摘要 为研究1-甲基环丙烯(1-MCP)对早熟苹果品种"藤牧1号"冷藏品质和冷藏后货架品质的影响,分别以0(对照)、500、1 000和1 500nL/L的1-MCP处理"藤牧1号"苹果,对各处理苹果在0℃贮藏期间,以及在冷藏40和60d后货架期间的品质进行了测定。结果表明:1-MCP抑制了"藤牧1号"苹果冷藏期间呼吸和乙烯释放速率;延缓了硬度和可滴定酸含量下降;延缓了苹果总酚含量、多酚氧化酶活性高峰的出现,抑制了丙二醛含量的升高;对可溶性固形物和维生素C含量影响不明显。此外,1-MCP还延迟了冷藏40和60d后7d货架期间果实的硬度、可滴定酸含量的下降,明显提高了果实好果率。从整体看,1 500nL/L的1-MCP维持"藤牧1号"苹果冷藏和货架期间品质的效果优于其它3个处理。 In order to determine the effects of 1-methylcyclopropene(1-MCP) on the quality of cold storage and the shelf life after cold storage of 'Mato' apple(Malus domestica c.v.Mato),an early mature apple variety,the different 1-MCP concentration of 0,500,1 000,and 1 500 nL/L was used to the apples of 'Mato' respectly,then the apples were stored at 0℃ for quality evaluating.The results showed that 1-MCP inhibited the respiration and ethylene release rate,delayed the decline of firmness and titrate acid,inhibited the emerge of the highest peak of total phenol and polyphenol oxidase activity,but had no significant effects on the content of soluble solid content and vitamin C,during cold storage.In addition,1-MCP also delayed the decline of fruit firmness and increased the good fruits rate at the 7 days shelf life after 40 days and 60 days cold storage,respectively.In general,1 500 nL/L was the most suitable concentration of 1-MCP for the cold storage quality and shelf life of 'Mato' apple.
