Experiments were conducted to determine the effect of dipping open `Scania' carnation flowers in aqueous solutions of benzyl adenine (BA) (0, 13, 26, 39, and 52 mg·L-1) and gibberellic acid (GA3) (0, 10, 20, 50, and 100 mg·L-1) on flower vase life. Flowers were dipped for two minutes in BA or GA3 solutions, and visual symptoms of flower senescence were periodically recorded based on distortion, discoloration, and permanent wilting of the petals. In general, visual symptoms of senescence progressed more slowly in BA-treated flowers than in GA3 - treated and control flowers. One week after treatment, the only flowers with satisfactory appearance (slight or no petal distortion, wilting or discoloration) were those treated with BA at the rate of 13 mg·L-1 and GA3 at the rate of 50 mg·L-1.
