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...

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...

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...

Descriptive sensory analysis of thornless blackberry selections to determine sensory similarity to 'Marion' blackberry flavor

Creator:: Kurnianta, Astrid Joana
Abstract:: 'Marion' blackberry is known for having excellent aroma and flavor, yet they are susceptible to damage by freezing and they are very thorny. Thornless blackberry cultivars have been developed and show great potential. Thus, the interest of the study was in determining which of eight thornless blackberry cultivars, have similar...

Biology and management of the obliquebanded leafroller, Choristoneura rosaceana (Harris) (Lepidoptera: Tortricidae), in sweet cherry

Creator:: Omeg, Michael Kent
Abstract:: The seasonal biology of the obliquebanded leafroller, Choristoneura rosaceana (Harris), was studied to improve its management in Mid-Columbia area sweet cherry orchards. Overwintering OBLR larvae began to emerge from hibernacula at bud stage 2 (side green). Most overwintering larvae emerged from hibernacula within three weeks of first bud swell and...

A study of demand and supply relationships in the agricultural labor market

Creator:: Vathana, Chamnong
Abstract:: The objective of the study is to analyze empirically the demand for hired farm labor and the elasticities of substitution of capital for labor in the U.S., the Middle Atlantic region, the Pacific region, and in the states of California and Oregon. The data period 1941-1969 was analyzed for the...
