Abstract:

【Objective】 Fruit of Amygdalus ferganensis var nectarina has good quality and good taste, and its distribution area in southern Xinjiang is seriously restricted due to its poor storage and transportation,so it is of great significance to study the storage methods of A.ferganensis var nectarina fruit in order to extend the shelf life of peach.【Methods】 Four excellent germplasm of A.ferganensis var nectarina (Lvguang 5, 13-6#,Lvguang 6 and Huangguang 1) in Aksu region were selected as the research objects. The dynamic changes of respiration metabolism index (respiration intensity, gas ratio change, ethylene release) and texture index (hardness, elasticity, chewiness, stickiness) of A.ferganensis var nectarina fruits during storage were determined by MA cold storage and (1 ± 1)℃ cold storage.【Results】 The results showed that A. ferganensis var nectarina fruit was a typical respiratory climacteric fruit, with obvious respiration and ethylene release peaks. On the 15th day of cold storage treatment, the four nectarines reached the highest value, 13-6# was the highest 37.74 mgCO2/(kg·h), and lvguang 6 was the lowest 28.39 mgCO2/(kg·h). MA refrigeration treatment reached the highest value only after 35 days of cold storage treatment, and the highest value of Huangguang 1 was 32.40 mgCO2/(kg·h), and the lowest value of lvguang 6 was 25.17 mgCO2/(kg·h). MA refrigeration treatment can effectively inhibit the release of ethylene. The ethylene release of refrigeration treatment has an obvious peak at the 15th day, and the peak range is 10.92-17.64 μL/(kg·h), the peak value of MA refrigeration treatment was obvious in the 20th-30th day, ranging from 18.47-24.23 μL/(kg·h)。The microenvironment of low temperature, low O2 and high CO2 effectively inhibited the reduction of hardness, stickiness, cohesion and chewability, so as to better inhibit fruit decay. 【Conclusion】 The fruit decay time of MA cold storage is about 15 days later than that of cold storage, the maturity of Lvguang 6 is obviously delayed during storage, and the fruit texture of Lvguang 6 is better than that of the other three germplasms.

摘要：

【目的】研究新疆油桃果实不同贮藏方式对其呼吸代谢和质构指标的影响,为延长桃果的商品货架期提供参考。【方法】以阿克苏地区4个新疆油桃优良种质绿光5号、13-6#、绿光6号、黄光1号为研究对象,设置(1±1)℃ MA冷藏和(1±1)℃冷藏两种方式,测定贮藏期间新疆油桃果实的呼吸代谢指标(果实呼吸强度、气体比率变化、乙烯释放量)和质构指标(硬度、弹性、咀嚼性、胶黏性)的动态变化。【结果】新疆油桃果实是典型的呼吸跃变型果实,具有明显的呼吸及乙烯释放高峰;MA冷藏处理较冷藏方式更能有效抑制4种新疆油桃果实的呼吸速率,推迟呼吸高峰的出现;冷藏处理到第15 d时4种油桃均达最高值,13-6#最高为37.74 mgCO2/(kg·h),绿光6号最低为28.39 mgCO2/(kg·h);MA冷藏处理到第35 d时才达最高值,黄光1号最高为32.40 mgCO2/(kg·h),绿光6号最低为25.17 mgCO2/(kg·h)。MA冷藏处理能有效抑制乙烯的释放,冷藏处理的乙烯释放量出现明显峰值在第15 d,高峰范围在10.92~17.64 μL/(kg·h),MA冷藏处理的出现明显峰值在第20~30 d,范围在18.47~24.23 μL/(kg·h)。低温、低O2、高CO2的微环境有效抑制了硬度、胶黏性、内聚性、咀嚼性的降低,从而更好地抑制果实腐烂。【结论】MA冷藏方式较冷藏方式延缓果实腐烂时间15 d左右,贮藏期间绿光6号的成熟度明显有所延缓,果实质地优于其它3个种质。
