摘要
在我国长江中下游地区的棉花种植区域,由于受到长时间梅雨季和强降雨的影响,棉花在生长发育时期容易受到涝害胁迫,棉花的生理生化特征和分子机制都发生了变化,植株地下部分缺氧使地上部分的干物质合成受阻,导致棉花产量和品质严重下降,这成为当前长江流域棉花产业稳定的一大问题。综述了涝害对棉花生理生化特征以及品质产量的影响,并进一步分析了棉花耐涝的分子机制,为棉花耐涝种质资源筛选和新品种选育提供了理论依据。
In the cotton growing areas in the middle and lower reaches of the Yangtze River,due to the influence of heavy rainfall in the plum rain season for a long time,cotton suffered waterlogging stress during the growth and development period.The physiological,biochemical and molecular mechanisms of cotton have changed.The hypoxia in the underground part of the plant blocked the synthesis of dry matter in the aboveground part,resulting in the serious decline of cotton yield and quality,this had become a major problem of cotton industry stability in the Yangtze River Basin.The effects of waterlogging on the physiological and biochemical characteristics,yield and quality of cotton were summarized.The molecular mechanism of waterlogging tolerance of cotton was further analyzed,which provided theoretical basis for the selection of waterlogging tolerant germplasm resources and the breeding of new cotton varieties.
