Abstract: The physiological characteristics of the grain formation stage of winter wheat (GFSWW)in clay loam,loam and sandy loam in Yu Dong Plain area had been studied with pool culture method.The results indicated that NPR,chlorophyll content,transpiration rate,root actvity,LAI etc of winter wheat given a obvious differences in three kinds of soils.Those differences influenced grain filling of wheat and formation of yield.In sandy loam,owing to the physiological indexes of GFSWW decreased rapidly,the duration of grain filling shortened and the 1000 kernel weight decreased.But in clay loam the results of the physiological indexes went by contraries.In loam the variations of the physiological indexes were between them.In addition,the wheat flag leaves in three kinds of soils all showed the phenomenon of “middy depression”of photosynthetic rate.
