The storage of persimmons is an important tool to maintain the quality and to extend the fruit offer after harvest. The aim of this study was to evaluate the effect of preharvest application of aminoethoxyvinylglycine (AVG) and 1-methylcyclopropene (1-MCP) application before or after storage on the ripening control of persimmons cv. Fuyu during storage in controlled atmosphere (CA) at -0.5 ºC during 4 months. The treatments were: [1] control; [2] AVG (123 g ha-1) application and CA storage; [3] AVG application and 1-MCP (1.0 µL L-1) application after CA storage; [4] 1-MCP application before CA storage; [5] AVG application and 1-MCP application before CA storage; [6] 1-MCP application after CA storage. According to the results, the 1-MCP maintained higher fruit firmness after storage and during six days at 20 ºC. Highest firmness was obtained after six days at 20 ºC with application of 1-MCP after storage. The preharvest application of AVG is not efficient in maturation control of 'Fuyu' persimmons stored during four months in controlled atmosphere.
