Pomegranate (Punica granatum) is a subtropical tree that is cultivated in many regions of the Iran. Change in climatic conditions and the has prevailed in most of the pomegranate growing areas caused tension in the pomegranate orchards and has affected the growth and fruiting. to evaluate the responses of Rabbab pomegranate tree to different irrigation regimes, the present study was carried out during 2019 and 2020 in Koh-Chenar city in Fars province. The experiment was conducted in the form of a RCBD with three replications. Five irrigation treatments included, control and irrigation when the soil reached 35, 50, 65 and 80% soil moisture discharge. The results showed that reducing the amount of irrigation caused a decrease in yield in all low irrigation treatments and a significant decrease in fruit weight and aril dry weight in 65 and 80% moisture depletion . The highest amount of proline was observed in 80% moisture discharge at the rate of 0.476 (µmol/ leaves fresh weight)The highest activity of catalase and sodenzymes were observed in 50% moisture depletion. According to the changes in average fruit weight, aril weight and percentage of aril paleness, it can be concluded that the pomegranate tree of the Rabbab has tolerated well up to 50% moisture depletion and the fruit has maintained its quality, but the depletion higher soil humidity (65 and 80%) caused a decrease in the quantitative and qualitative characteristics of the fruit and yield, and the aril paleness of the fruit increased
