高温胁迫影响玉米生长发育的研究进展

摘要:温度是影响玉米生长和发育最重要的生态因子之一。近年来,作物生育期间高温天气发生频率增加、持续时间延长。高温胁迫对作物生长发育及产量形成的影响日趋严重,已经引起科研工作者的关注。研究高温胁迫影响玉米生长发育的机理并制定防御措施,对玉米高产稳产具有重要意义。本文系统阐述了高温胁迫对玉米根系、叶片、雌雄穗发育、籽粒灌浆、抗氧化系统、内源激素含量及平衡等6个方面的影响,以期为深入了解高温胁迫限制玉米生长发育的机理,制定应对高温胁迫的预防措施提供参考。 英文摘要: Abstract: Temperature is one of the most important ecological factors affecting the growth and development of corn. In recent years, the frequency of high temperature weather during crop growth has increased and its duration has prolonged. The effects of high temperature stress on crop growth and yield formation have become increasingly serious and have attracted the attention of researchers. It is important to study the mechanism of high temperature stress on maize damage and to develop defense measures for the stability of corn production. This paper systematically expounds the effects of high temperature stress on maize roots, leaves, male and female ear development, grain filling, antioxidant system and endogenous hormone content and balance, for the understanding of the mechanism of high temperature stress limiting maize growth and development, and provide a reference for the prevention measures against high temperature stress. 查看全文
