以辣椒的 3个品种 (中研 10号、湘研 9号、湘研 5号 )为研究材料 ,采用测定酶活和同工酶电泳方法 ,研究辣椒感染炭疽菌后 ,多酚氧化酶 (PPO)、过氧化物酶 (PO)、苯丙氨酸解氨酶(PAL)的变化。结果表明 ,辣椒感染炭疽菌后 ,3种酶的酶活增加 ,有的PPO酶带消失或弱化 ,但是大部分PPO、PO同工酶酶带增多或加强 Three peppers (Zhongyan 10, Xiangyan 9 and Xiangyan 5) were used as materials to study the effects of enzyme activities and isoenzymes on the activity of polyphenol oxidase (PPO) , Peroxidase (PO), phenylalanine ammonia lyase (PAL) changes. The results showed that the activity of three enzymes increased and some PPO bands disappeared or weakened after the capsicum was infected with anthracnose. However, most of the PPO and PO isozyme bands were increased or strengthened
