Abstract: The presented work studied the physiololgical base of repeated drought method.The paper illustrated that the repeated drought method can fully reflect the drough resistance of crops or varieties by physiological responses of drought resistant varieties in different degree,and the relationship between water supply and demand in soil and plant.The survival rate after undergoing the repeated drought is a comprehensive result of the drought reaction of crops or varieties.It can represent the drought resistance of the tested varieties.This paper also studied the appraisal of drought resistance of wheat varieties in later growing stages.The result of repeated drought method shows the same as that in the field.

Key words: Crop, Drought physiological response, Soil water, Survival rate
