摘要：

Treatment of cut flowering Boronia heterophylla (red boronia) stems with 10 mu L ethylene/L for 72 h at 20 degrees 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 mu L ethylene/l for a shorter 12 h period at 20 degrees C did not affect vase life. Rates of endogenous ethylene production by B. heterophylla flowers increased in association with wilting during flower senescence.
