Abstract: Effects of pretreatments by UW ( ultrasonic wave) and UW + PS ( preservative solution) on indexes related to water conditionsmembrane stability of cut Nymphaea caerulea flower were studied during wet storage. The result showed that compared with the control, the vase life was postponed, water conditions were improved, which including the increase in fresh mass of flower stem, the p romotion of equilibrium between water absorp tions and loss, the water absorption rate and the water potential in different parts of flower stem. Meanwhile, the productions of O2· and MDA in petals were retarded, but SOD and CAT activities of petals were increased by two types of ultrasonic wave pretreatment during wet storage. The effect by UW + PS was better than that by UW alone, it showed the synergism effects.
