| 摘 要： | 分析测定了大石早生、龙园秋李、黑宝石、安哥诺4个李品种的果实生长动态,及其主要糖、酸、维生素C含量的变化规律。结果表明,李果实发育过程中主要糖的变化规律基本一致,即其发育早期,几乎没有蔗糖的积累,果糖含量也较低,而葡萄糖含量相对较高;随着果实的发育,果糖含量持续增加,葡萄糖含量增长缓慢,发育后期蔗糖显著积累。但不同品种含糖量差异较大,龙园秋李总糖含量最高,安哥诺次之,黑宝石和大石早生较低。不同李品种的各类糖含量不同大石早生、龙园秋李蔗糖含量最高,果糖次之,而葡萄糖含量极低;黑宝石以葡萄糖和蔗糖为主,果糖含量相对较低;安哥诺则以果糖和葡萄糖为主。果酸和维生素C含量则随果实发育呈逐渐下降的趋势。 |

| Abstract: | Four plum cultivars, including ?ぉぉぃしゎせ, Longyuanqiuli, Fraiar, Angeleno, were used to investigate the changes of the dynamic pattern and contents of main sugar, acid and vitamin C. The 4 cultivars' main sugar contents changed consistently. There were little sucrose and fructose in pulp at the early development stage, whereas glucose content was relatively high. During fruit development, fructose content increased all the time, glucose content increased slowly,sucrose content extended largely at the ripening stage. Furthermore, different sugar contents were in the highest fluctuation in various plum cultivars. Sucrose was dominant in Dashizaosheng and Longyuanqiuli. Glucose and sucrose were dominant in Fraiar. Fructose and glucose existed mostly in Angelino. The contents of acid and vitamin C decreased along with plum fruit development. |
