This experiment was conducted to clarify the effects of 1-methylcyclopropene (1-MCP) on vase life of cut 'Blue Magic' iris. Pretreatment for 4 h with concentrations of 500 nL and 1000 nL 1-MCP, an inhibitor of ethylene action, inhibited the wilting and inrolling response of cut iris. The vase life of iris flowers of 500 nL or 1000 nL 1-MCP treatment was prolonged to 0.5 day compared to those held in distilled water (control). Vase life of iris showed no significant difference between $3{\mu}L{\cdot}L^{-1}$ ethylene exposure after 1-MCP treatment and control. 1-MCP treatment inhibited inrolling and increased fresh weight, water uptake, and water balance. The increase of fresh weight was high in 500 nL 1-MCP treatment and water uptake was increased by 1000 nL 1-MCP. Especially, iris flower without 1-MCP treatment dramatically decreased the water uptake as compared to the control for four or five days. Water balance of iris flowers held in water was changed to minus value faster than those with pretreatment of 1-MCP.
