Abstract:
This experiment revealed significant influence of cobalt (Co), silicon (Si), Acetylsalicylic Acid (ASA) and Sucrose (SUC) at different concentrations on the vase life of Argyranthemum cut flowers. In this study three levels of cobalt (0, 1 and 2 mM), three levels of silicon (0, 1.5 and 3 mM), three levels ASA (0, 1.5 and 3 mM) and two levels of SUC (0 and 2.5% w/v) were applied in a factorial arrangement, carried out in a complete randomized design on 324 Argyranthemum cut flowers. The recorded traits included Vase life, total chlorophyll content (SPAD reading), anthocyanin leakage, Malondialdehyde (MDA) content, ACC-oxidase (ACO) activity and water absorption. Results show that solution containing 2 mM cobalt, 1.5 mM silicon, 1.5 mM ASA and 2.5% w/v SUC could increase flower longevity in compared to control. Vase life in solution containing 3 mM silicon, 3 mM ASA and their combination didn’t have significantly difference than control. The results showed that silicon and ASA 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 our results suggest the application of silicon, ASA and cobalt in preservative solutions for Argyranthemum flowers maintained the vase life of flowers for a longer period.
