In this study, drought resistance ability of Myrobolan B, Myrobolan GF-31, Marianna 8-1 and Pixy plum clonal rootstocks were investigated. Moreover, some physiological changes of these rootstocks in different watering regimes were observed. The potted plants in the greenhouse were watered 100%, 50% and 25% of available soil water, when the outside temperature was the highest for plants. In all rootstocks a linear correlation was obtained between the amount of water given to the plants with leaf water potential and relative water content. During growth and development, fading of leaving due to senescence was further enhanged by limited watering regime. The drought resistance durations were the longest Pixy and Marianna 8-1
