The test run of the enzymes involved in the ripening of bananas found that the function of the enzyme PL, PC, PME, CX, ACo, Acs with the treatment. With Ethepone + 1- MCP and 1-MCP has been reduced over the fruit to ripen naturally be controlled. It will be seen that the treatment with 1-MCP will make the enzyme significantly reduced the most. But the work of the PME with Ethepone + 1- MCP treatment decreased the most , explained that the graph of the experiment is that Ethepone + 1- MCP and 1-MCP is a function of the enzyme is about. ripening of bananas decreased significantly.
