摘要/Abstract

摘要： 为探讨1–甲基环丙烯（1-MCP）处理对番茄果实低温贮藏期间冷害和抗病性的影响，以绿熟期的‘浙杂205’番茄为试材，用1 μL · L-1的1-MCP在20 ℃下处理番茄果实6 h，然后将其置于3 ℃冷藏14 d后转入20 ℃后熟16 d。结果发现，1-MCP处理加重了冷藏番茄后熟期间的冷害，但是延缓了硬度和可滴定酸度的下降，推迟了番茄红素的增加和乙烯峰的出现，诱导了多酚氧化酶和过氧化物酶活性，同时降低了几丁质酶和β–1,3–葡聚糖酶的活性。虽然1 μL · L-1的1-MCP处理延缓了冷藏番茄果实的后熟，却加重了番茄后熟期间冷害和病害的发生，不适合在番茄冷藏中应用。

Abstract: In order to determine the effectiveness of 1-methylcyclopropene（1-MCP）on chilling injury and disease resistance of tomato fruit after cold storage. Green mature‘Zheza 205’tomato fruit was treated by 1 µL · L-1 1-MCP before being stored at 3 ℃ for 14 days then ripen at 20 ℃ for 16 days. The quality and physiology of tomato fruit were investigated. 1-MCP treatment not only promoted chilling injury and disease index，but also increased the activities of polyphenol oxidase and peroxidase. 1-MCP treatment retarded the peak of ethylene and the increase of lycopene，maintained higher content of titratable acidity and firmness. The activities of chitinase and β-1,3-glucanase were also inhibited by 1-MCP treatment. This study indicated that 1 µL · L-1 1-MCP delayed tomato fruit ripen，but promoted chilling injury and disease incidence，and showed that it could not be considered for commercial use in tomato fruit after cold storage.

Key words: tomato, storage, 1-methylcyclopropene, chilling injury, disease resistance
