) (Theragra chalcogramma), Pacific whiting (PW) (Merluccius productus), and threadfin bream (TB) (Nemipterus spp.) was the focus of this study. Three parameters during comminution were separately evaluated: chopping time, chopping temperature, and salting...

Attractivity of plant volatiles and a semichemical-based bait to the western spotted cucumber beetle, Diabrotica undecimpunctata Mannerheim (Coleoptera: Chrysomelidae)

Creator:: Hongtrakul, Tawatchai
Abstract:: The adult western spotted cucumber beetle (WSCB), Diabrotica undecimpunctata undecimpunctata Mannerheim is considered a major pest of snap beans grown for processing in Western Oregon. Control consists of 1 or 2 insecticide sprays prior to harvest. A commercial semiochemical-based insecticide bait, Adios TIC®, 1.3% carbaryl + 5% buffalo gourd root...

Three essays on international trade and regional productivity

Creator:: Moon, Hanpil
Abstract:: A firm's productivity is composed of two parts: pure technical change and location-specific (agglomeration) externalities. Regional productivity is thus an aggregation of productivity of firms producing similar goods and located in a given region. International trade can affect both components of regional productivity. First, trade openness in a closed economy...

Essays on land-use change, carbon sequestration and emissions in China

Creator:: Li, Man
Abstract:: China has experienced rapid economic growth in the last twenty years, accompanied by large-scale land conversion, severe environmental degradation, and rising carbon dioxide (CO₂) emissions. Designing policies for sustainable development requires a comprehensive understanding of the relationship between economic growth, land-use change, carbon sequestration and emissions in China. This dissertation...

Production of SO₂ and SO₂ binding compounds by Saccharomyces cerevisiae during the alcoholic fermentation and the impact on wine lactic acid bacteria

Creator:: O'Neil, Allison L.
Abstract:: Malolactic fermentation (MLF) is important in the production of wines as it reduces acidity through the conversion of malic acid to lactic acid. However, successful MLF can be difficult to achieve due to yeast antagonism of the bacterium responsible for the secondary fermentation, Oenococcus oeni. In particular, yeast produced sulfur...

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...
