Analysis of Soluble Sugar Components and Contents in Extra-late/late Litchi Germplasm
The composition and content of soluble sugars in 6 extra-late/late litchi germplasm fruits were determined via high-performance liquid chromatography.The results revealed that the soluble sugars in extremely late maturing/late maturing litchi fruits were mainly composed of fructose,glucose,and sucrose.The fructose content accounted for 35.84% of the total sugar content,glucose content accounted for 30.27% of total sugar,and sucrose content accounted for 33.89% of the total sugar content.The coefficients of variation of fructose,glucose,and sucrose among the various substances were 7.26%,8.07%,and 13.45%,respectively.According to the ratio of reducing sugar to sucrose,both late maturing and late maturing litchi germplasms accumulate reducing sugars.Correlation analysis revealed that all sugar components in the fruit were positively correlated with total sugar.There was a highly significant positive correlation between the fructose and glucose contents,while there was a significant correlation between the glucose and total sugar contents.
