Short postharvest vase life is one of the most important problems on the cut flowers. In this study we investigated the effect of some essential oils, citric acid, malic aid and nickel in extending the vase-life of lisianthus (Eustoma grandiflorum Mariachii. cv. Blue) flowers. The treatments were distilled water, nickel (0, 1 and 2 mM), essential oils of thyme (Thymus vulgaris) (50, 100 and 150 mg L-1), citric acid (0, 100 and 150 mg L-1) and malic aid (0, 1.5 and 2.5 mM). Results showed that solution containing 2 mM nickel+2.5 mM malic acid and 150 mg L-1 essential oils of Thyme could increase flower longevity as compared to control. The results also revealed that malic acid and nickel treatments increased cut-flower water absorption while decreasing ACC-oxidase (Aminocyclopropanecarboxylate oxidase) activity and premeability together with total delay of senescence and peroxidation of lipids. Chlorophyll content and ACC-oxidase activity in the cut flower in solution containing citric acid and essential oils were not significantly different than control. It is suggested the application of nickel, essential oils of Thyme and malic aid in preservative solutions for Lisianthus flowers maintained the vase life of flowers for a longer period.
