- Abstract
【Objective】 The fruit quality characteristics of two major mango varieties(Tainong and Guifei)from four main mango producing regions(Sanya,Ledong,Dongfang,Changjiang)of Hainan were explored,in order to provide the referential basis for quality evaluation and cultivar selection of mango fruit. 【Method】 Seventy-six mango samples were collected. And 13 quality indicators of mango samples,including single fruit mass,fruit shape index,edible rate,soluble sugar content(SSC),sucrose(Suc),fructose(Fru),glucose(Glu),sweetness value,soluble solids(TSS),vitamin C (Vc),total acid(TA),sugar acid ratio(RST),TSS-acid ratio(RTT)were determined by 2,6-dichlorindophenol titration, acid-base titration,HPLC and other methods. The data were analyzed by correlation analysis and principal component analysis(PCA). 【Result】 Averages of TSS,SSC,sucrose,fructose,glucose,TA content,sweetness value,RST and RTT of Tainong fruit were higher than those of Guifei. The averages of single fruit mass,fruit shape index,edible rate and Vc content of Guifei fruit were higher than those of Tainong. Mango fruit of the same variety from different producing regions exhibited significant differences in TSS,SSC,sucrose,glucose,fructose,Vc content and sweetness value (P<0.05),while the difference in single fruit mass,fruit shape index,edible rate,TA content,RST and RTT was not significant(P>0.05). There were positive and negative correlations among some of the 13 quality indicators. And the total of 13 quality indicators were integrated into 4 principal components(PC1,PC2,PC3 and PC4)through PCA,and the cumulative variance contribution rate reached 85.078%,which could represent the most information of the original quality traits. Besides,the factor scores of Tainong PC1 in Ledong,Guifei PC2 in Changjiang,Guifei PC3 and PC4 in Sanya were the highest. 【Conclusion】 The fruits of Tainong and Guifei possess unique quality characteristic. The fruit of Guifei tastes sour and less sweet than Tainong. The fruit quality characteristics of Ledong Tainong,Sanya Guifei and Changjiang Guifei are better.
