Abstract: Multi-indexes, which can representatively reflect plant Heat-resistance, were applied to valuate the heat-resistance of 4 varieties alfalfa with different fall dormancy classes in this experiment. The results of heat injury and recovery index showed that WL- 525HQ is higher, and WL-232HQ is poorer in heat-resistance. Based on the analysis of subjection function, the order of heat-resistance for the 4 alfalfa varieties were arrayed as the following: WL-525HQ〉WL-414HQ〉WL-323HQ〉WL-232HQ, the varieties with high class of fall dormancy performed higher heat-resistance.
