Abstract:: Taking ‘Luoyu 201’radish seed as material，radish seeds were treated with different concentration (0 mg/L，5 mg?L-1，10 mg?L-1，20 mg?L-1，30 mg?L-1，40 mg?L-1) of GA3.The effect of GA3 on germination and seedling growth of radish was studied.The results showed that the germination of radish seed and the growth of seedling were significantly promoted after the seeds treated with GA3.The root length，root activity，plant height，the chlorophyll content and soluble protein content of the radish seedlings were increased，while the content of MDA was decreased.The best GA3 concentration was 20 mg?L-1 for seed germination，and was 10 mg?L-1 for seedlings.
