To earn more money from the apricot fruit marketing, consideration of harvesting time and packing method is important. This research was done to determine the best harvesting time and packing method of apricot fruit. Fruits of 'Derakhshan' and 'Sahand 97' cultivars with the commercial cultivar 'Ordoubad 90' (as control), were harvested in three stages of ripening based on the fruit’s skin color index. The first harvest was occurred when fruit’s skin had a predominantly green background with yellowish tinges, second and third harvests were coincided with yellow background with green tinges and yellow-orange background color of fruits. Fruits were packed with polyethylene cover or without it, and were stored at +2 ˚C and 85% RH for 0 (control), 7, 14, 21 and 28 days. Fruit weight, fruit firmness, total soluble solids, pH and electrical conductivity of fruit extract were measured. Optimum harvest time was according to yellow background with green tinges of fruit’s skin and polyethylene packaging prolonged its storage life. Fruits of 'Derakhshan' and 'Ordoubad 90' could be cold-stored with suitable quality for 14 and 28 days, respectively. 'Sahand 97' had a notable storage life and did not show significant differences in harvesting time and packaging method at least for 28 days after storage. By delaying in harvest, shriveling, gel breakdown and decay of fruits increased considerably. Also, fruit firmness reduced and total soluble solids, pH and electrical conductivity of fruit extract raised up remarkably. Apricot fruit harvesting at the right stage with obtimized packaging increases its storage period.
