The output rate and transformation rate of dry matter in stems can be calculated as follows:the output rate of dry matter in stems=(the mass of dry matter in stems at the full heading stage-the mass of dry matter in stems at the maturation stage)/the mass of dry matter in stems at the full heading stage×100%,and the transformation rate of dry matter in stems=(the mass of dry matter in stems at the full heading stage-mass of dry matter in stems at the maturation stage)/the mass of an ear×100%[4].According to Table 1,the amount of dry matter transported to grains of Yugu 18from the full heading stage to the maturation stage was 45.3%higher than that of Jigu 19,and the transformation rate of dry matter in the stems of Yugu 18 was 11.7%higher than that of Jigu19.It indicates that Yugu 18 had good coordination after heading,and can transport dry matter from its stems to grains.
