This study was conducted to investigate the effect of 1-methylcyclopropene (1-MCP) and ethylene-absorbent on the qualities of Prunus mume fruit. Prunus mume fruits were stored without film packaging (Cont), packed in LDPE film (Cont-P), and packed with ethylene-absorbent (Cont-PE). Fruits were treated with 1-MCP (1 ppm) for 24 hr at $1^{\circ}C$. After treatment, fruits were packed in LDPE film (MCP-P) and with ethylene-absorbent (MCP-PE) and then stored at $1^{\circ}C$ for 8 weeks. Total soluble solids increased during storage but decreased after 6 weeks while total acidity decreased during storage. Cont was almost completely decayed after 8 weeks of storage while Cont-P, Cont-PE, MCP-PE, and MCP-P were 46, 69, 83, and 5% decayed, respectively. L value decreased but a value increased during storage in all samples. Firmness of peel and flesh of samples decreased gradually for 8 weeks. Respiration rate did not show any significant difference among samples. Ethylene production of Cont showed $0.05{\mu}L/kg/h$ but immediately after 1-MCP treatment, it showed $0.02{\mu}L/kg/h$. Oxalic and malic acids decreased while citric acid increased during storage; fructose and glucose substantially decreased after 8 weeks whereas sorbitol and sucrose increased upto 4 weeks and then decreased thereafter. Based on these results, packing the fruits treated with 1-MCP could extend the freshness of Prunus mume fruit.
