中文摘要：

以中华寿桃果实为试材,在（1±0.5）℃、相对湿度（90±5）%条件下对4个不同成熟度果实贮藏7周,通过对果实硬度、可溶性固形物、可滴定酸、乙烯生成速率、呼吸速率、细胞膜透性、褐变度等生理指标研究和果实感官品质评价,以确定适于低温冷藏的中华寿桃最佳采收期。结果表明：不同采收期对果实硬度、可溶性固形物含量和可滴定酸的保持,呼吸速率、乙烯释放及果实褐变度等方面的影响具有明显的差异,10月25日采收的果实贮藏效果明显优于其它处理。贮藏后期果实品质感官评价结果表明,低温冷藏条件下不同采收期对中华寿桃果实品质的影响依次是10月25日〉10月20日〉10月30日〉10月15日。

英文摘要：

Taking Prunus persica ＇Zhonghuashoutao＇ fruits as material,peach fruits were harvested with four different maturity degrees and stored for 7 weeks.It was performed to investigate the postharvest changes in firmness,soluble solids content,titratable acid,respiration rate,ethylene production,cell membrance permeability,degree of fruit browning and sensory quality so as to find the best harvesting dates suiting to be stored at low temperature（1±0.5）℃,RH（90±5）%.The results showed that the effects of storage harvesting on October 25 obviously was superior to the others at firmness,soluble solids content etc.At the same time applying sensory evaluation in fruit quality later storage period proved that the effects of different harvesting dates on ＇Zhonghuashoutao＇ peach fruit during storage were October 25th,October 20th,October 30thand October 15th according to its priority.
