Effects of exogenous nitric oxide on growth of cotton seedlings under NaCl stress

In the present investigation, the role of sodium nitroprusside (SNP, a donor of NO) in inducing salinity tolerance (100 mM NaCl) in cotton was studied. Salt stress reduced the values of photosynthetic attributes and total chlorophyll content and inhibited the activities of nitrate reductase. Further...
