| 摘 要： | 以3个褐变程度不同的牡丹品种(‘乌龙捧盛’、‘太平红’、‘凤丹白’)为材料,分析了试管苗在增殖过程中总酚含量、苯丙氨酸解氨酶(PAL)、多酚氧化酶(PPO)和过氧化物酶(POD)活性的动态变化。结果表明:总酚含量及PPO、POD、PAL活性与牡丹试管苗增殖过程中的褐变密切相关。褐变越严重的品种,总酚含量和POD活性越低,PPO活性越高,PAL活性与牡丹的褐变程度未能表现出类似的规律。

| Abstract: | The dynamic changes of the contents of phenolic and the activities of phenylalanine ammonia lyase(PAL),polyphenol oxidase(PPO) and peroxidase(POD) were assessed during the differentiation process of three tree peony(Peaonia suffruticosa) cultivars('Wu Long Peng Sheng','Feng Dan Bai' and 'Tai Ping Hong') grown in vitro.A close relationship were observed between the tissue browning and the activities of phenylalanine ammonia lyase(PAL),polyphenoloxidase(PPO),and peroxidase(POD) activity,as well as phenolic co... |
