摘要/Abstract

摘要： 研究不同冷藏温度对蜜脆苹果贮藏期生理生化及货架期品质保持的影响，为蜜脆苹果冷藏方式的改进提供理论依据和实践指导。设置不同冷藏温度0℃和3℃，定期测定贮藏期间的各项生理生化指标和货架期品质指标，并在贮藏末期观察统计主要生理病害的病情指数。3℃冷藏与0℃相比，能较好的抑制蜜脆苹果冷藏期间可滴定酸含量的下降，保持果实色泽，推迟呼吸、乙烯高峰的出现，抑制冷害的发生，具有较高的超氧化物歧化酶（superoxide dismutase，SOD）、过氧化物酶（peroxidase，POD）和过氧化氢酶（catalase，CAT）活性，并能延缓货架期品质的下降，表现出较好的贮藏效果。各项测定指标表明，多数苹果品种适宜贮藏的0℃对蜜脆苹果来说并不适合，3℃更适合蜜脆的冷藏。

Abstract: The effect of different cool storage temperatures on postharvest physiology and shelf quality of ‘Honeycrisp’ apples has been studied. Further theoretical basis for the development and application of cool storage technique of ‘Honeycrisp’ apples is to be provided. This research was carried out at temperatures of 0 and 3℃. Physiological indicators were measured regularly during storage and shelf life and physiological diseases index was counted in the end. The results indicated that compared with 0℃, storage temperature at 3℃ could inhibit the decrease in titratable acid content, keep color and lustre of pericarp, delay the time of respiration and ethylene peak, control the incidence of chilling injury and had higher SOD, POD and CAT activity. Furthermore, the shelf-life quality of ‘Honeycrisp’ apples stored at 3℃ was better. The experiment proved that 0℃ appropriate to most apple varieties was not suitable for ‘Honeycrisp’ cool storage, while 3℃ was better.
