Postharvest, 1-MCP was applied to Granny Smith apple fruits at 10 °C and 24 hours at doses of 0, 156.25, 312.5, 625 ppb. The 1-Methylcyclopropene (1-MCP) product used as a reference in the study was applied at a dose of 625 ppb. After the applications, the fruits were stored at 0±0.5 °C temperature and 90±5% relative humidity conditions for 4 months and quality analyzes were made every month. For the shelf life study, the fruits were kept for 1 week at 20 °C temperature and 55±5% relative humidity in each period, and quality analyzes were made. In each analysis period, the weight loss, fruit color, fruit texture, soluble solid content (SSC), titratable acidity (TEA), respiration rate, ethylene production amount analyzes and scald formation observations were made. As a result of the study, it was observed that 156.25 and 312.5 ppb 1-MCP applications and reference product application were effective in suppressing ethylene production, preventing the formation of scald, fruit flesh firmness, h0 value, and TEA preservation.
