摘要
【目的】研究1-甲基环丙烯(1-MCP)对养心菜的贮藏期及品质的影响。【方法】通过0.5、1.0、1.5、2.0μg/m31-MCP处理的养心菜,4℃贮藏条件下观察呼吸速率、失重率、叶绿素含量、VC含量在贮藏期的变化。【结果】用1-MCP处理能明显延长养心菜贮藏期并保持品质,且以1.5μg/m3效果最好,贮藏期达30 d,比对照组延长了12 d;贮藏终期,与对照组比较呼吸速率为其0.39倍、叶绿素含量为其2.43倍、VC含量为其1.09倍、失重率为0.84倍,是初期呼吸速率0.19倍、叶绿素含量为0.27倍;VC含量为0.54倍。【结论】1-MCP通过抑制养心菜的呼吸作用,延长贮藏期1.67倍,同时更好地保持了养心菜品质。
【Objective】It aims to research the influence of 1-Methylcyclopropene(1-MCP) on the storage period and the quality of Aizoon Stonecrop herb.【Method】When it was treated by 4℃ storage conditions and four concentrations of 1-MCP(0.5,1,1.5,2μg/m3),the change of the respiration rate,the weight loss rate,the contents of chlorophyll,the contents of vitamin C in Aizoon Stonecrop herb during the storage period was observed.【Result】Treated with 1-MCP,it could significantly prolong the storage period and maintain the quality of Aizoon Stonecrop herb.Even the best effect was revealed in the contents of 1 MCP(1.5 μg/m3).The storage period could be prolonged as long as 30 days,12 days longer compared with the control groups.Compared with the control group under the storage conditions of 1.5 μg/m3,it was found that the respiratory intensity is 0.398 times;loss rate was 0.84 times;chlorophyll content was 2.43 times;the content of Vc was 1.09 times.【Conclusion】When the respiration of Aizoon stonecrop herb was inhibited by 1-MCP,its storage period could be extended 1.67 times and meanwhile the good quality remained retained.
