Abstract：Taking Chinese cabbage‘Jinyu 80’and‘99-2’as experimental material，studied the effect of different EMS concentration treatments on seed germination，seedling growth，and major biochemical indexes of both seed and seedling．The results showed that within the scope of 0-1.0% concentration，the germination potential and germination rate of Chinese cabbage seeds were decreased，the seedling root tip and cotyledon edge gradually turned to brown．The seedling surviving rate was decreased gradually，and the conductivity value of seed leachate and MDA contents in seed and seedling were all increased gradually．The EMS effect on SOD and POD activities of seed and seedling were expressed as low concentration with promotion，and high concentration with inhibiton．The optimal EMS concentration for Chinese cabbage seed treatment was ranged from 0.4%-0.6%．
