Abstract:: In the experiment，the effects of different concentrations (0，0.3，0.6，0.9，1.2，1.5 mmol?L-1) of indole-3-acetic acid and salicylic acid on the physiological characteristics of radish seedlings under NaCl stress were studied.The results showed that there were significant changes in the physiological indexes of radish seedlings under NaCl stress.When the seedlings were treated with the proper concentrations of indole-3-acetic acid and salicylic acid，the reducing sugar content，proline content，MDA content and relative conductivity significantly decreased，while the chlorophyll content increased significantly，which had a certain role in mitigation to salt damage.However，if the concentration was too high，there was a new stress injury.According the results，the optimal concentration of indole-3-acetic acid was 0.9 mmol?L-1，and the best concentration of salicylic acid was 0.6 mmol?L-1.
