**Effect of Cobalt, Acetylsalicylic Acid and Glutamine to Extend the Vase-life of Carnation (Dianthus caryophyllus L.) Flowers**

The reduction of the ornamental value of cut flowers is mainly due to their short vase life. In this study we investigated the effect of cobalt, acetylsalicylic acid and Glutamine to extend the Vase-life of carnation (Dianthus caryophyllus L.) flowers. The treatments were distilled water, cobalt (0, 1.5, 3 mM), acetylsalicylic acid (0, 1.5, 3 mM) and glutamine (0, 1, 2 mM). Results show that solution containing 1.5 mM cobalt, 1.5 mM acetylsalicylic acid and 2 mM glutamine could increase flower longevity in compared to control. Vase life in solution containing 3 mM cobalt, 3 mM acetylsalicylic acid and their combination didn’t have significantly difference than control and glutamine. The results showed that cobalt, acetylsalicylic acid and glutamine treatments increased cut flower water absorption, fresh weight and vase life, while decreasing MDA content, ACC-oxidase activity and membrane premeability together with total delay of senescence and peroxidation of lipids. Present results suggest the application of cobalt, acetylsalicylic acid and glutamine in preservative solutions for carnation flowers maintained the vase life of flowers for a longer period.
