中文摘要：
将砂糖橘（Citrus reticulata Blanco）果实分别置于1、3、6和9℃下贮藏，比较其贮藏效果及冷害对果实品质的影响。结果表明：砂糖橘最适贮藏温度为6℃，在1～3℃贮藏易发生冷害。冷害导致果实外观品质下降，果肉乙醛和乙醇含量累积，果肉异味，品质下降。1℃贮藏的果实呼吸速率和乙烯释放速率较6℃高，丙二醛（MDA）含量增加，丙酮酸脱羧酶（PDC）和乙醇脱氢酶（ADH）活性大幅度提高。说明在冷害温度下，砂糖橘果肉异味是由于乙醛和乙醇累积产生，而果实呼吸速率的提高与PDC和ADH活性的增加密切相关。
英文摘要：
Postharvest ＇ Shatangju＇ which results in quality reduction of pulp （Citrus reticulata Blanco） fruit are susceptible to chilling injury, However, the mechanism of quality reduction has not been well understood yet. ＇ Shatangju＇ fruit were stored at 1℃, 3 ℃, 6 ℃ and 9℃ The storage effect, pulp quality and physiological responses were compared to each other. The results indicated that chilling injury symptom occurred in the fruit stored at 1℃ or 3 ℃, and 6℃ was the optimum temperature for storage. Chilling injury not only reduced the appearance quality of the fruit, but also resulted in accumulation of aldehyde and ethanol, and led to unpleasant favor and quality reduction in pulp. Compared with the fruit stored at 6℃, the respiratory rate, ethylene production, the content of malondialdehyde （ MDA）, the activities of pyruvate decarboxylase （PDC） and alcohol dehydrogenase （ADH） increased dramatically in the fruit stored at 1℃. It was suggested that, during c temperature storage, the quality reduction of pulp was due to the accumulation of aldehyde and ethanol, and the increase of respiratory rate may be due to the increase of PDC and ADH activities.
