This study aimed to investigate quality changes in Valencia Late oranges grown in Dörtyol and Samandag regions during storage. Valencia Late orange fruits were harvested from trees grafted on sour orange rootstock and planted 7 x 7 m and kept at 4 and 6oC and 85-90% relative humidity for 6 months. Changes in weight loss, incidence of fungal and physiological disorders, total soluble solids, juice and juice pH, titratable acidity, green bottom, skin colour L* and hue values were determined during storage at a 30-day interval. According to data, Valencia Late oranges stored better at 4oC. Valencia Late oranges grown in Dörtyol region could be kept at 4oC and 85-90% relative humidity for 4 months and at 6oC and 85-90% RH for 3 months.
