摘要
以拉萨地区‘新红星’苹果未套袋果实和套袋果实为试材,分别采用室温和室温气调袋2种贮藏方式,研究采前套袋及采后气调袋贮藏对‘新红星’苹果果实质地及生理特性的影响。采收时分别测定果形指数、单果质量、果实密度及色差等指标,并测定贮藏过程中果实硬度、可溶性固形物(TSS)、可滴定酸和维生素C质量分数。结果表明,果实套袋后单果质量增加,果实密度减小,硬度、可溶性固形物、可滴定酸质量分数、维生素C质量分数等明显降低,同时色泽变艳;气调袋贮藏的果实硬度、可溶性固形物、可滴定酸质量分数、维生素C质量分数下降缓慢,且未套袋果实略高于套袋果实。采前套袋果实综合品质较佳,气调袋贮藏能够延缓果实衰老进程,尤其是对采前套袋果实。
In this paper,Lhasa ＇Starkrimson Delicious＇ apple under the treatment of pre-harvest bag- ging and no preharvest bagging were used as material, storage under room temperature with and with- out modified-atmosphere package. The effect of pre-harvest bagging and modified-atmosphere package storage on fruit texture and physiological characteristics of Lhasa ＇Starkrimson Delicious＇ apple were discussed. The fruit shape index, fruit mass, fruit density and fruit color differences after harvest, and the indexes of fruit hardness, total soluble solids（TSS）, titratable acid and vitamin C mass fraction during the process of storage were examined. The results showed that the fruit mass increased by pre- harvest bagging, while the fruit density, fruit firmness, TSS mass fraction, titratable acid mass fraction and vitamin C mass fraction decreased. The fruit with pre-harvest bagging had bright color. The modi- fied-atmosphere package could delay the decline of fruit hardness, TSS, titratable acid and vitamin C mass fraction were higher than that of the bagged fruit under the treatment of without pre-harvest bagging. The fruit with pre-harvest bagging showed better quality than un-bagged fruit,and the modi- fied-atmosphere package storage could prolong the fruit shelf-life, especially the fruit under pre-har- vest bagging treatment.
