中文摘要: 以青椒为试材，选取1-甲基环丙烯（1-methylcyclopropene，1-MCP）、SO2 保鲜剂、乙烯吸收剂3 种保鲜剂，通过两两组合的形式（1-MCP+SO2 保鲜剂、1-MCP+乙烯吸收剂和SO2 保鲜剂+乙烯吸收剂）对青椒进行处理，测定贮藏期间青椒的品质和生理相关指标。结果表明，1-MCP+SO2 保鲜剂处理组保鲜效果较好，贮藏20 d 后，青椒果实还原糖含量、VC 含量、可滴定酸含量和叶绿素含量分别高于对照组15.17 %、20.36 %、16.32 %、5.68 %，且对照组青椒果实的失重率、腐烂率和乙烯呼吸速率分别是1-MCP+SO2 保鲜剂处理组的2.7、2.9、1.8 倍，可见3 种保鲜剂组合对青椒还原糖含量、VC 含量、可滴定酸含量和叶绿素含量的下降均有抑制作用，并且可降低青椒果实的失重率、腐烂率和乙烯生成速率。

Abstract:Green pepper was selected as the test material，and three preservatives，1-methylcyclopropene（1-MCP），SO2preservative and ethylene absorbent，were adopted in the form of pair-pair-combination（1-MCP+SO2 preservative，1-MCP+ethylene absorbent and SO2 preservative+ethylene absorbent）.The green pepper was treated to determine the quality and physiological indexes during storage.The results showed that the 1-MCP+SO2 preservative treatment group had better preservation effect.After storage for 20 days，the reducing sugar content，VC content，titratable acid content and chlorophyll content of green pepper fruits were higher than that of the control group by 15.17%，20.36%，16.32%and 5.68%，respectively.And the weight loss rate，decay rate and ethylene respiration rate of green pepper fruits in the control group were 2.7，2.9 and 1.8 times higher than those in the 1-MCP+SO2 preservative group，respectively.It could be seen that the combination of three kinds of preservatives can inhibit the reduction of reducing sugar content，VC content，titratable acid content and chlorophyll content of green pepper，and can reduce the weight loss rate，decay rate and ethylene production rate of green pepper fruit.
