以‘巴西’、‘威廉斯(8818)’、‘矮化威廉斯(8818-1)’3个香蕉品种的果实为试验材料,进行果实发育过程中糖、淀粉、单宁以及Vc含量的分析.结果表明,香蕉不同品种果实生长趋势及糖、淀粉、单宁和Vc的变化趋势基本一致,同一品种糖与淀粉的变化趋势正好相反.香蕉果实在整个发育过程中,以积累淀粉为主,糖含量保持较低水平(1.5％左右)；后熟期,淀粉转化为糖.香蕉果实发育过程中单宁和Vc含量均呈下降趋势.%The contents of main sugars, starch, tannins and vitamin C were analyzed during the fruit development of three banana cultivars, including 'Brazil', 'Williams (8818)'and 'Dwarf Williams(8818-1)'. The results showed that the fruit growth trends of different banana varieties were basically the same as the changes of contents of sugars, starch, tannins and Vc. The contents of sugars and starch in the same variety had an opposite trend. Starch was the main accumulated while sugars content remained low (1.5% )during the entire banana fruit development process. After -ripening period, the starch would degraded into sugars. Vc and tannins content decreased during fruit development.
