摘要 系统分析了串枝红杏果实生长动态及发育过程中维生素C、有机酸、可溶性糖的变化规律。结果表明:串枝红杏果实的生长发育动态呈"快-慢-快-慢"的"双S"型曲线。整个发育期大致可分为4个时期:果实第1次迅速生长期,果实第1次缓慢生长期,果实第2次迅速生长期和果实成熟前缓慢生长期。果实第一次缓慢生长期与果实硬核期相吻合,果实第1、2次迅速生长期是果实增长的2个关键时期。果实纵、横、侧径与果实鲜重、体积的变化曲线十分相似,具有同步增长的趋势。维生素C含量在果实发育初期和成熟期较高,硬核期降低;有机酸含量的变化趋势以果实发育初期较高,硬核期降低,之后又有一次小高峰,成熟时降至最低;可溶性糖含量随果实的生长而增加。 This paper studied the growth curve and content variation of Vitamine C, organic acid and soluble sugar, which in the Chuanzhihong apricot fruit during the process of fruit development. The results showed that the growth and development of Chuanzhihong apricot fruit was double S-shaped curves: fast-slow-fast-slow. The whole growth and development course was divided into four periods: the first fast growth period of fruit, the first slow growth period of fruit, the second fast growth period of fruit and the second slow growth period of fruit at the beginning of ripening. The first slow growth period of fruit inosculated with the hardening of the core, and the first and the second fast growth period of fruit were two pivotal for fruit to grow. The variational curves of fresh fruit weight and fruit volume were almost semblable with that of vertical diameter, horizontal diameter and side diameter. They had the synchronous rising tendency. Vitamine C content was higher in young fruit and maturation, lower in the core hardening stage of fruit; the content of organic acid of apricot at the stage Ⅱ was highest and than fell down to the lowest at mature stage; the total content of soluble sugar increased gradually with the fruit maturing.
