Hercules and Mayfair, the effects of 1-methylcyclopropene (1-MCP) and ethylene have been investigated in a completely randomized design with three replications. First, cut flowers were fumigated at 0, 0.5, 1 and 1.5 µL L<sup>-1</sup> of 1-MCP concentrations for 24 h and then exposed to 1 µL L<sup>-1</sup> of ethylene for 18 h. This experiment was conducted at 20 ± 2°C, 60-65% RH, and a 12/12 h light/dark photoperiod. The results showed that 1-MCP treatment significantly increased postharvest durability in both cultivars, compared to the control. Also, results of 1-MCP treatment on leaf chlorophyll index in both cultivars, confirmed the role of 1-MCP in preventing external ethylene action as the main factor of Alstroemeria leaf yellowness. Based on data, Mayfair cultivar was more sensitive to ethylene in comparing to Hercules cultivar, although 1-MCP treatment reduced the active oxygen species in both cultivars by reducing biosynthesis and ethylene action or by direct increase in antioxidant enzyme activity.</strong></p> ER -
