采用6个栽培地点-季节组合，研究了桃果组成与生长的关系。测定了单个果实的生长和糖、酸含量。该方法结合了增长的功能描述和相关分析。果实生长分为两个阶段：果核生长和果肉生长的第一阶段，果肉生长的第二阶段。分析了果肉中蔗糖、还原糖、苹果酸和柠檬酸的浓度。各组合内生长和组成的变异性较大。虽然疏伐时直径最大的果实往往是柠檬酸浓度最高的果实，但其组成的变化主要与第二阶段的生长变化有关。第二阶段密集生长的果实蔗糖和苹果酸浓度最高，还原糖和柠檬酸浓度最低。讨论了这些结果的生理意义。
The relationship between peach fruit (Prunus persica L. Batsch) composition and growth was studied in six cultivar-training-site-season combinations. Individual fruit growth and sugar and acid content were measured. The approach combined a functional description of growth and a correlation analysis. Fruit growth was divided into two phases: pit growth with the first stage of the flesh growth, and a second stage of flesh growth. Fruit composition was analysed for the concentrations of sucrose, reducing sugars, malic and citric acids in the flesh. The variability of growth and composition within each combination was high. The variation of composition was mainly related to the variation of growth during the second phase, although the fruit having largest diameters at thinning were often those with the highest citric acid concentration. Fruits growing intensively during the second phase had the highest sucrose and malic acid concentration and the lowest reducing sugar and citric acid concentration. The physiological significance of these results is discussed.
