Abstract

Cut gerbera flowers are sensitive to microbial contamination and have a short vase life. Silver nanoparticles are used in various applications as an antimicrobial agent. An experiment was conducted to determine the effect of different concentrations of SNP and chlorophenol to extend the vase life and postharvest quality of gerbera (Gerbera jamesonii cv. 'Balance') cut flowers. Cut gerbera flowers were kept in solutions containing 0, 5, 10 and 20 mg l-1 SNP and/or 0, 5 and 10 mM chlorophenol for 24 hr; then held in vase solution containing 250 mg l-1 8-hydroxyquinoline sulphate and 3% sucrose. The maximum vase life (16.33 days) was observed in flowers held in solution containing 10 mg l-1 SNP. The 5 mg l-1 SNP plus 10 mM chlorophenol and 10 mg l-1 SNP plus 5 mM chlorophenol inhibited bacterial growth in the vase solution. The minimum fresh weight loss (6.48gr) during the vase period was observed for flowers kept in solution containing 20 mg l-1 SNP. The results revealed that SNP and chlorophenol have the potential to extend vase life and enhanc the postharvest quality of cut gerbera cv. 'Balance' flowers.
