| Research Abstract |
We investigated the antibacterial characteristics of flower vessels coated with silver nanoparticles and their effect on vase life of cut flowers (Ornithogalum thyrsoides and Delphinium sinensis) and woody ornamental cherry (Prunus x subhirtella cv. Keiou-zakua). In all cut stems, no bacterial proliferation was observed in vase solutions of vessels coated with silver nanoparticles throughout the experimental period, while numbers of bacteria in vase solutions increased in non-coated vessels. The amount of water uptake by stems in vessels coated with silver nanoparticles was greater than that of the flowers in non-coated vessels. Relative fresh weight of cut stems in vessels coated with silver nanoparticles was higher than that of the flowers in non-coated vessels. These results show that vessels coated with silver nanoparticles have antibacterial characteristics and suppress the decrease of water uptake and fresh weight of cut stems in cut flowers and woody ornamental cherry.
