The trial was conducted in the Po Valley (Northern Italy, 44deg.N, 33 m a.s.l.), for three years on a field which consisted of a plane on a 1.6% slope with respect to the underlaying horizontal water table, in order to determine the water status of peach. Treatments in comparison were: two rootstocks and two hydrological regimes. Measurements of stomatal conductivity by diffusion porometer and leaf temperature by infrared thermometer were performed during the irrigation season. The water table did not affect stomatal conductance in relation to both irrigation and rootstock, with higher value for the irrigated treatments. Stomatal conductivity data showed that all treatments exhibited lower values in presence of shallow water table, due to a 35-40 cm of capillary fringe. Infrared temperature was always lower than air temperature, increasing with deepening of groundwatertable level
