Background: Anthurium is belonging to the Araceae family. The effect of hydrogen peroxidase on vase life and postharvest quality of cut Oriental Trumpet hybrid lily “Manissa” was investigated. The results showed that the lower concentrations of H2O2 increased the vase life of a treated flower from 9.8 days (in control flowers) to 12.8 days in treated flowers. It’s reported that BA application delayed senescence in Roses, Irises and Tulips and prevent leaf yellowing in stocks and Gladiolus. The goal of this study was to investigate the effects and the best concentrations of H2O2 and BA on vase life of Anthurium andraenum.
Material and methods: In order to study the effects of various concentration of benzyladenin (1, 50, 100, 150, 200, 400 and 1000 ppm), hydrogen peroxide (5, 10, 15, 25, 35, 50 and 100 µM) on physicochemical characteristics of cut Anthurium andraenum flowers, three separated experiment were conducted based on completely randomized design with 5 replications. Some traits such as vase life, flower fresh weight, solution uptake rate, soluble sugar content and ion leakage were tested.
Results: The results of each 3 experiments showed that benzyladenin at rate 100 ppm significantly (p < 0.05) increased flower vase life (from 15 days in control to 19.6 days in 100 ppm BA) compared to control. In the 1st experiment, 25 µM of hydrogen peroxide had significant (p < 0.05) effect on vase life, solution uptake and fresh weight. Whereas, the higher concentration of H2O2 (50 and 100 µM) had no effect on measured traits. In the 2nd experiment, 5, 15 and 25 µM of H2O2 and in the 3rd experiment, all tested concentration of H2O2 had significant (p < 0.05) effect of evaluated traits. However, in the 3rd experiment, the effects of all treatments on soluble sugar content and ion leakage were significant (p < 0.05). In all 3 experiments, the effects of different concentration of hydrogen peroxide on vase life were better than control.
With the considering of the positive effects of the BA and H2O2 on solution uptake, using of these compounds can lead to preventing the water loss of the cut Anthurium flowers. Therefore, both compounds can positively affect the freshness and vase life of cut Anthurium flowers. Moreover, treatment of cut Anthurium flowers by various concentrations of BA and H2O2 showed a considerable increase in soluble carbohydrates and decrease in ion leakage. It’s found that application of 100 ppm BA and some rates of H2O2 (5, 10, 15 and 25 µM) are helpful to increase the freshness and vase life of the cut Anthurium flowers.
