Affecting factors on the efficacy of 1-MCP have been studied, nevertheless, there is no information describing whether the chamber loading affect the 1-MCP effectiveness when treating fruits. The purpose of this study was to evaluate the effect of the fruit-to-volume ratio of the treatment chamber on the ripening of papayas treated with 1-methylcyclopropene (1-MCP). Papayas were harvested at ripening stages 1 (up in different chambers with varying quantities of fruit per to 15% of yellow surface) and 2 (from 16 to 25% of yellow surface) and placed in different chamber. Treatments consisted of chambers loaded with 30, 60 or 120 cardboard boxes containing 12 papayas each (approximately 3.8 kg) corresponding to 18.75%, 37.5% and 75% of the fruit-to-volume ratio, respectively. A quantity of 300 mg of EthyBloc? was used at a concentration of 100 nL/L to generate 1-MCP gas per 1.868 m3 chamber for all treatments. Non-treated fruit was used as a control. The fruit was stored at 22 ºC for 10 days after 1-MCP treatment. When the fruit-to-volume ratio of the treatment chamber was at 75% the treatment did not delay changes in fruit firmness, respiratory activity or rotting. Otherwise fruit treated in the chambers with 18.75% or 37.5% fruit-to-volume ratio were not soft enough for consumption after 10 days of storage. The results suggest that increased box number leads to faster depletion of 1-MCP in the chamber. Thus, the results support the hypothesis that the fruit-to-volume ratio inside the chamber influences the efficacy of 1-MCP in the papaya fruit. Therefore, lower amounts of fruit and packing cardboard boxes in the treatment chamber are related to greater effects of 1-MCP.
