Effect of protein and lipid in rice on starch physicochemical characteristics, difference between the region of non-chalkiness and chalkiness of rice, dynamic variation of cell structure and CaM distribution on rice spike were expounded in this study. It was found that protein and lipid in rice had important effect on starch gelatinization, there were distinct differences between the region of non-chalkiness and chalkiness of rice, vascular bundle system in rice spike was changed during grain filling, difference quality of different position of rice spike was more distinct in dense spike rice for more powerful vascular bundle system, the development of rice seeds was corresponded to pericarp development, difference quality of different position of rice spike was also related to transport function of rachilla besides activity of "source", and calmodulin relative activity was closely related to grain filling velocity and enginery properties.
