Abstract
1-Hexylcyclopropene (1-HCP) and 1-octylcyclopropene (1-OCP) are potent ethylene inhibitors. Pre-treatment of Kalanchoë blossfeldiana Poelln. cultivar Alexandra flowers with these compounds delayed inrolling and extended the display life of flowers. 1-OCP was most effective at concentrations of 200 and 500 nl l-1 while 1-HCP was effective at 1000 and 2000 nl l -1 being five to ten fold higher than the concentration of 1-methylcyclopropene (1-MCP) (200 nl l-1) used as standard/control. 1-OCP however, prolonged the display life of individual flowers to almost 10 days and was significantly better than 200 nl l-1 1-MCP. The effectiveness of 1-HCP and 1-OCP was a function of time and temperature. At short (0.5 h) exposure times, the flowers were highly sensitive to ethylene that translated to a commensurate decrease in display life. Exposure time of 2 h for both 1-HCP and 1-OCP was sufficient and any longer treatments did not have any additional effect. Apparently, treatment temperature did not have an influence on the performance of 1-HCP and was depicted by lack of significance on display life at all temperature levels (5, 10, 15, 20°C). 1-OCP was effective at 15 and 20°C while lower temperatures reduced its performance. Reasons for differences in effects of these compounds are discussed.
