The germination characteristics and seedling growth of 25 rapeseed cultivars under six levels of salt (NaCI) stresses including 0, 3, 6, 9, 12 and 15 ds/m were studied. The germination percentage of the rapeseed cultivars did not decrease significantly with increasing salt levels up to 12 ds/m. However, the required time for germination increased with increasing the salt percentage in the growth medium. A positive and significant relationship between germination percentage and speed rate and also between germination percentage and radicle length at the highest level of salt stress was observed. Consequently the salt tolerant cultivars had a higher seed germination and speed rate and produced a higher radiçle length as compared to other cultivars.
On the basis of seed germination and speed rate parameters the rapeseed cultivars were categorized into three groups. According to the responses of different germination parameters to salt stresses it was concluded that the optimum electrical conductivity of salt solution for rapeseed germination would be in the range of 3-6 ds/m.
