Project Number: 5358-21000-041-06
Project Type: Grant

Start Date: Sep 24, 2007
End Date: Sep 30, 2009

Objective:
1. Understand the dynamics of water flow in the current season shoot of vines of a given vigor by examining the anatomical features of the xylem along the shoot length at different intervals (bottom, middle, and top of the shoot). This will provide insights into how the spatial differences in xylem anatomy are related to water movement in a growing shoot during the current season. 2. Examine xylem anatomy of trunks, cordons, and current season shoots with different vigor levels.

Approach:
Plant material to carry out the anatomical work for this proposal will be obtained from field-grown grapevines (Vitis vinifera L. cv. Merlot). The purpose of measuring xylem anatomical features is to understand whether there is a functional relationship between xylem vessel anatomy and vine vigor.
