摘　　要：对中华寿桃以室温贮藏做对照,研究3种贮藏条件下桃果实的生理生化指标变化和保鲜效果。结果表明,中华寿桃保鲜效果以升温贮藏即贮藏前以30℃热空气处理48小时,再0.5±1℃下贮藏效果为好,低温伤害率仅1.67%,果实商品率高,达96.7%。变温贮藏即0.5±1℃冷藏7天,升至18℃保持48小时,重复此变温处理过程4次的效果次之;恒温贮藏即4℃预冷24小时,再0.5±1℃恒温贮藏35天后不能保证食用品质;室温贮藏的效果佳;中华寿桃以贮藏时间不宜超过35天。The physiological and biochemical changes and fresh-keeping effects of three storage conditions on Zhonghuashoutao were studied.The results showed that the best fresh-keeping effect of Zhonghuashoutao was warming storage,which was treated with hot air at 30℃for 48 hours before storage,and then stored at 0.5±1℃.Low temperature injury rate was only 1.67%,and the commodity rate of fruit was 96.7%.The effects of changing temperature treatment was the second,which was stored at 0.5±1℃for seven days,then rose to 18℃for 48 hours,and then repeated this process four times.The effects of constant temperature storage was precooling for 24 hours at 4℃and then stored for 35 days at 0.5±1℃,but the edible quality could not be guaranteed.The room temperature storage was more cost-effective.The safe shelf life of Zhonghuashoutao was 35 days.
