Pomegranate is a crop tolerant to water deficit and is suitable in areas of water scarcity. This work presents results from a three year study on different levels of water deficit applied at the beginning,end or during the growth period of the pomegranate cv. Wonderful fruit under full production and young plants raised in 1 m3 containers. Over this period the following parameters were measured: gas exchange, chlorophyll fluorescence, soil and xylem water potential, solar radiation intercept, osmotic adjustment and fruit and shoot growth. Fruit weight, yield and size were determined at harvest. The results help determining controlled water stress thresholds and periods for the production of fresh fruit.
