摘要:

目的:比较不同肉质和成熟度的桃品种常温条件下的贮藏特性。方法:以软溶质型桃‘霞晖1号’、硬溶质型桃‘霞晖6号’、不溶质型桃‘金晖’为试材,研究7、8 成熟度条件下果实常温贮藏过程中果实硬度、乙烯释放量、可溶性固形物、可溶性糖和有机酸含量的变化。结果:货架期间,所有处理桃果实均有正常乙烯释放峰值出现,不溶质桃果实具有最长的果实货架生理周期,但可溶性固形物和可溶性糖含量较软溶质和硬溶质品种低,风味不足,‘霞晖6号’8 成熟果实在贮藏过程中,能保持较高的可溶性固形物和可溶性糖含量,风味渐佳。结论:硬溶质肉质类型桃在货架期间贮藏效果较好,8 成熟是其适宜的采收成熟度。

Abstract:

Objective: To compare the storage characteristics of different peach flesh types at different degrees of maturity.
Methods: Peaches of three cultivars ‘Xiahui 1’ soft-melting, ‘Xiahui 6’ hard-melting and non-melting ‘Jinhui’, harvested
at two different degrees of maturity (70% and 80%), were analyzed for changes in flesh firmness, ethylene production,
soluble solid content, soluble sugars and organic acids. Results: Peach fruits of all the three cultivars had the normal ethylene
release peaks. The non-melting peaches possessed the longest shelf-life, accompanied with lower soluble solid and soluble
sugar content, compared to the soft-melting and hard-melting cultivars. However, ‘Xiahui 6’ fruits at 80% maturity stage
maintained higher amounts of soluble solid and soluble sugar and had better flavor during storage. Conclusion: The hardmelting
peaches maintain better quality during shelf-life storage, and the optimal harvest time is at 80% maturity stage.
