摘　　要：目的探究不同处理对红桃贮藏品质的影响,为红桃采后保鲜技术提供新途径。方法以红桃为实验材料,研究低温(5±0.5)℃条件下4种处理方法(CK,对照处理;S1,乙烯吸附剂;S2,1-MCP;S3,氯化钙)对红桃生理、营养和酶指标的影响。结果通过综合比较可知,乙烯吸附剂处理能够更好地降低果实的腐烂率,抑制红桃呼吸强度和乙烯生成速率的上升,延缓红桃硬度值、可溶性固形物含量和可滴定酸含量的降低,保持红桃SOD,CAT,APX,POD和PPO的活性。结论采后用乙烯吸附剂对红桃处理的贮藏效果最好,能够维持红桃较高的贮藏品质。The work aims to study the effects of different treatments on storage quality of Red Peach in order to provide new path for its postharvest storage technique.Red Peach was used as research material to study the effects of 4 treatments(CK,control treatment;S1,ethylene adsorbent;S2,1-MCP;S3,calcium chloride)on physiological,nutritional and enzymatic indices at(5±0.5)℃.From comprehensive comparison,treatment with ethylene adsorbent could better reduce the decay rate of fruit,inhibit the increase of respiration intensity and ethylene production rate,delay the decline of hardness,soluble solids content and titratable acid content,and maintain the activities of superoxide dismutase(SOD),catalase(CAT),ascorbic acid peroxidase(APX),peroxidase(POD)and polyphenol oxidase(PPO)of the Red Peach.The Red Peach treated by ethylene adsorbent after postharvest has the best storage effect,which can maintain its high storage quality.
