摘要: 研究了不同温度下‘大石早生’和‘紫琥珀’两个李品种果实采后色素形成及相关指标的变化。结果表明, 两个李品种采后果面颜色变化与温度密切有关。果实处于0℃下, 花色素苷含量增加缓慢,20℃下增加迅速。大石早生果皮中花青苷- 3 - 葡萄糖苷含量在采后10 d中一直呈增加趋势, 花青苷- 3 -芸香糖苷含量在前6 d增加迅速, 8 d达高峰, 而后下降。紫琥珀果皮中以花青苷- 3 - 葡萄糖苷为主, 在20℃条件下4~8 d为迅速增加期, 8 d后略下降, 而花青苷- 3 - 芸香糖苷含量低且变幅小。在0℃时, 果肉中糖、酸及pH值变化不大; 而20℃下果肉中酸含量明显下降, pH值上升, 总糖含量明显下降。这些变化与花青苷合成有一定关系。

Abstract: The paper describes the effects of different temperatures on anthocyanin synthesis and physiological changes in postharvest fruit of Prunus salicina Lindl. ‘Dashi Zaosheng’and ‘Black Ambar’. The results showed that anthocyanin synthesis of postharvest plum fruitwas closely correlated with temperature. At
0℃, anthocyanin synthesis slowly increased as compared to rap id increase at 20℃. Cyanin-3-glucoside content increased within 10 days while yanin-3-rutinside decreased at 8th day in Dashi Zaosheng peels. Both anthocyanins increased within 8 days, especially cyanin-3-glucoside, but decreased after eight days in Black Ambar peels at 20℃. No significance was observed in sugar and malic acid contents and pH changes at 0℃.However, at 20℃, malic acid and sugars contents especially fructose and sorbitol were significantly decreased as compared to increasing of pH. Those changes were related to anthocyanin synthesis.
