Abstract:
Freshness-preserving effects of pulse treatments with nano-silver（NS） solution，a new-type anti-bacterial agent on cut lily flowers were investigated.The stem-ends of cut flowers were pre-treated with different concentrations of NS solutions（0，5，10 and 20 mg/L） for 24 h，and then immediately placed in glass vase containing de-ioned water.The results showed that NS pre-treatments had positive roles in extending the vase life of cut lilies，delaying the wilting of petals and leaves，improving water uptake and maintaining the fresh weight of cut lily stems，and the best concentration of NS was 10 mg/L NS.Further studies indicated that 10～20 mg/L NS could significantly inhibit the growth of Pseudomonas sp.and Enterobacter sp.，Acinetobacter baumannii and Achromobacter xylosoxidans，which were the 4 dominant bacteria identified from the postharvest cut lily flowers.
