floretsThe vase life of dahlia florets was 8.0 days for the controls(Table 4). A dipping treatment with 0.5% DMSO did not extend thevase life. BA dipping treatments significantly extended the vase lifeby 1.8–2.6 days longer than the control. There were no large differ-ences in the vase life among different BA concentrations. However,the vase life in 100 M BA after immersing florets in solution was6.5 days, which was significantly less than controls.
