The effect of various physio-biochemical parameters on the water use efficiency (WUE) of grape varieties, rootstocks and budded vines was studied in 3 separate experiments at 3 levels of irrigation (100%, 50% and no irrigation) for 14 days of stress cycle. None of the varieties or rootstocks could survive beyond 4 days under the no irrigation treatment. Considerable genetic variability was observed for WUE with respect to photosynthetic rate, transpiration rate, stomatal conductance, root to shoot length ratio, abscisic acid, zeatin riboside, carbon isotope discrimination etc. among grape rootstocks, viz., Dogridge, 1613 C, Salt Creek, St. George and Vitis champinii …
