This study aims to investigate the proper mixing treatment concentration of ozone (O3) and sucrose to preserve and extend the vase life of the cut rose flowers ‘Dominica’. The vase solution was prepared using tap water, 3% sucrose, ozone 5.5 mg L-1, and 3% sucrose with ozone 5.5 mg L-1. The vase life was the highest in the tap water and ozone treatments at 16.3 and 16.1 days, respectively. The vase life of ozone with sucrose treatment was 6.9 days, which was 9.4 days lower than that of the control. Compared to a single treatment, the vase life termination symptoms for ozone with sucrose treatment decreased petal wilting and increased bent necks. Relative fresh weight and vase solution uptake increased up to 4 days after treatment and decreased from 2 days before vase life termination. The rate of change in petal color was high in L*, a*, and b* for the sucrose treatment than after harvest, and low for the ozone treatments. The maximum relative flower size increase rates after treatment were 195% in the control, 186% in the sucrose treatment, 171% in the ozone treatment, and 155% in the ozone with sucrose treatment.
