Today, the positive effect of alcoholic treatments on the quality and vase life of cut flowers has been demonstrated. The aim of this study was to evaluate the effects of four concentrations of acetaldehyde treatment (0, 1, 2, and 4%) on the delaying senescence of cut lisianthus. The results showed that all concentrations that used in the current experiment significantly increased vase life, reduced ethylene production, increased carotenoid content of petals and improve the process of flowers opening. Acetaldehyde 2 % showed the best performance compared to other treatments and was recognized as a superior treatment. It seems that the success of this experiment is associated with positive performance of acetaldehyde in decreasing ethylene synthesis
