    The experiment was conducted in 2015 and 2016 in the Agricultural Experimental Station in Lipnik (53°20′35″N 14°58′10″E), Poland. The main goal of the study was to assess the characteristic features associated with water use efficiency and index of leaf greening of fruit trees. The experiment was designed by the randomized block method in 7 replications (one tree – one replicate) for cherry cv. ’Łutówka’, 5 replications for sweet cherry cv. ‘Vanda’, 7 replications for apple cv. ‘Rubinola’ and 4 replication for plum cv. ‘Amers’. The experimental factor was under-crown watering: 0 – control objects with no irrigation, W – irrigated objects, at the level of moisture –0.01 MPa of the water potential. Irrigated cherry and sweet cherry trees were characterized by significantly lower assimilation and transpiration intensity as well as stomatal conductance. In apple and plum cultivation, irrigation remarkably enhanced the assimilation and transpiration intensity. All tested fruit tree species grown on irrigated objects were distinguished by higher value of water use efficiency (WUE) and momentary water use efficiency (WUEI). Index of leaf greening was significantly lower for irrigated trees.
