Abstract:
We studied application of 1-methylcyclopropene (1-MCP) in various ornamentals, with the aim of finding optimum application temperature, dose, and duration. We also studied its competition with ethylene, and its synergistic effect with silver thiosulfate (STS). Ethylene (5μl l-1) was simultaneously applied with 1- MCP (15 or 150 nl l-1) at 4, 12 or 20°C to carnation (Dianthus caryophyllus cv. 'Yellow Candy'). At these application temperatures ethylene negatively affected flower quality. 1-MCP applied at 15 nl l-1 neutralized the adverse ethylene effects when applied at 4°C, but not at 12 or 20°C. However, when applied at 150 nl, l-1 1- MCP successfully eliminated ethylene effects at all temperatures. It seems, therefore, that 1-MCP is a better competitor with ethylene at low temperatures. 1-MCP pre-treatment (0.2-1μl l-1/2-20 h), followed by a subsequent exposure to ethylene (1-5μl l-1/24 h/20°C or 0.5μl l-1/12 days/12°C), significantly improved the quality of cut flowers (carnations cv. 'Yellow Goldy', Cymbidium orchids) and potted plants (Ficus 'Green island'), respectively. In Limonium hybrid 'Beltlaard' cut flowers the combined use of 1-MCP and STS resulted in highest quality. This combined treatment also enabled storage under sea transport conditions (8 days at 2°C). When applied alone, 1-MCP (0.4μl l-1/4 h) was also very effective in improving flower opening and the length of vase life in several rose cultivars. The results suggest that 1-MCP may be very useful in preserving quality of various ornamentals and that it protects against ethylene effects.
