ABSTRACT This study aimed to understand the involvement of agro-climatic conditions, external quality and defence system of Hass avocado fruits on blackspot disorder development after prolonged cold storage. The results prompt us to conclude that the weight of the fruits at harvest and weight loss during the storage period is involved in blackspot disorder development. Large incidence of lenticelosis in fruits and lower activity of SOD, CAT, POD, PAL, phenolics and epicatechin levels may contribute to blackspot spot development during cold storage. Non-supervised techniques pointed for epicatechin and derivatives, temperature, relative humidity and enzymes as important specific variables that affect blackspot disorder while predictive models showed positive correlation with minimum temperature (below 5°C) and maximum temperature and relative humidity displayed negative association with blackspot.

与储存的哈斯鳄梨（Persea americana Mill）水果中的“黑点”障碍相关的解开因素

摘要 本研究旨在了解哈斯鳄梨果实的农业气候条件、外在品质和防御系统对长期冷藏后黑斑病发展的影响。结果提示我们得出结论，收获时果实的重量和贮藏期间的重量损失与黑斑病的发展有关。水果皮孔病发病率高，SOD、CAT、POD、PAL、酚类和表儿茶素水平较低，可能导致冷藏期间黑斑的形成。非监督技术针对表儿茶素及其衍生物、温度、
