Abstract: In order to screen suitable storage method for prunes storage, taking‘Laike’prunes produced in Bayingol Mongolian Autonomous Prefecture in Xinjiang as test material,（0±1） ℃ cold treatment as the control, the prunes were treated with 1-MCP, 1-MCP+ozone and 1-MCP+ozone+humidification respectively. The influences of different treatment methods on the prunes storage quality were compared and analyzed by measuring the quality indexes such as good fruit rate, pH value, hardness, TSS content and VC content. The results showed that, compared with the control,the treatments of 1-MCP, 1-MCP+ozone, 1-MCP+ozone+humidification could inhibit the increase of decay and pH value of prunes, maintain the high good fruit rate, fruit hardness and TSS content, but the effect on the VC content was not significant. And the treatment of 1-MCP+ozone+humidification kept the good fruit rate and better hardness, and 1-MCP alone treatment better maintained the TSS content of prunes. It showed that the appropriate concentration of1-MCP fumigation treatment could better maintain the storage quality of prunes, and ozone and humidification treatments had positive effect on the fresh-keeping of prunes after 1-MCP fumigation.
