5个大麦品种对开花期涝害的适应性研究
Study on the WaterIogging Adaptation of Five BarIey Varieties During FIowering Stage
摘要
Abstract
A pot Experiment simulating waterlogging was conducted with five barley varieties to investigate the growth status and waterlogging adaptability of barley cultivars during flowering stage,and to provide basis for screening of barley varieties with waterlogging tolerance.The effects of waterlogging on the plant height,yield,Chlorophyll SPAD value and some nutri-ents of five barley varieties were studied.The five barley cultivars showed high resistance to waterlogging during flowering stage.The plant height,theoretical seed yield,theoretical straw yield,and crude protein of Huadamei 9 were the highest, which showed good resistance against waterlogging.The chlorophyll SPAD value and chlorophyll content of barley plant were reduced by waterlogging,so its photosynthesis was decreased.But the chlorophyll content in Huadamei 9 recovered faster after waterlogging.Therefore,Huadamei 9 is a suitable variety to cultivate in winter idle fields where may be water-logging during March to May in the south.关键词
