The susceptibility to chilling injury and quality changes of 'Tango' mandarins stored at different temperatures was evaluated in fruit grown at two locations in Andalusia (Spain) and grafted on Carrizo Citrange or FA5 rootstock. The peel disorders were also characterized by a microstructural study.
Fruit developed chilling injuries, manifested as pitting lesions affecting the equatorial area of the fruit stored at 1 °C or 5 °C; fruit growing on FA5 rootstock showed a slightly lower incidence. The microstructural study revealed that only the upper layers of flavedo were affected in the damaged fruit, the epidermal and hypodermal tissues being dramatically collapsed. Although the fruit was prone to accumulate ethanol, especially after the shelf life that followed the different periods of cold storage, the ethanol did not compromise the overall flavor.
Storage of 'Tango' fruit was limited by chilling injuries when stored at 1 °C or 5 °C for more than 20 days. Moreover, at these temperatures, the fruit was prone to accumulate ethanol and develop off flavors. At 9° C, the fruit could be stored for 30 days without compromising external or internal quality. Growing location and rootstock influenced some quality attributes at harvest but not during storage. © 2020 Society of Chemical Industry.
评估了在西班牙安达卢西亚的两个地点种植的、嫁接到卡里佐柑橘或 FA5 砧木上的‘Tango’橘子在不同温度下贮藏时对冷害和品质变化的敏感性。还通过微观结构研究对果皮病进行了特征描述。
果实发生冷害，表现为凹陷损伤，影响在 1°C 或 5°C 贮藏的果实的赤道区域；在 FA5 砧木上生长的果实发病率略低。微观结构研究表明，受损果实仅在上皮层flavedo 受到影响，表皮和皮下组织明显塌陷。尽管果实容易积累乙醇，尤其是在不同冷藏期之后的货架期内，但乙醇并没有损害整体风味。
当‘Tango’果实在 1°C 或 5°C 下贮藏超过 20 天时，会受到冷害的限制。此外，在这些温度下，果实容易积累乙醇并产生异味。在 9°C 下，果实可以贮藏 30 天而不会影响外观和内部品质。种植地点和砧木在收获时会影响一些品质特性，但在贮藏过程中不会。© 2020 英国化学学会。
