- Abstract
In order to improve the vase life characteristics and postharvest quality of Alstroemeria cut flowers cv. Hercules and Mayfair, the effects of 1methylcyclopropene (1MCP) 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 L1 of 1MCP concentrations for 24 h and then exposed to 1 µL L1 of ethylene for 18 h. This experiment was conducted at 20 ± 2°C, 6065% RH, and a 12/12 h light/dark photoperiod. The results showed that 1MCP treatment significantly increased postharvest durability in both cultivars, compared to the control. Also, results of 1MCP treatment on leaf chlorophyll index in both cultivars, confirmed the role of 1MCP 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 1MCP treatment reduced the active oxygen species in both cultivars by reducing biosynthesis and ethylene action or by direct increase in antioxidant enzyme activity.
