In this research the effects of postharvest 1–Methylcyclopropane (1–MCP) treatments on quality during storage were carried out. For this purpose, 1–MCP treatments were materialized on pear fruits harvested from Çanakkale Biga region with 312,5 ppb, 625 ppb and 1.250 ppb doses respectively. Fruit of different treatments were stored between 2°C and 3°C storage temperature and 85%–90% relative humidity conditions for 60, 120 and 180 days respectively. Fruit were kept between 20°C and 22°C temperature and 50%–60% relative humidity conditions for 7 days as shelf life after each storage period. Some quality parameters such as fruit firmness, soluble solids content, titratable acidity, skin color development, ethylene production, total phenolics compound and fungal decay incidence were assessed after harvest and each storage and shelf life periods. According to the results, quality losses increased with prolonging the storage period. Besides 625 ppb and 1.250 ppb treatment doses were found as the most effective on keeping the quality during storage and shelf life. However any significant effects of 312.5 ppb treatment dose can be determined on quality parameters.
