Effects of Nanosilver Treatments on Vase Life of Cut Flowers of Carnation (Dianthus caryophyllus cv. 'White Liberty’)

Carnation (Dianthus caryophyllus) is one of the most cultivated flowers around the world for producing of cut flowers. This paper assessed the efficacy of nanosilver (NS) as an antibactericidal agent in extending the vase-life of cut flowers of carnation (Dianthus caryophyllus L.). Vase solutions were consisting of NS concentrations in 5, 10, 20, 40 and 80 ppm included sucrose 6 percent added in all treatments. Results showed that all NS treatments were combined with sugar extended the vase life of carnation flowers significantly compared with control. Observations indicated that NS treatments inhibited the growth of microorganisms in vase solution and considerably extend the vase-life of cut flowers of carnation.
