Abstract: In order to study the effect of salt-ion content on the growth of rapeseed, ‘Yangyou 9’ and ‘Suyou 211’ as tested varieties were planted under low salt level (salt-ion content was 2.978g/kg ) and high salt level (salt-ion content was 4.900g/kg) in 2015-2016. Dry matter weight, agronomic characters and seed qualities were tested through sampling at maturity. Results showed that with increasing salt-ion contents the dry matter amounts of whole plant and different organs decreased significantly. The yield decline range of ‘Yangyou 9’ and ‘Suyou 211’ in high salt level was 24.14% and 27.83% compared with low salt level, respectively. The dry matter amounts of root declined have a biggest decline in different organs, and the decline range of ‘Yangyou 9’ and ‘Suyou 211’ in high salt level was 34.52% and 39.69% compared with low salt level, respectively. However, the effects of stem and branches dry matter amounts by different salt-ion contents were the least, and the decline range of two varieties in high salt level was 9.46% and 12.93% compared with low salt level, respectively. With increasing salt-ion contents, the proportion of dry matter distribution in stem and branches increased significantly, and the proportions of other organs decreased significantly. With increasing salt-ion contents, the plant height and number of pods decreased, and there was no significant difference in number of seeds of per pod and 1000-seed weight between different salt-ion content treatments. With increasing salt-ion contents oil content increased, and protein content decreased significantly.
