摘　　要：小麦灌浆主要是有机物合成并贮存在籽粒内的生理过程,是“源-流-库”相互作用的结果。小麦不同穗位籽粒因发育及形成时间顺序不同,造成不同穗位籽粒的淀粉品质存在差异。为充分了解小麦籽粒淀粉合成与积累的内在调控机制,本文归纳了淀粉合成途径中原料供给与调控,总结了淀粉合成关键酶及其编码基因的功能,分析了库容和库活性对小麦籽粒淀粉合成与积累的效应,以期为更深入研究小麦籽粒淀粉品质形成过程及其遗传改良提供参考。Grain filling of wheat is mainly a physiological process of organic matter synthesis and storage in grains,which is a result of the interaction among“source-flow-sink”.However,the starch quality of wheat grains at different panicle positions is different due to different development and formation time sequence.In order to fully understand the internal regulation mechanism of starch synthesis and accumulation in wheat grains,we summarized the supply and regulation of raw materials,the functions of key enzymes for starch synthesis and their coding genes,and analyzed the regulation of sink capacity and sink activity on starch synthesis and accumulation in wheat grains in the starch synthesis pathway.This paper provides relevant knowledge for further research on the starch formation process of wheat starch and also as a reference for crop genetic improvement.
