不同除袋时期对红芒6号芒果果实品质的影响

研究不同除袋时期对红芒6号芒果果实外观、果皮色素、果皮色泽、果实内在品质的影响.结果表明:随着除袋时间的推迟,果实着色面积减少.早除袋处理的果皮色素含量显著高于晚除袋处理,果皮色泽如果皮亮度以晚除袋处理高于早除袋处理,但色相角度相反:果实内在品质如维生素C、可溶性同形物以采前10～15天最佳.红芒6号芒果在金沙江干热河谷地带的最佳除袋时期为采前10～15天,除袋后,果皮花青苷含量迅速上升,果实着色最快,果面光洁,外观最佳.

Effect of Different Debagging Stages on Fruit Quality of Mango Cultivar'Zill'

Fruit of mango cultivar 'Zill'(Mangifera indica Linn.'Zill') were debagged at different stages to observe their appearance, pericarp pigment, pericarp color and internal quality. The results indicated that the colored area of the pericarp was reduced with the delay in debagging. The mango fruit debagged earlier contained significantly higher pigment in pericarp than that debagged late. Brightness of the pericarp of the fruit debagged late was obviously higher than that of the fruit debagged earlier, whereas the hue angle was just the opposite. The fruits debagged were the highest in fruit internal quality such as the contents of vitamin C and soluble solids. In Jinshajiang valley, Yunnan Province, the most appropriate debagging stage for 'Zill' mango is 10～15 days before harvest. After debagging, anthocyanin content of the pericarp increased rapidly, the red colour developed fastest in the pericarp, the surface of the pericarp turned bright and clean, and the fruit looked the best in appearance.
