The objective was to investigate the change of fruit characteristics by 1-MCP treatment to "Ichibakouji". Maturity evaluation by elasticity index was carried out using a nondestructive hardness tester. The fruit weight, elasticity index, and ethylene production amount were measured every 2 to 3 days, respectively, and the freshness retention effect of 1-MCP was investigated. Fruit weight decreased with no difference between treated and untreated plots. Both areas decreased to about 94% on the 20th day. Elasticity index decreased in both treated and untreated plots, but treated plants showed higher values. The reason for this is considered to be that the increase in the amount of ethylene produced in the treated plot was slower than in the untreated plot. Ethylene production was high in the untreated plot on the 8th day after harvesting and high in the treated section after 14 days. Using 1-MCP as a "market street" led to a moderate increase in the amount of ethylene production and an extension of the freshness retention period. The extension period was about 2 to 3 days.
