Abstract: The research in crop low temperature chilling injury was extensive and in-depth over years at home and abroad. The abroad research on chilling damage mainly focused on the mechanism of crop cold damage,but the less research on chilling damage indexes and chilling damage monitoring. Therefore in this paper the indexes of low temperature damage were summarized, which have been determined for different crops and different areas in China for many years. Its applicability and advantages or disadvantage also were analyzed. The basis for selecting the suitable chilling injury index under different conditions was provided in this paper.
