Abstract

|
|
Ripening process and ethylene action mechanism of banana, known as a typical climacteric fruit, were investigated by the exogenous exposure to 1-Methylcyclopropene (1-MCP), gaseous ethylene action inhibitor, and ethylene. The rate of respiration, ethylene production, and chlorophyll degradation of peel in banana decreased by the pretreatment of 1-MCP for 12 hours before 10nL·L^(-1) ethylene exposure for 12 hours. In this case, as low concentration of 1-MCP as 0.6nL·L^(-1) was found to be effective in the retardation of ripening process. Iri contrast, when 10 nL·L^(-1) ethylene was pretreated for 12 hours followed by 1-MCP treatment, even high concentration of 1-MCP up to 40 nL·L^(-1) could not inhibited the ripening of banana. But when banana was exposed to 1-MCP and ethylene simultaneously, only 9 nL·L^(-1) 1-MCP was required to inhibit the ripening of banana. According to these results, it appeared that 1-MCP was a competitive inhibitor against ethylene in ethylene action receptor and binded into receptor site irreversibly once it reacted with receptor. Therefore, it would be speculated that the best ripening inhibition potential could be obtained with extremely low concentration if 1-MCP was applied to banana before pre-climacteric stage.
