Variability in fruit set and yield is a serious problem in Oregon viticulture, particularly with Pinot noir. Climatic variation during the flowering period contributes significantly to this problem by affecting fruit set and cluster weight. Cool wet weather during bloom results in poor set, small clusters, and low yields. Seasons...
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...
The objectives of this study are to determine:
· How vine vigor and fruit composition vary in different alleyway management regimes: solid vegetative cover vs. every other alleyway of vegetative cover removed
· What differences are observed in different alleyway management regimes within a vineyard
· What differences are observed...
Objectives:
· Evaluate canopy management options available to Oregon growers for their effects on yield, grape composition, and wine quality.
· Investigate the relationships between vine growth, cluster environment, grape composition and wine quality.
· Develop techniques that improve the capabilities of Oregon winegrape growers to obtain consistent yields with...
The new varietal trial at SOES was monitored during the growing season and during ripening by David Sugar and Porter Lombard (see Winegrape Variety Trial in Southern Oregon). The 1993 vintage was a late ripening season and not all the varieties developed sufficient maturity for experimental wine production. Tempranillo, Viognier,...
Increased attention is being given to the promise of co-management as a means of achieving sustainable
fish stocks while at the same time providing benefits to those dependent on the fishery. At the same time,
the view that co-management represents a continuum between state or user control is being replaced...
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...
Different fermentation practices are generally believed to affect wine composition and wine quality of Pinot noir. Oregon winemakers, for example, commonly attribute differences in color and phenolic extraction to differences in processing. There is, however, little information from replicated trials with controls demonstrating the cause and affect of these perceived...
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...
