Abstract: Sugar metabolism is an important basis for the form of fruit color, flavor and the metabolism of other nutrients, it was a major factor for the determining of the quality and commercial value of the fruit. The regulation of sugar metabolism is particularly important on the post-harvest fruit quality and the regulation of ripening and senescence. This paper reviews the recent research progress at home and abroad in the regulation of sugar metabolism in post-harvest fruit, included physical control technology, chemical control technology, and hormone regulation and other three areas, therefore, provided certain theoretical reference for the in-depth research of fruit sugar metabolism and improvement of the quality.

Key words: sugar metabolism, postharvest fruit, soluble solids, sucrose, fructose, glucose
