Influence of 1-methylcyclopropene (1-MCP) generating pads and sulfur dioxide (SO2 ) germicidal bags on quality of Kyoho grapes in storage was studied. The unpacked grape (control group), SO2 germicidal bag-packed grapes (K group), and (K+MCP) group containing SO2 and 1-MCP were studied through determination of weight loss, stalk browning, firmness, total soluble solids, headspace gas concentrations, and sensory evaluation index. The experiment showed that the shelf-lives of the control group and the K group were 2 and 4 d, respectively, limited by severe dehydration and stem browning; in contrast, the germicidal bags containing 1-MCP pads were able to effectively extend the grapes'shelf-life to 8 days. It was concluded that the combined application of SO2 germicidal and 1-MCP treatments can extend shelf-life of grape at room temperature.
