摘要
研究了红地球和巨峰葡萄采后果实品质的变化规律。结果表明:无论在常温下还是在贮藏过程中,红地球和巨峰葡萄中还原糖、可滴定酸、VC含量逐渐减少,其中可滴定酸VC含量变化与贮藏时间呈显著的负相关;保鲜剂处理能明显降低还原糖、可滴定酸、VC的降解和损失。红地球葡萄的耐藏性明显好于巨峰葡萄,在0℃+CT-2+聚乙烯塑料包装条件下,巨峰葡萄贮至135d好果率为87.8％,而红地球葡萄贮至150d好果率仍达92.7％。
Storage quality of postharvest Red Globe and Kyoho grapes after harvest was studied. The results showed that during the storage and at the room tempreture, the content of reducing sugar, titrataboe acid, and VC decreased gradually, where as, changes of titratable acid and VC content were negatively related to the time of storage significantly. Fresh keeping agent treatment could lower the loss of reducing sugar, titratable acid and VC. Red Globe grapes had longer storage life than Kyoho obviously. Under the condition of 0℃ + CT - 2 + polyethylene film, the rate of sound fruit of Kyoho was 87.8% after 135 days storage; and that of Red Globe was 92. 7% after 150 days storage.
