Effects of Biochar-Based Seed Coatings on Seed Germination and Seedling Vigor of California Brome (Bromus carinatus L.) and Blue Wildrye (Elymus glaucus L.)

Creator:: James, Matthew Scott
Abstract:: California brome and blue wildrye are important native grass species in the Pacific Northwest. However, both species have been reported to have low emergence under less than favorable field conditions. Seed coating is used to improve emergence and stand establishment of various crops. Three studies were carried out to determine...

Response of Roughstalk Bluegrass (Poa trivialis L.) to Waterlogging Stress

Creator:: Liu, Mingyang
Abstract:: Roughstalk bluegrass (Poa trivialis L.) (RB) is a weed species that increased very quickly in grass seed production fields of the Willamette Valley. The invasion of RB in grass seed crops often occurs in waterlogged soils. In waterlogged areas, RB exhibited better competitiveness and had greater population densities than other...

Improving Best Management Practices for Potato Production in the Columbia Basin : An Evaluation of Essential Oils for Control of Verticillium Wilt and the Fate of Chloride in the System

Creator:: Light, Sarah Elizabeth
Abstract:: Although the potato (Solanum tuberosum L.) is a global crop, few growing regions rival the high yields of the Columbia Basin of Eastern Oregon and Washington. Two research projects were conducted in Hermiston, OR to contribute to best management practices for the region. The first project evaluated the efficacy of...

Restoration of Annual Grass-invaded Landscapes in the Sagebrush Steppe using Perennial Grass Seed Technologies and Wyoming Big Sagebrush Transplanting

Creator:: Holfus, Corinna M.
Abstract:: Within the sagebrush steppe ecosystem, invasive annual grasses are of growing management concern as they outcompete native vegetation, change the fundamental nutrient cycling processes, decrease biodiversity, and increase frequency of wildfires. The most widely used and effective management tool to decrease invasive annual grass abundance, is the use of pre-emergent...

Seed quality and plant establishment studies of seashore paspalum (Paspalum vaginatum Sw.)

Creator:: Baker, Stanley D.
Abstract:: Seashore paspalum (Paspalum vaginatum Sw.) is an important warm-season perennial turfgrass, known for its tolerance to salinity. Turfgrass is used for homes, municipalities, sod farms, resorts, and sports fields. Seashore paspalum has historically been planted in sub-tropical and tropical climates because of its heat tolerance. Seashore paspalum could become an...

A Linear Mixed Model Framework for Spatio-Temporal Random Processes using the Separable and Product-Sum Covariance Structures

Creator:: Dumelle, Michael J.
Abstract:: We describe spatio-temporal random processes using linear mixed models and discuss estimation, inference, and prediction under this formulation. We show how many commonly used covariances are special cases of this more general framework and pay special attention to the separable and product-sum covariances. The linear mixed model formulation facilitates straightforward...

Predicting Help-Seeking Attitudes and Intentions and Life Satisfaction of First-Generation South Asian Americans Based on Acculturation Levels, Select Demographics, and Forms of Racial Stereotyping

Creator:: Michaels, Krupali S.
Abstract:: The literature on first-generation South Asian American (SAA) mental health is limited despite the increased focus of studies on help-seeking behaviors and subjective well-being over the past decade. Therefore, we designed a web-based survey seeking to address two research questions. Research Question 1 informed Study 1 of this dissertation project:...

Activated carbon incorporated into herbicide protection pods as a seed amendment technology for revegetation

Creator:: Clenet, Danielle R.
Abstract:: Reestablishing native perennial vegetation in annual grass-invaded rangelands is critical to restoring ecosystems, especially following wildfires. Controlling invasive annual grasses is essential to increasing revegetation success; however, pre-emergent herbicides used to control annual grasses prohibit immediate seeding due to non-target herbicide damage. Thus, seeding is often delayed one year following...
