干旱胁迫对作物生长后效影响的研究现状

Present situation of study on after-effect of water stress on crop growth

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 aftereffect of water stress on crop growth, and examines the difference between the aftereffect and the delayed effect or timelag effect. Under the microscopic level of physiology, through citing lots of literatures, the factors affecting the aftereffect, including stress degree, stress duration, stress stage, stress happening speed and plant types, are analyzed. The paper also examines the mechanism of aftereffect. Finally, the direction for further study is pointed out.\;
