Abstract
1-Methylcyclopropene (1-MCP), a competitive inhibitor of ethylene action ,was applied to kiwi fruit (Actinidia deliciosa C.F.Liang et A.R.Ferguson.'qinmei') at concentration (0.25),0.50,0.75μl/L after harvest at 20±0.5℃.The result showed that 1-MCP treatment significantly delayed and suppressed the onset and magnitude of fruit ethylene production rate. 1-MCP treatment inhibited loss of fruit firmness and delayed fruit ripening and softing. Meanwhile, 1-MCP-treated fruit had soluble solid equal to those in nontreated fruit. The result suggested that 1-MCP could be applied to enhance post-harvest quality of kiwifruit.
