中文摘要：

以贵州麻江规模种植的“园蓝”、“芭尔德温”、“粉蓝”、‘锑芙蓝”、“灿烂”5个晚熟蓝莓品种为研究对象试材，在自发气调包装结合冰温（-1±0．3℃）贮藏条件下考察各5个品种在贮藏期间（75d）的呼吸强度、乙烯释放速率、腐烂率、失重率、色差、可溶性固形物、总酸、花色苷和总酚的变化，探讨5个品种间果实的品质变化差异。结果表明：贮藏期内，5个品种蓝莓的可溶性固形物、总酚和花色苷含量均呈先上升，后下降趋势；总酸波动不大；腐烂率、失重率、乙醇含量和色差则呈现不同程度的上升趋势。“梯芙蓝”水份含量最高，在整个贮藏过程中呼吸强度处于最高水平、可溶性固形物含量下降辏陕，腐烂率最高。“园蓝”可溶性固形物和花色苷含量一直处于最高水平；“粉蓝”腐烂率最低。5个品种的耐贮性为：粉蓝〉灿烂〉芭尔德温〉园蓝〉梯芙蓝。

英文摘要：

In the present study, the respiration rate, ethylene production rate, rot rate, weight loss rate, color difference, soluble solid, total acid, total alcohol, total phenols and anthocyanin content of five different late-maturing blueberry varieties （Gardenblue, Baldwin, Powderblue, Tifblue and Brightwell） from Majiang （Guizhou） were determined, which were stored under 14-0.3 ℃ for 75 days. And then the changes of storage quality were compared and analyzed. The result showed that the soluble solids, total phenols and anthocyanin content of five kinds of blueberry declined in the earlier days then rose with prolonging storage time. No obvious fluctuation was observed in total acid. The rot rate, weight loss rate and colour difference showed a rising trend. Among them, Tifblue showed the highest rot rate because of high respiration rate, water content, and soluble solid decline tendency; anthocyanin content of Gardenblue kept the highest level; the rot rate of Powderblue was the lowest. The sequence of storability was as follows： Powderblue〉Brightwell〉 Baldwin〉 Gardenblue〉 Tifblue.
