The quality of rice grain is characterized by the component, structure and accumulation of starch.
水稻稻米淀粉的组成、结构与积累是稻米品质与产量的决定因素。
Therefor, the different accumulation and remobilization pattern of carbon and nitrogen in vegetative organs may be one of the major reasons for different grain protein and starch contents.
因此，营养器官碳、氮积累与分配的差异可能是小麦籽粒蛋白质和淀粉含量差异的重要原因之一。
The grain filling rate, grain filling percentage, grain weight and starch accumulation rate were positively and significantly correlated with the SuSase activity in grains.
籽粒灌浆速率、籽粒充实率、粒重和淀粉积累速率与蔗糖合酶活性呈显著正相关。
