1-Methylcyclopropene extends Cymbidium orchid vaselife and prevents damaged pollinia from accelerating senescence.

A single postharvest application of 1-methylcyclopropene (MCP) prolonged vase life of Cymbidium orchids by 6 or 7 days, to approx equal to 19 days. It also prevented repeated applications of ethylene shortening the vase life of Cymbidium cut flowers. The anti-ethylene effect of one MCP treatment persisted throughout 3 successive challenges with ethylene at 5-day intervals. A supra-optimal concentration of MCP (500 ppb) showed no adverse effects. MCP was also effective in protecting Cymbidium orchids against accelerated senescence caused by damage to the pollinia. Individual flowers with damaged pollinia senesced even more rapidly than ethylene-treated intact flowers. In the presence of MCP, flowers with damaged pollinia had a vase life almost equal to that of undamaged flowers.
