Accumulation and Translocation of Dry Matter before Flowering and Their Effects on Yield in Different Winter Wheat Varieties
Yan Shuping
Abstract：In order to explore the relationship between yield formation and dry matter accumulation and translocation in vegetative organs before flowering in different wheat varieties,and provide theoretical basis and technical support for the current wheat breeding,6 wheat varieties were selected for the experiment.The results showed that the biomass before the over -wintering period was crucial to the biomass accumulation before flow-ering.It was necessary to ensure the amount of effective accumulated temperature before the over -wintering period for increasing the dry matter accumulation in vegetative organs,so as to accumulate more nutrients.The dry matter accumulated more before flowering could contribute more to kernel,and the dry matter transfer rate would be higher,which was crucial to the final biomass.
