摘要
明确了干旱胁迫对作物生长后效影响的概念,探讨了它与滞后或时滞的区别。通过大量文献综述,在比较微观的生理层次上分析了干旱胁迫对作物生长后效影响的因素,包括干旱胁迫程度、持续时间、胁迫时期、胁迫发生速率及作物种类。探讨了干旱胁迫对作物生长后效影响的机制,指出了需要进一步研究的方向。
The paper clarifies the concept of aftereffect of water stress on crop growth, and examines the difference between the aftereffect and the delayed effect or timelag effect. Under the microscopic level of physiology, through citing lots of literatures, the factors affecting the aftereffect, including stress degree, stress duration, stress stage, stress happening speed and plant types, are analyzed. The paper also examines the mechanism of aftereffect. Finally, the direction for further study is pointed out.\;
