Cut rose (Rosa hybrida, cv. Sonia) flowers, with or without leaves, were treated with an aqueous solution of 500 mg l-1 2-hydroxy-3-ionene chloride polymer (HICP), a quaternary ammonium compound, for 4 h, and then transferred to tap water. The pulse treatment with HICP was markedly effective in extending the vase life of cut flowers with leaves, but was ineffective for those without leaves. Irrespective of the presence or absence of leaves, HICP suppressed the reduction in fresh weight of cut flowers with time. The amounts of water uptake and water loss by the cut flowers with leaves decreased until the 4th day after harvest, but both values were higher in cut flowers treated with HICP than in those without treatment. Hydraulic conductance decreased with time, and HICP suppressed this decrease, although the number of bacteria in the lower segment of the flower stem was not decreased by HICP.
