摘　　要：湿涝害是作物生产过程中主要的非生物逆境之一,它决定了作物分布,限制了作物的生长发育和产量。作物遭受湿涝害时,其根系和地上部会做出不同的响应,分别从分子、生理生化和形态结构上适应湿涝害,确保作物的生长发育。从土壤湿涝害如何使根尖死亡、根系和地上部如何适应湿涝害以及作物耐湿涝的遗传研究等方面,综述了作物的耐湿涝性研究进展,并提出和讨论了有关该领域有待进一步开展的研究工作。Stress on crops imposed by soil waterlogging and submergence constitutes one of the major abiotic constraints on growth, distribution of species and agricultural productivity. When crop plants are subjected to soil waterlogging and submergence, their root and shoot systems respond differently. A wide range of molecular, physiological, biochemical and morphological adaptations supports the growth and reproductive success of crop plants. This article reviewed recent work on crop re- sponses to waterlogging and submergence stress, which addressed the questions that how root tips were killed and that how roots and above-ground shoots survived under waterlogging and submergence. The genetic analysis of waterlogging and sub- mergence tolerance was also reviewed. Some suggestions in this field were pointed out.
