涝渍胁迫对植物生长的影响及其化学调控技术

Effects of Waterlogging Stress on Plant Growth and Its Chemical Control Techniques

涝渍胁迫是农业生产的限制因子之一。涝渍胁迫条件下植物细胞感受到缺氧信号,并做出适应性调节,如产生厌氧蛋白质等。同时植物细胞的代谢途径也发生改变,其突出的特征是以无氧发酵代替有氧呼吸。涝渍胁迫也可以诱导植物生长形态的改变,如通气组织的形成和不定根的产生等。从植物的生长形态、生理代谢、内源激素等方面概述了涝渍胁迫对植物产生影响的研究现状及其进展。指出了目前对植物受涝渍胁迫进行化学调控等方面存在的问题,提出了今后深入研究的方向。

Waterlogging stress is one of the main limit factors for agricultural production.Under waterlogging conditions,plant cell receives the anoxia signal and thus gives an adaptive response,such as the production of anaerobic polypeptides.At the same time,the metabolic pathway of plant cell is changed and the aerobic respiration is replaced by anaerobic fermentation.The plant morphology is also changed under anoxia,such as the formation of aerenchyma and adventitious roots.The research progress of effects of waterlogging on plant morphology,physical metabolism and hormones.The problems of chemical control of plants subjected to waterlogging stress,as well as the possible further studies were pointed out.
