An experiment was carried out in pear orcharda (Pyrus communis) in Karaj region, to find a method to reduce post-harvest losses of ‘Shamiveh’ pears during the cold storage period, as well as by dipping the fruit in 2% and 4% solutions of calcium chloride. The first harvest time was done when fruit firmness was about 8 kg/cm2 and the skin was still green. The second harvest was done one week later. The fruit were then dipped in solutions of 2% and 4% calcium chloride after harvest and before being stored in cold 5 0C and 85% relative humidity for 60 days. The results indicated that the time of harvest had a significant effect on fruit firmness, color, total sugar, TSS, pH and taste indexes and marketability, while calcium treatments affected some indexed such as firmness, TSS and color but at on others, e.g. taste , marketability. The weight loss during the whole period of storage was only affected by the time of harvest (P= 0.01), but the amount of calcium absorption in fruit tissue was affected by calcium treatments (P=0.01). the treatment interactions indicated that there were significant effects on fruit firmness, pH, color skin and TSS and there were not any significant effects on other investigated characteristics.
