A broad range of factors influences wine grape quality and its manipulation 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 largely on...
Vineyard acreage in Oregon continues to increase at a rapid pace. In the past two years alone 1600 acres of new vineyard land have been planted (Rowley et al., 2000). Much of this has been on phylloxera-resistant rootstocks. This practice is strongly encouraged, since it is the only practical way...
Objectives of proposed research:
1. Investigate the relationship between abscisic acid (ABA) and auxins and the regulation of carbon partitioning.
2. Investigate the origin of ABA present in the fruit during ripening and attempt to modify the partitioning pattern through manipulation of endogenous ABA levels using mefluidide (ABA biosynthesis promoter)...
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...
