Recent research shows that flower parts of strawberry (Fragaria X ananassa Duch.) differ in their capacity to support the growth of Botrytis cinerea, the fungus which causes gray mold on fruit. Growth in styles is slow and hyphae rarely enter the carpel (achene), suggesting that this pathway is not the...
Many parts of the West are experiencing substantial growth pressures that have increased the demand for water. These new demands come at a time when most of the water in the West has been fully appropriated by traditional uses such as agriculture, mining, and industry. Some attempts are being made...
This thesis examines forest history of a portion of the Douglas-fir Region: Soap Creek Valley, a 15,000 acre sub-basin of the Luckiamute River in northern Benton County, Oregon. The primary reasons for the research were to test oral history methodology, document sub-basin scale forest cover pattern changes, and determine basic...
This study was conducted to determine the effects of
shipping stress on the immune system in domestic lambs (Ovis
aries) and to determine the potential of the thymic peptide,
thymulin, to reduce those effects of stress on the immune
system. Treatments consisted of no shipping (as unstressed
controls), shipping (as...
The level of polymorphisms of many biochemical and DNA markers are low in
cultivated sunflower (Helianthus annuus L.). The number of mapped public DNA
markers is limited. Molecular markers have not been developed for the most
important diseases of sunflower, such as downy mildew. The objectives of this
study were...
The performance of the meat products industry, the largest food processing sector in the U.S. in terms of shipment value, is an important issue. A key indicator of its performance is productivity growth, which results in reduction in the cost of production at given input prices. The present study employs...
Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in
Oregon around 1957 before newly developed technology and fiber cultivars were
available. The purpose of this research was to explore the use of modern methods and
new cultivars.
Field studies were conducted to evaluate cultivars and optimum cultural...
A qualitative research approach composed of three strategies was employed to systematically examine the politics of natural resource collaboration. First, using the Oregon Plan for Salmon and Watersheds as a case study, the behavioral assumptions of natural resource policy instruments enabling collaboration were uncovered and analyzed. Three key assumptions emerge:...
