Abstract

Currently, drought due to reduced precipitation as the most prevalent environmental stress in most climate zones, has affected the growth, development and yield of rain-fed crops. Today, the use of salicylic acid as one of plant growth regulator substances is a common way to increase plant resistance to stresses such as drought. This experiment was conducted in 2015 in order to determine the effects of different concentration and different application number of salicylic acid on increasing drought tolerance of fig cv. "Sabz" under rain-fed condition in Estahban region. Investigation was performed as factorial based on a randomized complete block design (CRBD) with three replications. The studied factors included salicylic acid in four levels (0, 0. 5, 1 and 1. 5 mM) and different number of foliar sparying in three levels (one, two and three times in three week intervals). The first foliar application of salicylic acid was carried out three weeks after caprification of trees. The measured parametersincluded chlorophyll, carotenoids, proline, Ion leakage, average leaf area, shoot growth, relative water content (RWC) and yield. The results showed that the use of salicylic acid increased chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, relative water content, proline and yield, but, decreased Ion leakage of the cell. Application of this compound did not significantly affect on shoot growth and leaf area. The effect of application number of salicylic acid on chlorophyll a, total chlorophyll and Ion leakage was significant, but, it had no significant effect on other traits. According to the results, the improvement of some physiological characteristics related to drought stress by salicylic acid has caused an increased in drought tolerance and in yield of fig under the rain-fed conditions.
