Responses of native Australian cut flowers to treatment with 1-methylcyclopropene and ethylene.

Postharvest longevity of some cut flowers is shortened by exposure to ethylene gas. Adverse effects of ethylene may be prevented by treatment with 1-methylcyclopropene (1-MCP) gas. Responses of 14 different native Australian cut flowers to 1-MCP and ethylene applied at concentrations of 10 nl.l-1 and 10 micro l.l-1, respectively, were examined. Each gas was applied alone for 12 hours at 20 deg C and they were also applied in series. Vase lives of Ceratopetalum gummiferum, Chamelaucium uncinatum, Grevillea cultivars Kay Williams and Misty Pink, Leptospermum petersonii, Telopea cv. Shady Lady and Verticordia nitens were reduced by ethylene treatment. Treatment with 1-MCP generally protected these cut flowers against subsequent exposure to ethylene. The 1-MCP treatment usually did not extend their vase lives in the absence of exogenous ethylene.
