CaCl2 has been known to have an ability to suppress the senescence of cut flowers. In the present study, we investigated the effect of CaCl2 on the antioxidative enzyme activities in cut flowers of Rosa hybrida and Dendrobium phalaenopsis during postharvest storage. The activities of superoxide dismutase, catalase, and peroxidase in the cut flowers with treatment of 45 mM CaCl2 in vase water were higher than those without CaCl2 during storage. These results suggest that calcium ion can contribute to the quality maintenance of cut flowers through activating the antioxidative enzyme activities.
