Hydrogen peroxide (H2O2) is an important signal molecule
involved in diverse plant developmental processes. Oriental x Trumpet hybrid lily, lilium
Manissa' was used to investigate the effects of H2O2 in the vase solution on the vase life and
keeping quality of cut flowers. The results show that the optimum concentration (600 mu M) caused
an increase in vase life. from 9.8 days in control to about 12.8 days. Concentrations of 800 and
1200 mu M resulted in negative effects. Concurrently, 600 mu M H2O2 resulted in the maximum
flower diameter and the maximum number of days for full flower opening. Moreover, the H2O2
scavenger ascorbic acid (ASA) or the H2O2 inhibitor diphenylene iodonium (DPI) reversed the
positive effects of 600 mu M H2O2 on vase life and flower diameter. Treatments with 600 mu M H2O2
delayed leaf and petal senescence and flower opening for some days. Additionally, 600 mu M H2O2
treatments significantly reduced the relative degree of decline of leaf relative water content
(RWC), leaf chlorophyll, petal water-soluble carbohydrate and cut flowers fresh weight. However,
petal electrolyte leakage in 600 mu M H2O2 treatments showed the minimum variations. Together,
these results indicated that H2O2 treatments at the proper dosage prolonged the vase life of cut
lily and enhanced postharvest quality by retarding the degradation of RWC, chlorophyll,
carbohydrate as well as cut flowers fresh weight and simultaneously keeping membrane integrity.
