Abstract

To study the effects of SALINITY on physiological and morphological traits of CHICKPEA two experiments were conducted in 2010 at Faculty of Agriculture and Natural Resources, University of Tehran. Seven CHICKPEA genotypes and 5 levels of SALINITY stress (Ctrl, 200, 150, 100, 50 mM) were used. Two laboratory and greenhouse experiments were conducted using RCBD design with 3 replications. Some traits were recorded such as germination percentage, root length, shoot length, and vigor index in laboratory. According to the results, mentioned traits had linear response with increasing of SALINITY stress. The highest and the lowest of germination percentage were obtained in 200 mM treatment for G485 and G456, respectively. G485 had the highest vigor index in response to 200 mM treatment. The biomass of pea genotypes was significantly affected by SALINITY levels, so the stress level of 50 mM in G485 with 3.8 g had the highest levels of biomass. In the second study, activities of catalase, peroxidase, polyphenol oxidase, total CHLOROPHYLL CONTENT, carotenoids and biomass were evaluated. G104 genotype had the highest catalase activity (1.75unit) and proxidase activity and for polyphenol oxidase G485 genotype exhibited the highest in 200mM treatment. Also the highest (93%) and the lowest (54%) reduction percentage of CHLOROPHYLL CONTENT were observed in G643 and G485, respectively. Results showed a high correlation between antioxidant enzyme activities and chlorophyll, so that genotypes with higher antioxidant activity had higher CHLOROPHYLL CONTENT and biomass. There was positive correlation between SALINITY resistance at germination stage and seedling stage under greenhouse conditions.
