In this research, ethephon, was applied to reduce fruit removal force, and increase percentage of harvested fruit. The objective of this study was investigate the effect of preharvest ethephon application on fruit quality of sour cherry during storage period at modified atmosphere packaging (MAP) and 0°C temperature. Modified atmosphere packaging was used with 10, 15 and 75 percent for O2, CO2 and N2 respectively. This composition of gas with holding at 0°C caused increscent the postharvest shelf life of fruit. Fruit samples were evaluated at harvest date and after 6 weeks holding in storage. Weight loss, skin colour, pH, total soluble solids (TSS), titrateable acidity (TA), TSSrr A ratio, firmness of fruits were monitored. Ethephon concentration influenced on increasing total soluble solid, TSSrr A ratio and L* value and decreasing titrateable acidity at harvest date, Fruit colour became dark after 6 weeks holding in storage.
