摘要 为提升江西省特色品种马家柚果实品质,以不套袋处理为对照(CK),研究了5种纸袋类型[单层黄色纸袋(T1)、双层外黄内黑纸袋(T2)、三层外黄内黑纸袋(T3)、双层外红内黑纸袋(T4)、三层外红内黑纸袋(T5)]和4个摘袋时期[9月25日(Z1)、10月10日(Z2)、10月25日(Z3)、11月10日(Z4)]对马家柚果实外观及内在品质的影响。结果表明,使用双层或三层纸袋套袋的马家柚果实外观品质(CCI值为-0.38~-0.08)显著高于不套袋和套单层纸袋处理(CCI值为-1.69~-1.40),但不同颜色对品质的影响差异较小。套袋对马家柚的果型、可食率和果实主要内含物(总糖、可滴定酸、Vc等)含量无显著影响,而T2、T3、T4在增加主要类胡萝卜素含量方面效果更好,其中T3的果实β-胡萝卜素含量最高(22.64μg·g^(-1)),T2的番茄红素含量最高(29.06μg·g^(-1))。不同摘袋时期处理并不会显著改变马家柚原有的果型、可食率和果实主要内含物含量,但对果皮和果肉的色泽以及主要类胡萝卜素含量会产生影响,其中Z3的果实果皮色泽最佳(CCI值为26.44),且果实β-胡萝卜素(23.17μg·g^(-1))和番茄红素含量(29.14μg·g^(-1))最高,但与带袋采收(Z4)无显著差异。综合劳动力考虑,以套袋后带袋采收为佳。本研究结果为改善马家柚的果实品质提供了理论依据。 To improve fruit quality of Majia pomelo,a characteristic cultivar in Jiangxi province,the effects of 5 types of bags and 4 debagging times on fruit appearance and inner quality of Majia pomelo were explored.The five types of bags include single-layer yellow paper bag(T1),double-layer paper bag with the outside bag being yellow and the inner bag being black(T2),three-layer paper bag with the outside bag being yellow and the inner bag being black(T3),double-layer paper bag with the outside bag being red and the inner bag being black(T4),and three-layer paper bag with the outside bag being red and the inner bag being black(T5).The four debagging times were September 25(Z1),October 10(Z2),October 25(Z3),and November 10(Z4).The results showed that the fruit appearance quality of Majia pomelo bagged with two or three layers of paper bags(CCI value:-0.38 to-0.08)was significantly higher than that without bagging and single-layer paper bags(CCI value:-1.69 to-1.40),but there was little difference in the effect of different colors on quality.Bagging had no significant effect on the fruit shape,edible rate and main fruit inclutions(total sugar,titratable acid and Vc,etc)of Majia pomelo,but T2,T3,T4 had better effect on increasing the content of main carotenoid.Among them,the fruits of T3 had the highestβ-carotene content(22.64μg·g^(-1)),and the fruits of T2 had the highest lycopene content(29.06μg·g^(-1)).The experimental results of different debagging times showed that the fruit shape,edible rate and main fruit inclutions of Majia pomelo was not significantly changed,but the color of peel and flesh and the content of main carotenoid were affected.The fruits of Z3 had the best peel color(CCI value was 26.44),and the contents ofβ-carotene(23.17μg·g^(-1))and lycopene(29.14μg·g^(-1))were the highest.However,there was no significant difference with harvesting with bags.Considering the labor force,harvesting with bags after bagging was prefect.The results provided theoretical basis for improving fruit quality of Majia pomelo.
