Abstract

 Mature peach trees [Prunus Persica (L.) Batsch] grown in weighing lysimeters were subjected to soil moisture stress by shutting off irrigation. Initially transpiration (T) was at potential rate when available soil moisture in the active root zone was near field capacity. Rapid changes in soil moisture under drying cycles caused gradual decrease in transpirational rate. When 0 to 60 cm soil layer reached permanent wilting point, there was a sharp decline in water use. Mature peach trees require barest minimum of 10  mm of water for their metabolic activity. A regression model has been developed to estimate transpirational loss of peach from available soil profile water.
