【Abstract】 It was shown in the testing results of the culture of rice seeds germination and seeding growth under NaCl stress that the germination of the rice seeds was inhibited under 9g ·L -1 NaCl stress. While under the stress of NaCl, when the SA with the concentration of 0.02, 0.05, 0.10, 0.15 and 0.20g·L -1 was added respectively, the germination rate, germination index, vital index, bud length and root length were all reduced, but the MDA content of rice seedling was increased. The SA with the concentration of 0.02, 0 .05, 0.10, 0.15 and 0.20g·L -1 had not alleviated the inhibition of 9g·L -1 NaCl.更多还原
