N2 - 1-Octylcyclopropene (1-OCP)and 1-Decylcyclopropene (1-DCP),ethylene receptor inhibitors,analogues to 1-MCP,substituted with longer carbon chain in the 1-position were investigated in miniature potted roses cultivar ‘Lavender ’.All levels of both chemicals protected as compared to untreated plants.1-OCP and 1-DCP were the most e ¿ective at concentrations 1000 and 1500 nl l 1 ,which was ¿ve times higher than the concentration of 1-methylcyclopropene (1-MCP)(200 nl l 1 )used as a standard.The e ¿ectiveness of 1-OCP and 1-DCP was a function of time and temperature.At short (2 h)exposure times,the plants were highly sensitive to ethylene.Exposure time of 4 h for both 1-OCP and 1-DCP was su ¿cient to improve display life of miniature roses and longer exposures did not have any additional bene ¿cial e ¿ect. Apparently,exposing miniature potted roses to various temperatures did not have an in ¿uence on the performance of both 1-OCP and 1-DCP while low temperature at 5 reduced their performance.The reasons for di ¿erences in the e ¿ects of these compounds are discussed.
