Compensating effects and gene action estimates for the components of grain yield in winter wheat (Triticum aestivum, L. em Thell)

Creator:: Abi-Antoun, Michel
Abstract:: Five winter wheat cultivars and their diallel crosses were evaluated for plant height, harvest index, deading-maturity duration, the components of yield, (spikes per plant, spikelets per spike, kernel weight and kernels per spikelet)and total plant yield. Two diverse locations, Moro, a dryland site (250 mm annually) located in central Oregon...

Heritability for perloline, nitrogen, and digestibility characteristics in tall fescue (Festuca arundinacea, Schreb.) single-crosses grown in two locations

Creator:: Watson, Clarence Ellis
Abstract:: Tall fescue often results in poor liveweight gains. This may be accounted for by variations in perloline content, nitrogen content, or digestibility of the plant. Two groups of tall fescue plants were examined for each of these traits. These groups consisted of (a) fifteen single-crosses of a six parent diallel...

Pathogenicity of experimentally induced concurrent infections of Fasciola hepatica and Haemonchus contortus in sheep

Creator:: Presidente, Paul J.
Abstract:: Twenty yearling sheep were allotted to four groups, each containing five sheep of approximately equal weight. On experimental days 0, 1, 2, 3, and 4, each sheep in each group was given the following inoculations by stomach tube: five sheep in group I (Fasciola hepatica-exposed controls) were given approximately 120...

Geochemical cycling in a Pacific Northwest estuary (Tillamook Bay, Oregon, USA)

Creator:: Colbert, Debbie L.
Abstract:: This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...

Genotype-environment interaction in winter wheat F₁ progeny

Creator:: Peterson, C. J.
Abstract:: Seven winter wheats were evaluated for plant height, the components of yield and yield in a diallel cross at Pendleton, Oregon and Lind, Washington. An additional parent was added to the diallel cross at Pullman, Washington. Two levels of nitrogen and five replications were utilized at each of the locations....

Investigations of T cell costimulation and autoimmunity in mice, and development of flow cytometric methods to assess lymphocyte stimulation in dogs

Creator:: Weatherill, Amy R.
Abstract:: Proper immune function is indispensable, as failure to mount an immune response against a pathogen can lead to serious complications or even death. T cells act by enhancing the activation of phagocytic cells as well as the activation of B cells. Their widespread influence on an immune response makes optimal...

Phylogeography, evolution, and conservation in forest-associated Pacific Northwest salamanders

Creator:: Wagner, R. Steven
Abstract:: Phylogeographic studies of six Pacific Northwest forest-associated salamanders provide insight into historical and contemporary processes on population genetic structure. Among Larch Mountain Salamanders (Plethodon larselli), cytochrome b mitochondrial (mtDNA) sequences (381 bp) and random amplified polymorphic DNA (RAPDs; 34 loci) supported separate Management Units for northern and southern populations (12...

Evaluation of behavioral response of Aedes aegypti mosquitoes to repellents using a novel olfactometer

Creator:: Doğan, Elif Barc̦in
Abstract:: Mosquito-borne pathogens are the cause of important, often deadly diseases worldwide; and, use of repellents is one of the components of mosquito control programs. The most effective mosquito repellent is N,N-dimethyl-m-toluamide, known as DEET. Speculation on the adverse effects of DEET have been on the rise since the 1980s, and...

Impaired organic anion excretion and cholestasis caused by 1,3-bis-(2-chloroethyl)-1-nitrosourea (carmustine or BCNU) in rats

Creator:: Hoyt, Dale G.
Abstract:: Previous investigation showed that 20 mg/kg BCNU caused inhibition of sulfobromophthalein (BSP) excretion and inhibited bile salt independent bile flow (BSIF) in rats by 48 h after treatment (Hoyt, 1984). The present investigation demonstrated that BCNU inhibited the canalicular step in the excretion of BSP. This was indicated by the...

Plasma membrane composition and luteinizing hormone receptors of ovine corpora lutea during early pregnancy

Creator:: Zelinski, Mary Beth
Abstract:: The lipid composition of plasma membranes of corpora lutea was examined to determine whether changes in this organelle occur during regression and early pregnancy in the ewe. Forty ewes were assigned to be necropsied on days 13 or 15 of the estrous cycle (D13-NP and D15-NP) or pregnancy (D13-P and...
