Effects of Waterlogging at Booting Stage on Accumulation and Distribution of Dry Matter in Winter Wheat
Experiments by column culture from 1997 to 1999 were carried out at the Experiment Farm of Anhui Agricultural University.The major results were as follows:waterlogging at booting stage speeded up the declination of dry weight of leaf ,stem, sheath, ear and root system,the influences upon dry matter accumulation,transportation and distribution were significant,and the grain weight and yield decreased finally
