“Yueyinzaocui” pear ( P yrus pyrifolia cv. “ Y ueyinzaocui”) is a variety with good quality that is cultivated in the northeast area of G uangdong province in C hina and harvested from late J une to early J uly, but it only has a 1‐week shelf life. For the purpose of extending the shelf life of the “Yueyinzaocui” pear, 1 μL/L of 1‐ MCP (methylcyclopropene) was used to treat postharvest fruit. The results showed that fruit firmness continuously decreased; however, the respiration rate, ethylene production, β‐ GAL (galactosidase) activity and β ‐ GAL transcript level increased during storage at room temperature. Compared with untreated fruit, the decline of fruit firmness during storage was delayed in 1‐ MCP ‐treated fruit. Fruit respiration rate was decreased and the ethylene production peak was postponed by 1‐ MCP treatment. The activity of β‐ GAL and transcript level of β‐ GAL gene was reduced, and the shelf life of the “ Y ueyinzaocui” pear at room temperature was extended for 10 days by 1‐ MCP treatment. Practical Applications The purpose of this research is to extend the shelf life of “ Y ueyinzaocui” pear, and the results of this study showed that 1‐ MCP (methylcyclopropene) treatment extended its shelf life by 10 days at room temperature. “ Y ueyinzaocui” pear will rot rapidly in 1 week because of β‐galactosidase activity, which caused sale burden for farmers. So if the farmers use the method studied in this research, 1 μL/L 1‐ MCP treatment, it would reduce their pressure and may increase their income.
