Abstract

This study was conducted with the main purpose to investigate the effect of super absorbent polymer and different levels of irrigation on characteristics of Myrobalan (Prunus cerasifera) seedling. The experiment was laid out in randomized complete design with five level (0.0, 0.5, 1, 2 and 3%) super absorbent polymer and three levels of water irrigation including 4 day (control), 8 and 12 day from germination until two month and each of these levels was repeated ten replication at Khorasan Razavi Natural Resources and Agricultural Research Center. During the experiment, the plants different physicomorpholigic such as plant height, number and surface of the leaf, fresh and dry weight of plant, number of root, root height and diameter of plant were estimated. The results indicated that the effect of interaction between super absorbent and water stress was significant on some of quantity characteristics of P. cerasifera. In all traits, a significant decrease was observed with increase in stress level. The highest plant height, number and surface area of the leaf, fresh and dry weight and diameter of plant was related to irrigation after 4 days with 3% polymer application and the lowest was related to irrigation after 12 days with no application of polymer. The results indicated that using S.A.P controlled of relationship soil, water and plant, decrease water stress.

Key words: Level irrigation, Prunus cerasifera, superabsorbent polymer, water stress.
