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...

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...

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:: Jordan, David
Abstract:: Pedicel necrosis is a grape disorder that is recorded in all the world's grape growing regions. Synonyms for similar disorders include stiellahme (Germany, Switzerland), dessechement de la rafle (France), palo negro (Chile), shanking (New Zealand, Britain) and waterberry (USA). Pedicel necrosis can be a serious problem. Large reductions in yield...

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...

Creator:: Silva, Elisabete, Sampaio, Tiago, and Candolfi-Vasconcelos, M. Carmo
Abstract:: This study integrates various vineyard practices that may improve nitrogen availability to the vine, particularly during ripening . Different strategies aimed at improving fermentation behavior and wine quality are being evaluated. This study aims to optimize fruit quality and maximize the juice nitrogen fraction that can be used by yeast...
