Grape Powdery Mildew Management: The Interaction Between Inflorescence Stage and Fungicide Chemistry

Creator:: Warneke, Brent W.
Abstract:: Grape powdery mildew (GPM, causal agent Erysiphe necator) is the most economically important disease of grapevine in the Western U.S. Low levels of GPM infection on clusters (1-5%) can negatively affect wine sensory quality, so intensive fungicide programs are common. This may lead to problems like excessive fungicide use and...

Environmental Factors Affecting Phytophthora Root Rot of Rhododendron

Creator:: Mestas, Angie
Abstract:: Phytophthora root rot decreases availability and quality of rhododendrons produced in the USA. Symptoms of Phytophthora root rot include root necrosis, leaf chlorosis, stunting, and permanent wilt. The purpose of this thesis was to better understand the impact of root damage, soil moisture, nitrogen fertilizer application, and pathogen species on...

Early testing of Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) for Swiss needle cast tolerance

Creator:: Temel, Fatih
Abstract:: The relationship between the level of Phaeocryptopus gaeumannii (Rohde) Petrak colonization and severity of Swiss needle cast (SNC) symptoms, the possibility of early testing of Douglas-fir (Pseudotsuga menziesii var. menziesii [Mirb.] Franco) for SNC tolerance, and geographic variation in coastal Oregon with respect to SNC tolerance were investigated. Comparisons between...

Effect of Regulated Deficit Irrigation on Malbec and Syrah Grape and Wine Quality

Creator:: Yuan, Xiaoxi
Abstract:: The water status of grape vine throughout the growing season is a primary determinant of vine vigor and berry composition. The concentrations of volatile compounds and precursors in grape berries are highly influenced by viticultural practices. Imposing a water deficit on the vine during berry development is an important vineyard...

Localization and genetic mapping of some factors influencing rachis brittleness and free-threshing habit in wheat

Creator:: Nalam, Vamsi J.
Abstract:: Domesticated forms of wheat exhibit traits that have increased their adaptation to cultivation by humans. Some of the most critical adaptive differences involve changes to morphological features that make the crop easier to harvest like ear rachis stiffness (brittle to non-brittle rachis) and the ease with which the seed is...

Seed protein and chromosome number analyses of experimental wheat x jointed goatgrass (Aegilops cylindrica Host) hybrid derivatives

Creator:: Crémieux, Lis︡ele
Abstract:: The occurrence of seed-producing wheat x jointed goatgrass hybrids in infested wheat fields suggests the possibility of gene flow between the two species. This study investigates 'Madsen' wheat x jointed goatgrass F₁ and reciprocal backcross derivatives produced in experimental field plantings. Electrophoresis of the high molecular weight (HMW) glutenin seed...
