摘要
淹水是影响植物生长发育的一种重要的非生物逆境胁迫,严重影响植物的形态结构、抗氧化系统、呼吸作用、光合作用和激素代谢,从而降低产量和品质,甚至造成绝产或大面积死亡。而植物遭受涝害后,会积极调整自身形态结构、生理代谢和分子机制以缓解涝害产生的不良影响,减少涝害损失。本文主要从形态学、生理学和分子生物学这三个层面,综述了植物对淹水胁迫的响应机制,旨在对植物抗涝性研究提供参考,并为淹水胁迫的进一步研究提供新思路。
Flooding is an important abiotic stress that affects the growth and development of plants,which can seriously affect the morphological structure,antioxidant system,respiration,photosynthesis and hormone metabolism of plants,resulting the reduction of the yield and quality,and even causing a large area death of plants.After waterlogging,adaptive response like morphological structure,physiological metabolism and molecular mechanism occurs to alleviate the adverse effects of waterlogging and reduce waterlogging losses.In this paper,the response mechanism of plants to waterlogging stress was summarized from the three aspects of morphology,physiology and molecular biology.The aim of this paper was to provide a reference for the study of waterlogging resistance of plants and to provide new ideas for the further study of waterlogging stress.
