Location: Horticultural Crops Research2011 Annual Report
1a. Objectives (from AD-416)
The objective of this cooperative research project is to determine the balance between canopy and crop level manipulation in vineyards, and to quantitatively assess the effects of so-called 'vine balance' on fruit chemistry.
1b. Approach (from AD-416)
A field-based approach will be taken, using mature wine grape vineyards. Crop load will be adjusted to within, above- and below- the wine industry's standard recommendations for the cultivar and production district. All other vineyard management will follow standard practices for the cultivar and production district. Canopy and fruit microclimates will be characterized quantitatively at physiologically important stages of vine and grape berry development. At commercial maturity, fruit will be analyzed for standard maturity indices, phenolics, and other compounds associated with quality.
3. Progress Report
This research relates to objective 2 of the parent project. The project goal is to identify and evaluate vineyard practices within the Pacific Northwest that produce high quality fruit and fruit products. Recruitment has recently been completed for support staff needed on this project and vines for the experiment have been identified. Methods of project monitoring included meetings, e-mail, and phone calls.
