摘　　要： 1-甲基环丙烯(1-Methylcyclopropene,1-MCP)可以与乙烯竞争结合乙烯受体,抑制乙烯的合成和生理作用的发挥。以新疆小白杏为试材。研究5℃和25℃贮藏条件下,1.0μL/L1-MCP对小白杏的果实采后生理和质量参数的影响。结果表明:1.0μL/L1-MCP处理可显著抑制贮藏期间果实乙烯释放量,延缓其呼吸跃变高峰的出现,保持果实的硬度、糖度和高Vc的含量,降低小白杏的细胞膜脂过氧化水平,抑制小白杏的腐烂率,延长货架期。 1-Methylcyclopropene （1-MCP） could competitive binding to the ethylene receptor, block ethylene synthesis and its physiology effects. Experiments were conducted to study effects of 1-MCP on postharvest physiology and quality assessments of apricots at 5 ℃ or 25 ℃ during storage. The results showed that 1.0 μL/ L 1-MCP significantly decreased the ethylene production, delayed the respiration peak.1-MCP treatment also maintained firmness and good quality of apricots, exhibited maintained the soluble solids content （SSC）, high content of Vc and good sensory evaluation compared to control. 1-MCP also reduces the intensity of membrane lipid peroxidation, decrease the decay rate and lengthen the shelf life of ‘Xiaobai＇ apricot.
