| 摘 要： | 对5个菊芋品种的总酚含量、PPO活性、POD活性与褐变强度进行了测定。结果表明：不同菊芋品种的总酚含量、PPO活性、POD活性与褐变强度差异显著，其中3个北方品种的各项指标均高于2个南方品种。相关性分析显示，4个外形呈不规则瘤形品种的PPO活性与褐变强度之间呈显著正相关，相关系数r=0.982。褐变主成分分析表明：PPO活性、POD活性和总酚含量这3个变量共同影响菊芋的褐变。

| Abstract: | The phenol content and activities of polyphenol oxidase(PPO)and peroxidease(POD),and browning degree in 5 artichok(Helianthus tuberosus L.)cultivars were tested.The result indicated that phenol content,activities of PPO and POD,and browning degree existed significant variation among the 5 artichok cultivars,and indexes of the 3 northern cultivars were higher than that of the 2 southern cultivars.The correlation analysis showed that the relation between PPO and browning degree is positively significant among... |
