摘要
对无患子果实生长发育动态及果肉内含物含量变化进行研究,结果表明,无患子果实纵径、横径、侧径、鲜质量等性状发育进程呈现明显的S型生长曲线特征;以果实生长发育时期为横轴(x),分别以果实纵径、横径、侧径、鲜质量的均值为纵轴(y),构建的果实生长发育数学模型表明,无患子果实生长各性状与果实发育时期高度相关,数学模型可以正确地反映无患子果实生长发育动态变化规律。对无患子果实脱落规律、果肉含水量、可溶性糖含量、皂苷含量变化规律等综合分析表明,10月下旬,无患子果实发育成熟,生长性状趋于稳定,果肉含水量和可溶性糖含量从峰值下降至相对较低水平,而果肉皂苷含量相对较高,因此提出该时期为无患子果实采摘的适宜时期。
The dynamic changes of fruit development and pulp inclusion of Sapindus mukorossi were studied. The results showed that the development process of fruit vertical diameter, transverse diameter, side diameter and fresh weight presented an obvious Sigmoid growth curve. The mathematical models of fruit growth and development were built by using development period as X-axis, and using respective mean of fruit traits as Y-axis. Meanwhile, the models were proved available to reflect the change rule, because the fruit growth traits highly correlated with devel- opment periods. The change rules of fruit drop, pulp water content, pulp soluble sugar content and pulp saponin content were analyzed comprehensively. The resuh indicated that the fruits matured and the growth traits tended to- wards stability in later October, and the pulp water content and soluble sugar content decreased from peak to rela- tively low levels. However, the pulp saponin content was relatively high at the same time. So the suitable period for fruit harvest of S. mukorossi was in later October.
