Résumé

The storage of 'Tahiti' limes (Citrus latifolia) at low temperatures enables the extension of the commercialization period. However the loss of the skin green colour and the occurrence of chilling injuries prevent such benefits. The purpose of this work was to verify the efficiency of 1-methylcyclopropene (1-MCP), an inhibitor of ethylene action, during the cold storage of 'Tahiti' lime. Fruits were treated for 12 hours with 1-MCP at concentrations of 0 or 1.0 microL L-1 and then stored at 5 or 10 °C for 30, 60 and 90 days (+ 3 days of simulated marketing at 20 °C). Applications of 1-MCP conserved the colour of stored fruits at 10 °C over a period of 30 days. Fruits treated with 1-MCP and stored at 5 °C presented less respiration than non-treated fruits. High levels of ethanol and acetaldehyde were observed after 60 days in non-treated fruits. The occurrence of chilling injuries on fruits was not verified after a 30-day storage period, however after 60 days of storage, 40 to 58% of fruits kept at 5 °C presented chilling injuries. All fruits stored at 5 °C presented chilling injuries after 90 days.
