In order to study the salinity stress effects resulted from sodium chloride on germination, vegetative growth, elements concentration and proline accumulation in five canola cultivars, two experiments were conducted. They were carried out in a germinator and greenhouse at the Research Station of the Faculty of Agriculture at Baku State University. The first factor of the experiment was canola cultivar - 'Licord', 'Fornax', 'Okapi', 'Elite', 'SLM046', and the second factor was salinity stress level: 0, 50, 100, 150 and 200 mM NaCl in a germination experiment and 0, 75, 150, 200, 250 and 300 mM NaCl in a pot experiment. The results showed that different salinity stress levels had a significant effect on germination percentage, germination speed and shoot and root length. In the pot experiment, there was a significant effect on plant height, leaf area, dry matter, elements concentration, proline accumulation and seed yield due to salinity stress. It was observed a significant effect of the cultivar on investigated traits except for leaf area. An increase in salinity level decreased all variable except sodium, chlorine and proline concentration. Sodium, chlorine and proline concentration were increased by salinity stress. The response of canola cultivars was different at germination and vegetative growth stages. In the germination experiment, the most sensitive and most tolerate cultivars were 'Elite' and 'Licord', respectively. However, in the pot experiment, 'Licord' cv. had the least growth rate and yield than 'SLM046' and 'Okapi'. Significant differences between these cultivars were observed. It seems that the evaluation of germination properties is not useful for the assessment of salinity tolerance of canola cultivars.
