Imaging fluorescent determination of energetics of chloroplast division and related matters

Creator:: Zheng, Ping
Abstract:: During exploration of imaging photosynthetic fluorimetry of Arabidopsis thaliana mutants, we discovered a novel phenomenon wherein photosynthetic efficiency (defined in Ning et al., 1995) is shown to plot in discrete groups. This exploration resulted first in the development of a spectrofluorometric method that apparently allows for in vivo observation of...

Non-specific innate immunity against Escherichia coli infection in white leghorn chickens

Creator:: Huang, Hsuan-Jen
Abstract:: This research was initiated to investigate a high mortality problem occurring in market age broiler chickens in Oregon. Initial field investigations revealed that mortality was due to the systemic bacterial infections. The subsequent laboratory experiments suggested that suppressed short-term, non-specific innate immunity rather than pathogenic properties of bacteria caused the...

Evaluating Field Production Issues by Investigating Grain Dormancy and Plant Segregation Patterns in Soft White Winter Wheat

Creator:: McCarthy, Christy A.
Abstract:: Wheat (Triticum aestivum) is a highly valuable crop that makes up a large portion of the world’s food. However, breeding for improved varieties with desirable characteristics can be a challenge. This research examined two different issues wheat breeders deal with throughout the selection process all the way to production of...

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...

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...

Improving in vitro mineral nutrition for diverse red raspberry and Rubus germplasm

Creator:: Poothong, Sukalya
Abstract:: Red raspberry, Rubus idaeus L., is a valuable crop for the U.S. Pacific Northwest and clonal propagation is required to produce disease-free plants and for germplasm preservation. One challenge of red raspberry micropropagation is the wide variation in growth response among the cultivars. The studies described in this dissertation were...

Ecosystem Processes in Treated and Untreated Western Juniper Systems in Semiarid Watersheds: A Paired Watershed Study in Central Oregon

Creator:: Abdallah, Mohamed AB.
Abstract:: Western juniper (Juniperus occidentalis) encroachment has been associated with negative ecological and hydrological consequences including reductions in herbaceous production and diversity, deterioration for wildlife habitat, and higher erosion and runoff potentials. As a result, western juniper removal is a common and accepted rangeland management practice. Although studies evaluating the ecological...

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...

Differential Effects of First Year Wheat Genotype on the Suppression of Take-All Disease and the Establishment of Suppressive Microbial Agents in the Rhizosphere

Creator:: Perkins, Evan M.
Abstract:: Recent research in the UK has found that the wheat cultivar grown in the first year can have a significant impact on the amount of take-all that develops in the second year, regardless of the cultivar planted in year two. ‘Einstein’ is one such cultivar that reduces take-all disease (reduced...

Paired watershed ecological analysis

Creator:: Fisher, Michael, (Michael Patrick), 1966-
Abstract:: This study was designed to provide a physical and ecological analysis of paired watersheds in the semi-arid western juniper (Juniperus occidentalis) woodlands of Central Oregon. Instrumentation and monitoring was accomplished in Jensen and Mays watersheds as the preliminary portion of a longer term project. Instrumentation was designed to address changes...
