This study was conducted to investigate the antimicrobial effect of chlorine dioxide (ClO2) on the vase life of cut rose 'Beast' (Rosa hybrida L.). Postharvest treatments to extend the vase life of cut roses were divided into two: holding solution treatment and pulsing solution treatment. In holding solution treatment, the cut roses were treated with preservative solutions containing tap water (TW, control), distilled water (DW), ClO2 2, 4, 6, and 8 μL·L -1, and compared with a commercialized antimicrobial compound of 8-HQS 200 μL·L-1. In pulsing solution treatment, cut roses were dipped into the ClO2solutions of 50, 100, 150, 200, and 250 μL·L-1for 60 seconds and were placed in DW. The air temperature was 18.4°C, RH 51.5%, and light (photosynthetically active radiation, PAR) 3.6 μmol·m-2·s-1with 12 hour day length. The longest vase life of cut roses was observed in the holding solution with ClO24 μL·L-1as 13.8 days and pulsing with 200-250 μL·L-1as 13.5-13.7 days, where vase life were extended four days longer than TW. Whereas, the inclusion of 8-HQS 200 μL·L-1in vase solution resulted in phytotoxicity.The relative fresh weight and water uptake have similar tendencies. Bacteria inhibition by ClO2and 8-HQS were very effective. But bacteria at TW and DW treatments on cut flower with stem were detected in 3.7 × 105CFU·L-1and 6.3 × 105CFU·L-1, respectively (without stem in DW 1.4 × 104CFU·L-1). The ClO2contents in holding solution of all treatments were scavenged in two-four days after treatment. This study indicated that ClO24 μL·L-1holding solution treatment and 200-250 μL·L-1pulsing solution treatment can be applied to extend the postharvest life of cut roses.
