Abstract: To guide the reasonable stack of fruits and vegetables in sealing plastic tent before storage, effects of different loading volumes (empty, full-tent and half-tent ), different loading containers (cartons, plastic boxes) and addition of fan in treated tent on 1-MCP concentration were studied using Nanguo pear and Jiubao peach as materials. The results showed that the maximum release quantity of 1-MCP was 3.775 μL/L in four hours under the airtight environment. The concentration of 1-MCP in the full-tent was higher than that in the half-tent. The concentration of 1-MCP in tent with plastic boxes as loading container was evidently higher than that with cartons. The concentration of 1-MCP in tent with the fan was higher than that without the fan. Addition of the fan was in favor of the uniform release of 1-MCP.
