摘要：

Results of three field experiments where crop load and irrigation schedules effects were studied in Israel are reported. Crop load (yield/pruning weight) was found to be affected by irrigation due to a differential effect of irrigation on fruit bud differentiation and on vegetative growth. Irrigation schedules interaction with crop load resulted in lon fruit and wine quality in the low crop load a intensive irrigation combination in cv. Cabernet Sauvignon. A combination of moderate irrigation along the entire season with a crop load of 7 resulted in the best quality wines. Irrigation cut back after veraison was found to reduce fruit quality of Sauvignon blanc vines in the Golan Height region. Stem water potential was found to better represent water status of vines than leaf water potential.
