Changes of some physiological and biochemical activities in cut Hedychium coronarium spikes during vase-holding life.

The dry weight of cut H. coronarium flowers and their soluble protein and carbohydrate contents increased at first, but decreased after full bloom, when held in vases of water. Superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) activities decreased at first and then increased, the activity of SOD peaking at the full bloom stage, while the activities of CAT and POD peaked when the flower stalks began to bend. Malondialdehyde (MDA) content increased continuously, but more rapidly when the SOD, CAT and POD activities began to decrease again. Plasma membrane permeability was initially stable, but increased markedly after full bloom when the MDA content increased rapidly. It is suggested that active oxygen metabolism is responsible for the postharvest senescence of cut H. coronarium flowers.
