Abstract

The importance of studying the effects of environmental stresses, especially drought stress and their role in predicting and evaluating the growth and yield of crops is very clear. Therefore, in order to investigate the effect of water stress on proline content of two chickpea cultivars, a greenhouse experiment was carried out in a factorial arrangement in a completely randomized design with two factors and three replications (each replicate including two pots). Experimental treatments consisted of two different chickpea cultivars including arman and hashem cultivars and two levels of irrigation (optimal irrigation and low irrigation at 50% crop capacity). The soil moisture content was controlled daily by tensiometer. The results showed that proline increased under water deficit condition. Also, water deficit stress was observed decreasing in plant height and number of pods per plant, so that arman and hashem cultivars showed a decrease of 23.59% and 82.88% respectively at plant height. According to the results, it can be said that in FC 50% was more tolerant than hashem cultivar.
