چکیده
to study the effect of salinity on physiological and morphological traits of chickpea in 2010 at faculty of agriculture and natural resources, university of tehran with seven chickpea genotypes. two experiments design was rcbd with 3 replications and 5 levels of salinity stress (ctrl, 200, 150, 100, 50 mm) for laboratory experiment on germination indices and greenhouse experiment on physiological and biochemical traits. 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. highest and lowest of germination percentage were obtained in 200 mm treatment for g485 and g456 respectively. g485 had highest vigor index in response to 200 mm treatment. the pea genotypes of biomass was significantly affected by salinity levels, , so the stress level of 50 mm g485 with 3.8 g had the highest levels of the index.in second study, we evaluate activities of catalase, peroxidase, polyphenol oxidase, total chlorophyll and carotenoids and biomass. g104 genotype had highest of catalase activity (1.75unit) and highest of proxidase enzyme activity and polyphenol oxidase were obtained by g485 genotype in 200mm treatment. also highest (93%) and 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 resistant to salinity at seedling stage of germination and greenhouse condition.

Germination is one of the most effective processes to improve the quality of legumes. Vitamins and some other compounds that might be considered beneficial as antioxidants, often change dramatically during the course of germination. Antioxidants might be defined as compounds which are capable of preventing, delaying or retarding the development of rancidity or other flavor deterioration in food...
