In this study, the Glycine max Jackson cultivar (the relatively drought-sensitive) and the Glycine soja BB52 accession (the drought-tolerant one) were used as the experimental materials. Effects of seed soaking with exogenous soybean isoflavones (daidzin or genistin) on seed germination, and seedlings photosynthesis, relative electrolytic leakage, content of thiobarbituric acid reactive substances , and anti-oxidative activities were investigated under drought stress conditions. The results showed that, treatments of seed soaking with daidzin or genistin could improve seed germination, and alleviate cell damage, enhance anti-oxidative activities and photosynthesis in drought-stressed seedlings, therefore displayed mitigated effects on soybean drought injury, especially for the drought-sensitive G. max Jackson cultivar. Thus seed soaking with exogenous soybean isoflavones may be a usable approach to enhance drought tolerance of cultivated soybean in practice.
