Abstract: To understand the carbohydrate changes of‘Kyoho’grape during dormancy and dormancy-release, in vitro 1 year giant peak grape branches were taken as the material in hydroponic monitoring of the carbohydrate changes during grape dormancy. With liquid chromatography methods, the content of sucrose, glucose and fructose, soluble sugar and starch, and cellulose were tested. The results showed that the deep dormancy of grape was on January 6th, and the dormancy was released on February 5th. The content of glucose, fructose, soluble sugar and starch increased with dormancy deepening, and the content of glucose, fructose, sucrose and soluble sugar decreased after dormancy- release, but the content of sucrose increased with dormancy releasing. The change of cellulose was not significant. The content of fructose was positively correlated with glucose in various organs. The soluble sugar content in buds, phloem and xylem showed significantly positive correlation between the two poles.
