Pot experiments were conducted by simulate high temperature stress during the flowering stage in phytotron, to study the effect of chemical regulators on rice in high temperature stress. The results were as follows: alleviative effect of chemical regulators on rice only works when the chemical treatments were spraying before high temperature stress, it was invalid after the high temperature stress. Among these chemical regulators, the trans-abscisic acid performed the best alleviative effect, followed by Methyl Jasmonate and KH2PO4. The alleviative effect of chemical regulators is mainly through the improvement of seed setting rate to ease the yield loss of high temperature stress. The effect of chemical regulators is just alleviative, it can not fully recover the yield loss in high temperature stress.
