Effect of Different Countermeasures on the Growth of Summer Maize under High Temperature Stress
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.
