【Abstract】 The treatment of wheat seeds by drought resistant agent could accelerate seed germination and seedling growth under drought stress, and so increased the rate of emergence and the ratio of root to canopy. After treatment by drought resistant agent, the indexes of physiology and biochemistry of wheat seedling were higher than those of ck, for this reason, the seedling could grow normally under water deficiency. The results showed that the effect of the rate of emergence on 8h pretreatment and 2% mixedness is the best,is 94%,than those of CK.更多还原
