Apples cv. Granny Smith were harvested at mature stage, and treatments with 325 and 650 ppb of 1-methylcyclopropene (1-MCP) and 1800 and 1000 mg l-1 of diphenylamine (DPA) were done to investigate the effects on quality parameters, comparing with control fruits during eight months of cold storage at 0ºC and 85-90% RH. The results showed that 1-MCP treatments dramatically decreased the internal ethylene concentration and allowed to maintain the fruit firmness comparing the control. Moreover, both doses of 1-MCP were effective on protecting the color and acidity. The scald symptoms were controlled by both DPA and 1-MCP treatments better than control. The results showed that 650 and 325 ppb 1-MCP treatments protected overall quality better than DPA and control treatments during eight months of storage. Therefore, it is a recommendable application dose for the Granny Smith apple variety.
