Strawberry quality declines rapidly after harvest. Deterioration may be accelerated by ethylene and is potentially increased, decreased or unaffected by the ethylene inhibitor 1-MCP (1-methylcyclopropene). We have examined the effects of 0.01, 0.05, 0.1 and 1ml l^-1 of ethylene and 0.01, 0.1, and 1.0ml l^-1 1-MCP o­n thequalityattributes and respiration rates ofstrawberriesstored at 0 or 5 °C. Ethylene did not affect the rate of rot development. However, calyxqualitywas significantly reduced by exposure to 0.1 or 1.0ml l^-1 ethylene. Treatment with 1 m l l^-1 1-MCP protected the calyx tissue from these effects. Exposure ofstrawberriesto 0.01, 0.1 or 1.0ml l^-1 1-MCP did not affect overall fruit acceptability but did slightly increase the rate of rot development. 1-MCP treatment reduced ethylene production by the fruit. Increased production of CO₂ by 1-MCP treated fruit was associated with the earlier o­nset of rots. Although the results suggest that blocking ethylene perception interferes with disease resistance in strawberries,there was o­nly a small effect o­n total storage life. It was concluded that neither the removal of low levels of ethylene from the storage environment nor the treatment with 1-MCP are likely to be cost effective methods of extending strawberrystorage life.
