Abstract

Growth chamber estimation under severe water-stress of behaviour of 4 cherry rootstocks (seedling, Colt, CAB/6 P and CAB/11 E) was carried out through the measure of leaf water potential, stomatal conductance and transpiration rates. This experience showed a positive correlation between leaf water potenti al and stomatal conductance, a difference equivalent to 1,0 - 1,5 M Pa, O,5 - O,7 . sec→1and 15/h/m2of water respectively in leaf water potential, stomatal conductance and transpiration rates between irrigated and stressed trees. In particular, CAB/6 P selection resulted the most sensible to water stress, followed by CAB/11 E, Colt and seedling; the last one kept more intense transpiration rates and showed more rapid restarting of stomatal conductance during recovery than Colt.
