Abstract

Salinity is one of the major stresses in arid and semi-arid regions causing adverse effects at physiological, biochemical, and molecular levels, limiting crop productivity. In this research, three canola cultivars (Licord, Talayeh, Zarfam) were compared at 5 salinity levels (control, 50, 100, 150 and 200 mM) for their catalase, guaiacol peroxidase, superoxide dismutase activity,proline and yield in a completely randomized design with 3 replications. In our study, we found that NaCl concentrations greater than 150 and 200 mM caused the irreversible disorders. Increased salt concentrations led to significant changes in the levels of antioxidative enzymes and proline in three canola cultivars. Also, yield rates in three varieties decreased in the presence of NaCl concentrations.
