锦绣黄桃优变株系果实贮藏保鲜性能比较试验

在常温（28～35℃）与（5±1）℃低温条件下,对硕锦1号、硕锦2号、硕锦3号等3个锦绣黄桃优良变异株系的贮藏果实品质变化与保鲜性能进行研究。结果表明,在常温条件下,3个优变株系的果实可溶性固形物、可滴定酸、总糖含量及果实硬度、好果率、果实保水率均随着贮藏时间的延长而降低,贮藏保鲜性能均略差于锦绣黄桃,贮藏期均以不超过6d为宜;在低温条件下,3个优变株系的各项贮藏保鲜性能指标变化趋势和表现与常温下相近,贮藏期均以不超过16d为宜。

Comparision Experiment on Fruit Storage Properties of Superior Variant Strains of 'Jinxiu' Yellow Peach

Under normal atmospheric temperature（28～35℃）and（5±1℃）low temperature conditions,change in storage quality and storage properties of three good variant strains of ＇Jinxiu＇ yellow peach,as follow ＇Shuo Jin 1＇,＇Shuo Jin 2＇and ＇Shuo Jin 3＇ was studied.The results showed that the trends in storage quality and storage properties of the three good variant strains in normal atmospheric temperature were similar to those in low temperature,i.e.the soluble solids,titratable acid,total sugar content,fruit firmness,good fruit rate,and water-retention rate of three good variant strains all reduced with the extension of storage time,as well as the storage properties were worse than ＇Jinxiu＇ yellow peach.The author considered that it was suitable that the storage period was less than 6 days and 16 days in normal and low termpature resperctively.
