Post-harvest behaviour of ‘Ortanique’ (‘Topaz’) tangor citrus fruit during long-term storage at various temperatures

Cultivar ‘Ortanique’ tangor citrus fruit stored for 3 months at temperatures between 5 and 11°C kept their marketable qualities, and even improved in colour, taste and ease of peeling. Storage at 13°C led to fast deterioration and storage at 2°C caused chilling injury. Warming the fruits to 13°C for 7 days every 3 weeks during storage at 2°C prevented chilling injury and eliminated rot development. Waxing the fruits before storage had no effect on quality after storage. Generally, post-harvest changes occurring in ‘Topaz’ were very slight under most conditions examined.
