With the objective of to extend the conservation period and commercialization of the 'Fuyu' persimmon fruit, alternatives to mantain fruits quality were tested. Tree experiments were accomplished to develop the work: 1) storage at the ambient temperature (AT): Temperature (T) of 18 ± 3°C and relative humidity (RH) of 80 ± 5%, with or without application of 1-MCP and evaluated in the crop, at 7 and 14 days; 2): cold storaged (CS): T of 0 ± 1,0°C and RH of 95 ± 5%, with or without application of 1-MCP, appraised in the crop and 45 + 3 days of simulated commercialization; and 3) CS and modified atmosphere (MA) with films of polyethylene of low density (PELD) with 80mm of thickness: T of 0 ± 1,0°C and RH of 95 ± 5%, with or without application of 1-MCP, appraised in the crop, 48 of CS and 10 days of simulated commercialization. The concentration of 1-MCP used in the specific treatments was of 500ppb/2h. The main physiochemical analyses accomplished were: pulp firmness (PF), color and epidermis browning (EB). The persimmon fruits of the experiment 2, maintained in CS, lost the commercialization quality before reaching 30 days of storage. The use of MA associated to CS, maintained the fruits with PF above 40 N, besides preventing the occurrence of EB. The yielded results showed that the maintenance of persimmon fruits quality can be kept for 48 days at CS and more 10 days of simulated commercialization at the environment temperature.
