Abstract
A study was carried out to look at the potential use of chitosan as a vase life preservation. Chitosan was also used to control pathogenic fungi and bacteria found in the vase solution after a substantial period the flowers were held in the vases. Cut chrysanthemum Dendranthema morifolium Ramat were treated with chitosan at 0 25 50 75 and 100 mgL-1 dissolved in 0.05 ascorbic acid and displayed in the Postharvest Lab with the environmental conditions 25_ deg C 70 RH and 15 mol m-2 s-1 light intensity from cool-white fluorescent lamps for 12 hours. The result showed that chitosan contained preservation vase solution at 25 and 50 mgL-1 significantly increased water uptake fresh weight and delaying wilt of cut flowers compared to the control. However chitosan at the higher concentrations 75 and 100 mgL-1 were not effective in controlling vase life of the cut flowers. The former two concentrations were also found to reduce the number of bacterial colonies and inhibited the fungal growth found in the vase solutions. In vitro observations found that chitosan at 50 75 and 100 mgL-1 inhibited the diameter of mycelial growth 2 days after incubation as well as reducing bacterial colonies.
