Effect of Plant Growth Regulator and Irrigation on Physiological and Harvest Maturity of Red Clover in Relation to Seed Quality

Creator:: Angsumalee, Duangporn
Abstract:: Red clover (Trifolium pratense L.) seed yield can be affected by plant growth regulators (PGR) and irrigation; however, the effects of these factors on physiological maturity (PM), harvest maturity (HM), and seed quality are unknown. The objectives of this study were to: 1) determine how irrigation and trinexapac-ethyl (TE, a...

Trinexapac-ethyl timing and rate effects on crimson clover (Trifolium incarnatum L.) seed yield and seed yield components

Creator:: Morad, Mohammed
Abstract:: Oregon is the world’s leading producer of crimson clover (Trifolium incarnatum L.) seed. Recent research has reported that seed yield has been increased in cool-season grass and red clover (T. pratense L.) seed crops with the application of trinexapac-ethyl, a gibberellic acid biosynthesis inhibiting plant growth regulator (PGR) and lodging-control...

Investigating the Current Teaching Evaluation Practices used in Engineering Programs and their Usefulness to Educators

Creator:: Villanueva, Keisha A.
Abstract:: Evaluation of teaching is used to examine and improve teaching quality in higher education. The literature consists of best teaching evaluation practices that have been developed, yet there is little research that has been conducted which investigates teaching evaluation practices in engineering programs. This thesis represents two manuscripts that explore...

Pre- and Post-settlement Processes of Northern Rock Sole (Lepidopsetta polyxystra) in Relation to Interannual Variability in Temperature and Productivity in the Gulf of Alaska

Creator:: Fedewa, Erin J.
Abstract:: Understanding the effects of climate variability on growth dynamics and timing of early life history events in marine fishes can provide insights into survival, recruitment and productivity. Field collections (2005, 2007, 2009-2011) were combined with otolith microstructural analysis to examine interannual variation in larval and juvenile growth rates, size at...

Expanding the Use of 19F NMR Spectroscopy in Per- and Polyfluoroalkyl Substance Analysis: Determination of Total Fluorine and Isomeric Distribution in Aqueous Film-Forming Foams

Creator:: Schaum, Andre F.
Abstract:: Aqueous film-forming foams (AFFFs) are significant sources of per- and polyfluoroalkyl substances (PFAS) in the environment. Current analytical methods that provide quantitative measures of individual PFAS in AFFFs, such as liquid chromatography – tandem mass spectrometry (LC-MS/MS), are often complicated, time-consuming, and expensive. Methods for total fluorine analysis, though quantitative,...

A biological and systematic study of the armored boreid, Caurinus dectes, with comparative notes on related mecoptera

Creator:: Russell, Loren Kenneth
Abstract:: Caurinus dectes Russell is a minute, brachypterous scorpionfly which was discovered at Marys Peak, Benton County, Oregon, in 1976, and subsequently described as the only representative of the subfamily Caurininae within the Boreidae (snow scorpionflies). Caurinus dectes is now known to range from the Olympic Peninsula and Northern Cascades in...

Distribution, Abundance, and Settlement of Slope-spawning Flatfish during Early Life Stages in the Eastern Bering Sea

Creator:: Sohn, Dongwha
Abstract:: Changes in environmental conditions in marine ecosystems could directly or indirectly influence distribution, abundance, settlement, and size at settlement of flatfish. Understanding species-specific and age-specific responses to environmental variability is important for managing commercially important flatfish stocks. Slope-spawning flatfish whose offspring rely on extensive drift from the slope (spawning) to...

The Responses of Slope-spawning Flatfish to Environmental Variability in the Eastern Bering Sea

Creator:: Vestfals, Cathleen D.
Abstract:: When adult spawning and juvenile settling locations of marine fishes are geographically separated, their early life history stages must rely on transport and their own behavior to move them toward suitable habitats for successful recruitment to the juvenile phase. Variations in climate may reduce the availability of spawning and juvenile...

Continuous monitoring and modeling to assess pesticide exposure in critical habitat for Pacific salmonids

Creator:: Janney, Philip K.
Abstract:: Pacific Northwest and California freshwater resources are key elements in the life history and ecology of Pacific salmon and steelhead listed as threatened or endangered under the Endangered Species Act. Risk to listed Pacific salmonid species can be assessed by evaluating the spatial and temporal co-occurrence of salmonid species at...
