【Abstract】 The treatment of wheat seeds by drought resistant agent could accelerate seed germination and seedling growth under drought stress , and also 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 drought resistant agents developed by the research group of wheat water saving technique in Anhui Technical Teachers College was more effective更多还原
