Abstract :The objective of this study was to determine storage and shelf life periods of Perfect Delight nectarines grown in Mersin insert ignore into journalissuearticles values(Yenice, Tarsus);. The fruit was kept at 0 °C and 85%-90% relative humidity for 8 weeks. After removal from cold storage at weekly intervals, the fruit was kept at 20 °C and 65%-70% relative humidity for 2, 4 or 6 days to determine shelf life in 3 replicates. Changes in weight loss insert ignore into journalissuearticles values(%);, fruit skin color and flesh color insert ignore into journalissuearticles values(L*, a*, b*);, fruit flesh firmness insert ignore into journalissuearticles values(N);, total soluble solids insert ignore into journalissuearticles values(%);, titratable acidity insert ignore into journalissuearticles values(g malic acid / 100 ml fruit juice);, incidence of chilling injury and fungal decay were monitored weekly during cold storage and during the subsequent shelf life at 2-day intervals. The fruit lost 4%-6% of its initial weight after 8 weeks of cold storage and showed no visible symptoms of shriveling. Fruit flesh firmness decreased, but remained at about 20 N at the end of 8 weeks of storage. Perfect Delight nectarines can be kept at 0 °C and 85-90% relative humidity for 4-6 weeks and can have a 2-day shelf life following cold storage.
