The effects of irrigation regime (0.3, 0.5 or 0.7 bar) on stomatal frequency in grape rootstocks (Dogridge, Salt Creek, 1613-C, 1616-C, 1103-P and SO4) were studied in Rahuri, Maharashtra, India, during 2000-01. Rootstocks grown under an irrigation regime of 0.3 bar (field capacity) had greater stomatal frequency (167.91/mm2) than those grown under an irrigation regime of 0.7 bar (124.92/mm2). The stomatal frequency in leaves decreased with the increase in water stress. The effect of the interaction between rootstock and irrigation regime on stomatal frequency was significant. Stomatal frequency was greatest in SO4 under irrigation regimes of 0.3 (218.56/mm2) and 0.5 bar (211.25/mm2), and lowest in 1103-P under an irrigation regime of 0.3 bar (108.06/mm2). Based on the reduction in stomatal frequency/mm2, 1103-P was the most drought tolerant, followed by Dogridge, Salt Creek, 1613C, 1616C and SO4.
