| 摘 要： | 通过对桃果实发育过程中维生素C、可溶性糖、有机酸、游离氨基酸及蛋白质含量的测定,系统分析了它们在整个生长发育过程中的动态变化。维生素C含量呈V形的变化曲线,幼果和成熟时较高,其它时期较低;可溶性糖总量随果实的生长而增加,但还原糖与非还原糖含量的变化趋势恰好相反;有机酸、游离氨基酸和蛋白质三者含量都是幼果时较高,成熟时最低。各种营养成分的变化虽然有所不同,但与果实的相对生长速度及花后天数有明显的相关关系。另外,对果实生长发育过程中营养成分的系统分析方法也进行了研究。

| Abstract: | The changes of vitamin C,soluble sugar,organic acid,free amino acid and protein con-tents were studied in peach fruit during its maturation. The results were as follows ;The change of vitamin C content showed a "V"-shape curve.it was higher in young fruit and maturation,lower in other periods;the total content of soluble sugar increased gradually with the fruit maturing,but the reducing sugar and non-reducing sugar content showed evidently different trends of changes ; the content of organic acid,free amino acid and protein were highest in young fruit ,after that,they decreased gradually and reached lowest when the fruit matures. All of the nutritional components had different trends of change,but they had obviously negative correlations with the growth speed and the days of bloom. In addition,the systematic analytical method of main nutritional components in fruit maturation was also studied. |
