Stomatal conductances (Cs) and transpiration rates (Tr) decreased in response to both wind treatments. These responses disappeared within one day for all cultivars when the 3.6 ± 2.5 m sec-1 wind was stopped; however, the effects on Cs and Tr continued for longer periods for some cultivars when the 10.7 ± 3.0 m sec-1 wind stopped. Leaf water potentials were not affected by either wind treatment. When vines were preconditioned with 0.9 to 1.3 m sec-1 winds prior to the 3.6 m sec-1 wind treatment, no differences in Cs and Tr were observed compared to vines not receiving prior wind conditioning.
