Abstract

Abstract: The effects of ethylene and its inhibitor，1-methylcyclopropene（1-MCP）treatments on the flower opening，ethylene production，and the expression of ethylene biosynthesis- and perception-related genes in cut rose‘Samantha’were investigated. The results showed that 1-MCP pre-treatment or post-treatment substantially inhibited ethylene-caused increase of ethylene production in petals，gynoecia，and receptacles. 1-MCP treatments also substantially inhibited the expression of Rh-ACS3，Rh-ACO1 and Rh-ETR3 genes in petals and gynoecia，but of only Rh-ETR3 in receptacles. The results indicated that the effect of competitive inhibition of 1-MCP on ethylene occurred mainly in petals，gynoecia and receptacles，and the effect was substantial，regardless the treatment was performed before or after ethylene treatment.

Key words: cut rose, ethylene, 1-MCP, gene expression
