A nonexperimental test of the contingent valuation method : comparing hypothetical and actual voting behavior

Creator:: Vossler, Christian A.
Abstract:: This study compares the results of a contingent valuation (CV) mail survey and the voting outcome of a bond measure to fund improvements, through property tax increases, to a downtown park and adjacent riverbank in Corvallis, Oregon. In addition to asking survey respondents about their voting decision, respondents are presented...

Ion exchange membranes and agronomic responses as tools for assessing nutrient availability

Creator:: Salisbury, Steven Earl
Abstract:: Winter wheat is commonly grown in rotation with leguminous and non-leguminous crops in the Willamette Valley. For agronomic, economic, and environmental reasons it is important to understand the influence of previous crops on availability of N and other nutrients. Objectives of this study were: (1) to evaluate the effects of...

Annual bluegrass (Poa annua L.) emergence under different residue management practices in perennial ryegrass and determination of resistant and susceptible annual bluegrass germination under controlled temperature and moisture

Creator:: Schuster, Matthew D.
Abstract:: With the loss of field burning the amount of crop residue that remains in perennial ryegrass fields has increased. As the amount of crop residue remaining in the field increases so does annual bluegrass. This has resulted in the increased use of herbicides to control annual bluegrass. However, this increased...

Small broomrape (Orobanche minor) biology and management in red clover (Trifolium pratense) seed production

Creator:: Lins, Ryan D.
Abstract:: Small broomrape (Orobanche minor) is a parasitic weed that attaches to the roots of red clover (Trifolium pratense). Small broomrape invasion presents a significant threat to the future of red clover seed production in Oregon. This study was conducted to investigate and develop small broomrape management options for red clover...

The acetohydroxyacid synthase gene family its role in herbicide resistant sunflowers

Creator:: Hawley, Robin M.
Abstract:: Resistance to acetohydroxyacid synthase (AHAS)-inhibiting herbicides has been reported in over 90 weedy species, including wild sunflower biotypes, since the herbicides were developed in 1982. The AHAS gene family in sunflower, consisting of three paralogs AHAS1 , AHAS2, and AHAS3, has been targeted for inducing herbicide resistance. A polymorphism identified...

Fallow water retention and wheat growth as affected by tillage method and surface soil compaction

Creator:: Schillinger, William F.
Abstract:: No-tillage winter wheat (Triticum aestivum L.) grown in a wheat-fallow cropping system has consistently produced lower grain yields than conventionally tilled soils in the semiarid Pacific Northwest. A 2-year study was conducted in a long-term tillage trial at Moro, OR to determine factors responsible for differences in wheat growth and...

Dissecting induction of cell cleavage

Creator:: Alsop, G. Bradley
Abstract:: Cytokinesis separates replicated chromosomes and cytoplasm into two daughter cells. In animal cells, this is achieved by the formation of a cleavage furrow that bisects the mitotic (or meiotic) spindle. It is known that the mitotic apparatus defines the cell cleavage plane. However, it is not clear how the mitotic...

Relationships between forest-floor invertebrate distribution, movement, and microclimate under alternative riparian management practices

Creator:: Rykken, Jessica J.
Abstract:: Headwater streams and their riparian zones are a common, yet poorly understood, component of Pacific Northwest landscapes. I sought to describe the ecological significance of headwater stream riparian zones as habitat for forest-floor invertebrate communities, and to assess how alternative management strategies for riparian zones may impact these communities. I...

Biological control of Tetranychus urticae (Koch) on peppermint by Neoseiulus fallacis (Garman) : density relationships, overwintering, habitat manipulation and pesticide effects

Creator:: Morris, Mark Alan, 1954-
Abstract:: Several aspects affecting population trends and overwintering of Neoseiulus fallacis (Garman) on peppermint were examined. Neoseiulus fallacis was the most abundant phytoseiid predator mite found in peppermint surveys throughout the western U.S. Results of pesticide exclusion and cage studies showed that N. fallacis controlled Tetranychus urticae (Koch) on peppermint in...

Ryegrass fluorescence expression during three generations of seed increase and its heritability among half-sib families

Creator:: Floyd, Donald J.
Abstract:: Seedling root fluorescence (SRF) has been used as a test in the USA since 1941 to discriminate Italian ryegrass (Lolium multiflorum Lam.) from perennial ryegrass (L. perenne L.). Generally, roots of Italian ryegrass fluorescece when exposed to ultraviolet light, while roots of perennial ryegrass do not. Presence of fluorescent seedlings...
