Postharvest Life of Cut Lisianthus Flowers as Affected by Silicon, Malic Acid and Acetylsalicylic Acid

M. Kazemi, M. Asadi and S. Aghdasi

Abstract:
Vase life is one of the most important problems on the cut flowers. Combinations of silicon, malic acid and acetylsalicylic acid were used as preservative mixture for cut lisianthus and their effect on regulation of senescence was examined. The vase were placed in chambers at 19°C, relative humidity about 70% and 14 h photoperiod that was maintained using fluorescent lamps (light intensity of 15 μmol m-2 sec-1) at the top of the corolla. In this study, the recorded traits included vase life, total chlorophyll content (SPAD reading), anthocyanin leakage, malondialdehyde content and ACC-oxidase activity. The results showed that combination silicon, malic acid and acetylsalicylic acid treatments increased the vase life compared to the control. The vase solution containing 1.5 mM silicon and 2 mM malic acid with 1.5 mM acetylsalicylic acid significantly the malondialdehyde accumulation and ACC-oxidase activity reduced in the same solution while membrane stability was improved.
