Ameliorative effects of nitric oxide on growth, physiology and biochemistry of chickpeaplants under salinity stress

Salinity is one of the major environmental constraints affecting agriculture in regions world. This study was conducted to evaluate effect exogenous nitric oxide (NO) treatments on two chickpea cultivars (Cagatay and Inci) under salt stress conditions. Different NO doses (0. 75 100 μM sodium nitroprusside (SNP)) as an source were applied plants grown saline (presence 50 mM NaCl) nonsaline In this study, plant shoot fresh dry weight, root chlorophyll a, b, total chlorophyll, reading value (CRV), relative water content (RWC), electrical conductivity (EC), malondialdehyde (MDA), hydrogen peroxide (H2O2), antioxidant enzyme activity [superoxide dismutase (SOD), peroxidase (POD), ascorbate (APX)], K/Na Ca/Na ratio examined. Plant growth, RWC, negatively affected by salinity conditions but treatment improved parameters. EC, H2O2, MDA increased with while decreased searched ratios NaCl treatments. Although response similar general, Inci found be more sensitive than Cağatay cultivar. The present revealed that supported seedlings against regulating uptaking mineral elements, activity, RWC.
