Abstract

This research was carried on to evaluate the response of rapeseed varieties to salt stress. In this experiment growth response of three rapeseed varieties (Fornex, Consoul and Okamer) in four salinity levels (0, 40, 80 and 120 mmol NaCl) was investigated using a factorial arrangement of factors in a complete randomized block design with three replications. Results incicated that in the highest salinity level shoot dry matter of Fornex and Okamer was decreased, respectively by 58 and 82 percent compared to control condition. under highest salinity, Fornex verity had lowest leaf Na+ and Malondealdehaid concentration and the highest leaf K+ concentration and Peroxidase activity.
