果实可溶性糖的积累模式及其调控研究进展

Research Progress on Accumulation Pattern and Regulation of Soluble Sugar in Fruit

可溶性糖在果实中的种类及比例有所差异,这种差异主要受果实中糖的代谢贮运调控。重点综述果实糖代谢途径,不同果实可溶性糖积累类型包括直接积累型、淀粉转化型、中间积累型,以及果实糖含量主要调控因子包括遗传和环境等方面的研究进展,以期对未来果实品质改良和通过分子辅助育种手段选育高糖含量的果树新品种、新种质以及提质增效栽培研发有所借鉴。

Sugar is one of the core substances of fruit quality,the content and composition of soluble sugar are the key factors affecting the edible quality of fruit,especially the fruit sweetness and flavor.The types and proportions of soluble sugars in fruit are different,which mainly controlled by sugar metabolic pathways and transportation.This paper focuses on the sugar metabolism pathways,regulation characteristics and main regulating factors of sugar concentration based on different fruit soluble accumulation patterns,which has important guiding significance for fruit quality improvement,breeding varities of sugar abundant fruit by the pathway of molecular assistant breeding and the research of cultivation with the advantages of quality developed and efficiency enhanced.
