Title: Using Rootstocks to Manipulate Vine Physiological Performance and Mediate

摘要: A rootstock trial was established in 1997 at the OSU Woodhall vineyard, located Southern Willamette Valley, which included two experiments. The first experiment a factorial of four varieties grafted on to 9 rootstocks, and also as ungrafted vines (a splitplot design). second randomized complete block design Pinot noir 19 vines. Evaluation these experiments conducted order assess impact vine physiological performance, fruit wine composition, between 2002 2005. While there were changes gas-exchange hydraulic properties scion response different not directly linked size. Some rootstocks could cope with large water demand that their larger canopies required, while other appeared have reduced canopy size strategy drought avoidance. Evidence indicated Vitis can induce stomatal behavior under conditions.
