Involvement of ethylene in postharvest senescence of Boronia heterophylla flowers.

Treatment of cut flowering B. heterophylla (red boronia) stems with 10 micro l ethylene/litre for 72 h at 20 deg C induced flower senescence and abscission, and thereby reduced stem fresh weight and vase life. Pretreatment with 1-methylcyclopropene (1-MCP) reduced these ethylene effects. Treatment of B. heterophylla with 10 micro l ethylene/litre for a shorter 12-h period at 20 deg C did not affect vase life. Rates of endogenous ethylene production by B. heterophylla flowers increased in association with wilting during flower senescence.
