Progress in Research on the Effects of Heat and Drought on Maize Growth, Development, and Yield Composition

摘要:

本文阐述了高温干旱对玉米生长发育及产量构成影响的研究进展，包括花期高温、平均气温升高与夜间气温升高对玉米生长发育的影响、作物模型对高温影响的模拟、干旱胁迫对玉米开花吐丝及产量构成的影响、干旱胁迫条件下玉米吐丝时间及产量构成的模拟、复合高温干旱事件对玉米产量构成的影响等方面，并对未来研究重点进行展望。

Abstract:

This article systematically reviews the current research progress on the effects of heat and drought on maize growth, development, and yield composition. This includes the impacts of heat(anthesis heat stress, rising average temperature, and increase in nighttime temperature) on maize growth and development, the simulation of heat effects using crop models, the effects of drought stress on the anthesis-silking intervals and yield composition, the simulation of anthesis timing and yield composition under drought stress, and the combined effects of heat and drought stress on maize yield composition. This article also prospects future research focuses.
