Research Project:
IDENTIFY DROUGHT RESISTANT GRAPEVINE CULTIVARS FOR SUSTAINING GRAPE PRODUCTION IN DROUGHT CONDITIONS
Location: Horticultural Crops Research
Project Number: 5358-21000-034-32
Project Type:
Grant
Start Date: Aug 19, 2008
End Date: Sep 30, 2009
Objective:
1. Investigate leaf anatomy and morphology of well-watered and water-stressed grapevines using light and electron microscopy.
2. Monitor berry ripening and fruit quality characteristics of well watered and water stressed grapevines.
Approach:
Research will be conducted on two cultivars in a greenhouse and drought conditions will be simulated. Leaves will be tagged on the vines of both cultivars to determine leaf age. During the dry-down and re-watering cycles, the physiological, anatomical, and morphological characteristics will be measured in both cultivars to assess drought resistance. Prior to sampling tissues for all microscopy studies, photosynthesis, dark respiration, and stomatal conductance will be measured on leaves of well-watered and water-stressed grapevines. Fruit quality characteristics such as Brix, pH, titratable acidity, color etc., will be measured to examine ripening behavior and quality characteristics during dry-down and re-watering cycles.
