摘　　要：淀粉是水稻(Oryza sativa)胚乳的主要贮藏物质,其积累过程影响植物后续的生长发育。作为人类从水稻中摄取的主要营养物质之一,淀粉在水稻中的合成和积累过程备受关注。该文综述了蔗糖从韧皮部卸载、淀粉合成关键酶以及激素等内源因素影响淀粉合成和积累的最新研究进展,并指出了胚乳淀粉积累过程尚未解决的问题,旨在为后续深入研究提供参考思路。Starch is the major storage material of rice(Oryza sativa)endosperm,and its accumulation process affects the subsequent growth and development of plants.As one of the main nutrients absorbed by human beings from rice,the synthesis and accumulation process of starch in rice has attracted increasing attention.This review mainly discusses the latest progress of endogenous factors affecting starch synthesis and accumulation,such as sucrose unloading from phloem,key enzymes of starch synthesis and hormones,and points out the unsettled questions in the field of endosperm starch accumulation to provide some reference ideas for further research in the future.
