Effects of Waterlogging Stress on Nitrogen Metabolism and Yield in Winter Wheat at Booting Stage
Effects of waterlogging at booting stage on N nutrition and yield were studied from 1998 to 2000 by applying simulation waterlogging method.The results showed that waterlogging at booting stage significantly influenced N nutrition absorbtion content,and reduced the total chlorophyll content,net photosynthesis rate of flag leaf,the grain weight,and economic yield finally.
