<p>Recently, there has been an increasing need to prolong the quality of matured fruits to promote the distribution of fresh fruits to consumers and processing facilities. Studies have shown that 1-methylcyclopropene (1-MCP), an inhibitor of ethylene, can maintain the firmness and quality of several fruits for a long duration. Therefore, the aim of this study was to examine the effect of 1-MCP treatment on the firmness, rind color, and decay rate of the Japanese pear ‘Shizukisui’. Results showed that 1-MCP treatment alone and 1-MCP treatment after precooling significantly maintained the firmness of mature fruits compared with untreated fruits. However, the presence or absence of ethylene addition did not significantly affect fruit firmness; moreover, 1-MCP treatment after precooling tended to reduce moisture loss in immature fruits. Regarding the peel color of the fruits, 1-MCP treatment alone and 1-MCP after precooling treatment increased the L*, b*, and C* values of mature fruits but reduced the values in immature fruits. Compared with the control group, the 1-MCP treatment caused a decrease in the decay area of wounded ‘Shizukisui’ and ‘Kosui’ fruits and decreased the decay rate of wounded ‘Kosui’. Overall, this study showed that 1-MCP treatment maintained the firmness and peel color of Japanese pear and reduced its decay rate.</p>
