In the commercial fruit industry, formulations of 1-methylcyclopropene (1-MCP) are used to inhibit the action of ethylene in apple fruits destined for long-term storage. While the use of an ethylene action inhibitor impro ves firmness retention and reduces ethylene-related disorders, an unintended consequence is the failure of the fruit to ripen normally and attain characteristic fresh-quality attributes associated with taste and aroma (Blankenship and Dole, 2003). We examined reversing 1-MCP-mediated inhibition of ethylene action by using hydrogen peroxide (H2O2) to initiate normal ethylene response, and studied the effects of H2O2 on the regulation of aminocyclopropane carboxylic acid (ACC) synthase (ACS) and ACC oxidase (ACO), the two genes of ethylene biosynthesis, using polymerase chain reaction (PCR) techniques.
