摘要
综述了涝渍胁迫对植物的生长形态、生理生化变化等方面的影响,论述了植物抗涝的机制,总结了植物涝渍胁迫研究的方法,阐述了植物涝渍胁迫研究方面存在的问题,提出了利用生物技术克隆耐涝基因,通过转基因技术培育抗涝性植物新品种,同时加强植物的田间管理等提高植物抗涝性的途径。
In this article, effects of waterlogging stress on growth and morphology, and physiology and biochemical chan- ges of plants were summarized, the waterlogging tolerance mechanism of plants was discussed, and the research methods on waterlogging stress were summarized. Moreover, the existing problems on waterlogging stress researches of plants were described, and then the effective ways on improving the waterlogging resistance of plants were put forward, such as cloning waterlogging resistance genes by biotechnology, breeding new varieties with waterlogging resistance by transgenic technolo- gy and strengthening field management of plants, and so on.
