The summer apple 'Anna' was treated with the ethylene inhibitor 1-methylcyclopropene (1-MCP) at concentrations of 0.01, 0.1 and 1 μl l-1 for times from 4 to 24 h at 20°C immediately after harvest, and the ripening of the fruit was monitored for 12 days at 20°C. Fruit were also treated with 1 μl l-1 at 20°C or at 0°C and then stored for 5 weeks at 0°C before ripening, or treated after 1, 4, and 8 days at 20°C and ripening monitored. Apples treated with 0.01 μl l-1 1-MCP ripened similarly to control apples. Apples treated with 0.1 and 1 μl l-1 1-MCP had lower ethylene production and respiration, slower loss of firmness and acidity, and less of a change in peel color from green to yellow. The inhibition conferred by 0.1 μl l-1 disappeared after 4 or 5 days and the apples ripened similarly to controls, while 1 μl l-1 treated apples remained less ripe throughout the ripening period. There was no benefit gained from treating the fruit for 24 h rather than 4 h. The apples responded to 1 μl l-1 at 0 or 20°C for 24 h similarly. If treatment with 1-MCP was delayed for 4 days, or ir the fruit were treated at the end of the storage period, there was little or no effect on fruit ripening. 'Anna' apple responded very well to 1-MCP by both delay of ripening during shelf life and maintenance of quality following storage. © 2002 Elsevier Science B.V. All rights reserved.
