Study interaction effect of Gerbera(Gerbera jamesonii) and Polyanthus(Polianthus tuberose) on longevity, quantitative and qualitaitive traits on vase solution

Gerbera and Polyanthus are two of very important in cut flowers global production. In this research,experiment on completely randomized block design with 12 treatment and 3 replications was carried out. The aim of this study was to investigate the effect of postharvest application of ethanol and sucrose on keeping quality and vase life of cut gerbera and polyanthus flowers. The cut flowers were harvested and after recut under water, were kept in preservative solutions containing sucrose 4%, ethanol 2.5% and combine sucrose and ethanol. The results showed that application of ethanol and sucrose increase vase life in cut gerbera and polyanthus flowers. Combination ethanol with sucrose increased significantly keeping quality and vase life flowers over control. Also, keeping gerbera and polyanthus cut flowers alone in preservative solution have better postharvest life than keeping them together.
