Research Project:
ROOTSTOCK AND SCION INFLUENCES ON GRAPE AND WINE COMPOSITION AND QUALITY
Location: Horticultural Crops Research
Project Number: 5358-21000-034-20
Project Type:
Grant
Start Date: Sep 11, 2006
End Date: Sep 30, 2009
Objective:
1) Evaluate whether rootstocks alter winegrape fruit composition during
ripening and at harvest compared with winegrapes grown on their own roots.
2) Test for interactions between winegrape variety (scion) and rootstock
in terms of fruit composition.
Approach:
Conduct a field experiment with three winegrape varieties (Merlot,
Syrah, Chardonnay) that are either grown on their own roots or grafted
to six different rootstocks. Fruit samples will be collected weekly from
veraison through harvest from each variety/rootstock combination,
weighed and analyzed for soluble solids, pH, titratable acidity, and
color using standard laboratory practices. Documents Grant with Washington State University.
