Research Project: IMPROVING FRUIT AND FRUIT PRODUCTS QUALITY IN THE PACIFIC NORTHWEST

Location: Horticultural Crops Research

2011 Annual Report


1a.Objectives (from AD-416)
Identify and evaluate vineyard practices within the Pacific Northwest that produce high quality fruit and fruit products.


1b.Approach (from AD-416)
Both parties will examine vine characteristics and major chemical components responsible for any differences, or similarities, between differing vineyard practices. We will use simple spectrophotometric methods in addition to more complex analytical methods (HPLC), to better understand qualitative and quantitative effects on grape phytonutrients. Formerly 5358-21000-034-33S (12/2008).


3.Progress Report

This research relates to objective 3 of the parent project. Research progress was made to better understand the function of plant hormones (i.e. abscisic acid) involved in dealing with water stress during the critical berry ripening period. Different hormone sprays were applied to the experimental vines to evaluate berry shrivel prevention, and fruit maturity indexes have been collected.

Methods of project monitoring included meetings, e-mail, and phone calls.
