Abstract
The effect of 1-methylcycloprepene microbubbles (1-MCP-MBs) on reducing chlorophyll degradation, prolonging vase life and maintaining the quality of Dendrobium cv. ‘Burana Jade’ inflorescences was investigated. The inflorescences were immersed in 50 ppm 1-MCP-MBs or tap water (control) for 5 min and then held at 23 ± 1 ◦C for 12 days. The 1-MCP-MB-treated inflorescences exhibited increased water uptake and significantly higher fresh weight than the controls. The results also showed that 1-MCP-MBs remarkably delayed bud opening and flower abscission, accompanied by suppression of ethylene production and a lower respiration rate than that of controls. Additionally, the treatment maintained the green color (hue angle value was comparable to initial storage day) of the inflorescences by delaying chlorophyll degradation related to inhibition of chlorophyllase and Mg-dechelatase activities. 1-MCP-MBs prolonged the vase life of Dendrobium cv. ‘Burana Jade’ up to 12 days, which was 2-fold longer than that of the control (approximately 5 days only). The results suggest that 1-MCPMBs have the potential to be another alternative to conventional methods (fumigation) in prolonging vase life and maintaining the quality of Dendrobium orchids with the advantage of a shorter treatment time.
