Abstract: The study of crop drought tolerance is of great significance for agricultural production. This paper summarized the advances of physiologic and biochemical indexes, which included the photosynthesis, the respiration, the osmotic regulation, the plant endogenous hormones and antioxidant and defense system, in the research of drought tolerance in crop. Furthermore, it clarified the relationship between the variation of physiological and biochemical indicators and the strength of crop drought tolerance, and provided a theoretical basis for future deeper study of crop drought tolerance.
