Creator:: Taylor, Patrick and Candolfi-Vasconcelos, M. Carmo
Abstract:: A broad range of factors influence wine grape quality and manipulation of these factors has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends...

Creator:: Creasy, Glen L. and Breen, Patrick J.
Abstract:: The connection between the fruit-set disorder Inflorescence Necrosis (IN) and high ammonium (NI14+) in affected tissues has led to an investigation of NH4+ assimilation enzymes (principally glutamine synthetase (GS) and glutamate synthase) in grape tissues. Previous work in this department has suggested that toxic levels of NH4+ build up in...

Creator:: Creasy, Glen L. and Breen, Patrick J.
Abstract:: Inflorescence Necrosis (IN) has been an unpredictable problem for grape growers in Oregon. The industry has seen significant losses due to this fruit set disorder in several out of the eight years since its first description in 1988, particularly in Pinot noir. Little is known of how to prevent the...

Creator:: Ratliff-Peacock, Joey, Candolfi-Vasconcelos, M. Carmo, and Henry, Scott
Abstract:: For this trial, established Pinot noir vines, located on the valley floor of the Umpqua Valley in Oregon were used. In 1996 and 1997 sixteen vines trained to the Scott Henry trellising system were separated into four different quadrants, determined by shoot orientation: Bottom canopy, shoots trained toward the ground;...

Creator:: Miller, Marilyn L., Pinkerton, Jack, and Moore, Larry W.
Abstract:: Grafted grapevines will become increasingly important in Oregon vineyards in order to prevent loss of plants to phylloxera infestations. Several rootstocks are now being evaluated in Oregon for horticultural traits and characteristics related to wine quality. Resistance or tolerance to other plant diseases affecting grapevines needs to be examined as...

Creator:: Moore, Larry W. and Canfield, Marilyn
Abstract:: The objectives of this study are to isolate and characterize pathogenic agrobacteria that cause crown gall in grapevines and test hot water dips as a method for eradicating the infectious bacteria . Crown gall is commonly found among Oregon vineyards and the causative agent, Agrobacterium vitis, is known to be...

Creator:: Briggs, Cynthia A. (Cynthia Ann)
Abstract:: Research mentorship is a new construct emerging in the literature, but remains inadequately defined and scarcely researched. This topic is of relevance to counselor education because of the paucity of literature on the topic, and because of our professional commitments to diversity, wellness, and scholarship. Effective mentorship has been shown...

Creator:: Schreiner, R. Paul, Pinkerton, John N., and Bryla, David
Abstract:: Objectives: To evaluate the impact of the ring nematode, Mesocriconema xenoplax on the physiology and productivity of phylloxera-resistant grape rootstocks as a basis for recommending rootstocks in the Pacific Northwest. Specific objectives for 2006: Spring: Inoculate soil with AMF and M. xenoplax. Plant vines. Growing season: Monitor plant growth, gas...

Creator:: Schreiner, R. Paul
Abstract:: Objectives of Proposed Research: The goals of this project for the next few years are: 1) to develop optimal tissue nutrient levels for N, P, and K in winegrapes that are based on physiological performance and fruit quality, 2) to identify the best tissue (leaf vs. petiole) and time of...
