Abstract:

Rice grain filling is the most important physiological process of grain formation, and it is also the decisive stage of grain weight, yield and rice quality. To fully understand the intrinsic characteristics of rice grain filling and promote high-yield cultivation and good quality breeding of rice, the biological characteristics, physiological mechanism, endogenous hormones, enzyme activities, gene, proteins and environmental factors affecting rice grain filling are summarized. Meanwhile, the research direction of rice grain filling is discussed, and the possibility of studying grain filling mechanism in molecular biology such as proteomics, genomics and gene expression is also put forward.

Key words: rice, grain filling, endogenous hormones, enzyme activity, gene and protein, influence factors, mechanism
