Age, chemistry, and tectonic significance of Easter and Sala y Gomez Islands

Creator:: Clark, James Gregory, 1948-
Abstract:: Easter Island and Sala y Gomez are part of the Sala y Gomez Ridge, a broad band of high topography and scattered seamounts extending ESE from the East Pacific Rise. It has been proposed that the Sala y Gomez Ridge results from the movement of the Nazca Plate over a...

Chemically induced pollen supression and subsequent natural outcrossing in selected wheat cultivars (Tritcum aestivum L. en Thell)

Creator:: Lewis, Hal A.
Abstract:: Effective chemical control of pollination would provide an alternative to the cytoplasmic male-sterile system in hybrid wheat (Triticum aestivum L.) production. The objective of this study was to determine concentration, formulation, growth stage of application and genotypic effects on levels of induced pollen suppression and subsequent natural out-crossing from foliar...

Use of Platelet Rich Plasma for the Treatment of Subclinical Endometritis in Beef Heifers

Creator:: Puttman, Elizabeth A.
Abstract:: Postpartum uterine inflammation (endometritis) is not uncommon in beef cattle, resulting in infertility and culling. Prolonged calving may contribute to the increased incidence of endometritis in heifers. Commonly used methods to treat endometritis in beef cattle include intrauterine antibiotics and/or hormone injections, which can result in meat residues. Platelet rich...

Willamette and associated soils on late Pleistocene geomorphic surfaces, Polk County, Oregon

Creator:: Gelderman, Frederick W.
Abstract:: The morphology and genesis of soils of the Willamette series and of some Willamette-associated soils and their relationships to geomorphic surfaces were studied in an area near McCoy, Polk County, Oregon. Influences of regional extent, such as climate and parent material, were related to the soils and landforms. The soils...

Evaluation of hill plots and near infrared reflectance techniques as breeding tools in spring malting barley

Creator:: Tragoonrung, Somvong
Abstract:: Hill plots and near infrared reflectance (NIR) spectroscopy were investigated as breeding tools to facilitate doubled haploid recurrent selection for malting quality characters in spring barley. Main objectives of this research were to i) compare hill and row plot expression of agronomic and malting quality traits in an array of...

Use of wetlands in the Tulare Lake Basin by wintering ducks

Creator:: Coe, Holly N.
Abstract:: I evaluated the use of various wetlands by wintering ducks in the Tulare Lake Basin (TLB), California, during October 1982 - April 1983 and September 1983 - March 1984. Aerial waterfowl counts of the TLB were used to document spacial use patterns by ducks. Ground surveys on evaporation ponds in...

Enzyme-Mediated Conversion of Glucolimnanthin to Bioherbicidal Breakdown Products

Creator:: Bratton, Daniel
Abstract:: The oilseed crop Limnanthes alba (white meadowfoam) is grown in Oregon. Methods were developed for the production of a liquid-based bioherbicide from meadowfoam seed meal (MSM). It was determined that glucosinolate-containing extracts of MSM can be combined with active-enzyme-containing liquid extracts of meadowfoam seed to form a fermented product rich...

The influence of seed source origin and phenological characteristics on wood quality in a young Douglas-Fir Provenance Plantation

Creator:: Robinson, Walter P.
Abstract:: The relationships of several wood quality traits with seed origin and phenological characteristics, measured at a young age, were tested from six seed sources in a young Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) provenance plantation. The wood quality traits measured were wood density, uniformity of wood density, percentage latewood, fiber length,...

Habitat selection of hatchery and wild juvenile salmonids in Eagle Creek Basin, Oregon

Creator:: Brignon, William R.
Abstract:: To best manage Eagle Creek National Fish Hatchery and minimize any negative impacts that the current hatchery program may be having on Endangered Species Act-listed salmonids in the Eagle Creek Basin, I determined if wild fish are being displaced from preferred habitats by hatchery salmonids Oncorhynchus spp. This thesis had...

Chemically induced male sterility and natural out-crossing in selected wheat cultivars (Triticum aestivum L. em Thell)

Creator:: Ekse, Ali Osman
Abstract:: Three chemicals SD 55446, SD 55447 and WL 84245 were found to induce male sterility in cultivars of wheat or triticale. Both SD 55446 and SD 55447 when applied at a concentration of 0.896 kg/ha resulted in 90% male sterility. However, SD 55447 caused female sterility at the same concentration...
