In this research, the effect of putrescine, spermine and spermidine on the vase life of cut red carnation (Red Corsa) and some physiological traits was investigated in horticultural laboratory of Azad University branch Rafsanjan in 2015. Therefore, an experiment based on completely randomized design with tree levels of 1, 2 and 3mM of putrescine and 0.5, 1 and 2mM of spermidine and 1, 2 and 3mM of spermine with 3 replications was performed. The recorded traits included vase life and morphological and physiological factors. The results indicated that all of the treatments increased vase life significantly compared to control treatment. On the other hand polyamines decreased ethylene production. Spermidineof 2 mM caused the highest vase life and the lowest ethylene production. All of the treatments especially 2 mM of Spermidine increased flower diameter and solution uptake content significantly compared to control treatment and 2 Mm of spermidine have been the most effective treatment. 1 and 2 mM of spermidine were only treatments that don’t reduce dry matter percentage significantly in the flowers. 2 mM of Spermidine caused the maximum amount of physiological traits as protein, chlorophyll and total soluble solids in the leaves of flowers. Therefore, 2 mM of Spermidine is suggested as the best treatment to increase postharvest life in Carnation cv. Red Corsa.
