Abstract
A pot experiment was conducted to appraise the differences in salinity tolerance in two canola cultivars (Shiralec and Dunkeld). The experiment was laid out in completely randomized design with five replications. Four salinity levels [0, 120, 150, and 180 mM sodium chloride (NaCl)] were used in this study. Salt stress caused a marked decrease in plant fresh and dry masses, photosynthetic pigments, and anthocyanins and increase in malondialdehyde (MDA), hydrogen peroxide (H2O2), and leaf phenolics. We have observed that salt tolerance ability of cv. Shiralec is greater than that of Dunkeld in terms of lower salt-induced decline in fresh and dry masses, photosynthetic pigments, lower MDA, H2O2 contents, and greater leaf phenolics.
