The effect of different harvesting dates on the quality and storage ability was studied for fruit of Coscia pear cultivar, which planted in the area of Daher Aljabal- Sweida during two successive seasons 2007-2008. Fruit were harvested in three different dates by week time intervals and stored for seven months at (0-1 Cº and 90-95 % RH) in the storage units of apples and vine research department. The effect of harvesting dates of fruit on the physical and chemical properties was determined during period of 7 months in cold storage, by month time intervals. The second date of harvest affected by decreasing weight loss percentage, decay percentage, titratable acidity T. A, starch content and firmness, in addition to that total soluble Solids T. S. S, number of acidity PH, storage ability and shelf life were increased compared to the harvested fruit in the different dates.
