Abstract
1-Methylcyclopropene (1-MCP), extending the longevity of ethylene-insensitive flowers in the Dendrobium flower, Red Sonia, was studied by pretreatments with 0 (control), 200 and 500 nl L-1 1-MCP for 6 hours at 20°C, then transferred to distilled water in an observation room (21±2°C, 70-80% RH, cool-white fluorescence lights for 12 hours). The results showed that 1-MCP significantly prolonged the vase life as determined by flower wilting.
Pretreatment with 200 nlL-1 1-MCP had the longest vase life at day 19.3, while flowers pretreated with air (control) had 17.4 days of vase life.
Additionally, 1-MCP gave better results in delaying the decreased fresh weight, respiration rate and ethylene production, and wilting of flowers and bud openings over the control treatment.
