Abstract The present thesis focused on determination of the effect of salinity on germination and seedling growth of some canola varieties. Factorial experiments were conducted in randomized complete block design with replications including 4 canola cultivars (PR44W29, NK LINUS, DK EXTORM, ES NEPTUNE) and 6 salinity levels (0, 5, 10, 15, 20, 25% EC generated through addition of 0, 2.75, 5.72, 9, 12.45 and 15.70 g/l NaCl, respectively). Following 7 day germination tests, number of germinated seeds were counted and length of whole plant, shoot and root fresh and dry weights were measured. The highest germination rate (85.5%) was obtained from 0% EC salinity level of DK EXTORM and the lowest (1.5%) from 25% EC level of NK LINUS variety. The differences in germination rates of the experimental groups were not found to be significant (P>0.05). The highest seedling height (74 mm) was obtained from 5% EC level of NK LINUS variety and the lowest from 25% EC level of PR44W29 and DK EXTORM varieties (P<0.05). The highest root length (64.1 mm) was observed in 5% EC level of NK LINUS variety. However, because of high salinity levels, ES Neptune and DK EXTORM and PR44W29 varieties did not achieve root development at 25% EC salinity level (P<0.05). The highest fresh weight (125.9 g) was obtained from 5% EC level of NK LINUS variety and the lowest (0 g, all seedlings were dead) from 25% EC level of ES Neptune and DK EXTORM varieties (P<0.05). The highest dry weight (5.5 g) was obtained from 20% EC level of NK LINUS variety. Dry weights were not able to be measured in ES Neptune and DK EXTORM varieties since seeds died at high level salinity levels. The lowest dry weights (2.1 and 2.7 g) were obtained from 25% EC level of DK EXTORM PR44W29 varieties, respectively. In general, decreasing germination, seedling length, fresh and dry weights were observed with increasing salinity levels (from 0% EC to 25% EC).
