Effects of Sowing Date and Planting Density on Yield and Quality of Winter Wheat

The effects of sowing date and plant density on grain yield and quality of the winter wheat Xindong 24 were studied. The results showed that (1) with the delay of sowing date in late its yield ear number ,1000-kernel weight and kernel numbers per ear all are decreased.(2) with the delay of sowing date,the protein content ,wet gluten content and dough development are increased.With increasing of plant density, protein content,wet gluten content and stable time all would be first increased then decreased.
