Wine aroma is one of the most important aspects of wine quality and yeast contribute a significant amount of the volatile aroma compounds in wine. However, our understanding of the contribution of specific yeast to Pinot noir aroma is still limited. In particular, the contribution of non-Saccharomyces yeast species present...
Competition between ‘Pinot noir’ grapevines and alleyway cover crops
was evaluated in two commercial vineyards in western Oregon. Seven
cover crop treatments including a clean-cultivated control were applied
in the fall of 2003 and their impact on vines was monitored in 2004
and 2005. Competition with grapevines was assessed by...
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...
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:
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...
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...
