This study aims to quantify the effect of different response measures on high temperature in summer maize by Meta-analysis method with no measures as control.The results showed that,the selection of heat-resis-tant varieties had the best effect of enhancing summer maize yield.Compared with the heat-sensitive varieties,the selection of heat-resistant varieties had the most positive effect on the pollination and setting capacity.The applica-tion of plant growth regulators mainly affected yield and activities of oxidase,while fertilization mainly affectednet photosynthetic rate.The selection of heat-resistant varieties is the most effective approach to alleviate the heat dam-age of summer maize.Additionally,applying plant growth regulators,fertilizing,and adjusting the sowing period can further alleviate the adverse effects of heat stress.
