Evaluation of drought stress effects on morphological, physiological and agronomical charactristice of Kabuli chickpea genotypes in greenhouse

In order to evaluate the effect of drought stress on morphological, physiological and agronomical charactristice of tolerant, semi tolerante and sensitive Kabuli chickpea genotypes, a greenhouse exprimemt was conducted in factorial based on completely randomized design with three replication. The first factors included of no water deficit stress, mild stress and sever stress and second factor included of 11 genotypes. Analysis of variances results indicated significant effect of genotype factor between all the traits exept relative water content and all intractions of genotype * irrigation were significant except root dry weight, shoot dry weight, root diameter, shoot length and primary branch numbers. The greatest percentage of trait changes belonged to shoot dry weight, shoot fresh weight and biological yields in high drought stress and the lowest percentage of trait changes belonged to rate of water lost. The tolerant genotype of Fars shahpoor-3659 with low canopy temperature had the highest root fresh weight, shoot fresh weight and shoot length under non stress conditions and the sensitive genotype of Fars shahpoor-3723 with high canopy temperature had low biomass yields, root fresh weight, shoot fresh weight and shoot dry weight which showed reduction of root diameter, primary branch numbers and relative water content under high stress, too. Thus, these two genptypes could be used as indexes for identification of tolerant and sensitive varirties in later experimets.
