Abstract:
This study was conducted with drought sensitive variety HN65 and drought resistant variety KX9, sand culture and PEG-6000 were used to simulate drought stress to research on the effect of exogenous ABA,JA and SA on soybean growth under drought and re-watering. The result showed that, three exogenous plant hormones all could decrease MDA and hydrogen peroxide content in soybean leaf, which was bad for accumulation of soluble sugar and soluble protein content, protecting soybean from drought and re-water. And ABA showed more significant promotive effect than SA and JA.Three exogenous plant hormones all could alleviate the inhibition of drought on morphological index, JA had more promotive effect than ABA and SA for drought-sensitive soybean variety HN65, and SA had more promotive effect than ABA and JA for drought resistant variety KX9. Three exogenous plant hormones all could decrease drop flower rate of both varieties especially HN65.
