摘要

To understand the factors that induce floral senescence in gerbera, this study has investigated the effects of various chemical agents on flower senescence. The experiment was carried out to investigate the effect of different concentrations of silicon, acetyls ahcylie acid and glutamine on keeping quality and vase life of gerbera cut flowers. The vase were placed in chambers at 19°C, relative humidity about 70% and 14th photoperiod that was maintained using fluorescent lamps (light intensity of 15 μmol m ~(-2) sec ~(-1)) at the top of the corolla. The recorded traits included Vase life, total chlorophyll content (SPAD reading), anthocyanin leakage, malondialdehyde content, ACC- Oxidase activity and water absorption. The experiments show that: 3 mM silicon had no significant influence but 1 and 2 mM silicon caused an increase on vase life. The results showed that silicon, 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.
