Abstract
- Twenty chickpea cultivars were germinated under control and different levels of salt stress induced by sodium chloride and out of these, three desi (PDG 3, GL 12003, C 106) and two kabuli (FLIP-08-125-C and GLK 28127) cultivars were selected on the basis of embryonic axis growth, biomass, salinity stress tolerance index. Antioxidative enzymes, non-enzymatic antioxidants proline and proline metabolizing enzymes and free radical scavenging activities were estimated in embryonic axes of these selected cultivars under control and salt stressed conditions. Higher activities of catalase and Δ1-pyrroline-carboxylate synthetase (P5CS) and sustained activities of superoxide dismutase (SOD) and ascorbate peroxidase (APX) in embryonic axis along with higher SOD and glutathione reductase and maintained APX in cotyledons might be mediating salt stress tolerance in kabuli cultivar FLIP-08-125-C. Higher proline content, enhanced P5CS activity and decreased proline dehydrogenase activity in embryonic axis along with higher free radical scavenging activities both in cotyledons and embryonic axis in desi cultivar PDG 3 might be mediating salt stress tolerance by maintaining osmotic balance and reducing oxidative damage.
