研究了不同茄子品种接种黄萎病菌前后过氧化物酶 (POD)、多酚氧化酶 (PPO)、超氧化物歧化酶 (SOD)、苯丙氨酸解氨酶 (PAL)酶活性的动态反应及同工酶变化 ,结果表明在测定的大多数时间内 ,POD、PPO、PAL酶活性越大 ,抗性越强 ,供试的 3个茄子品种酶都出现一个高峰 ,而且抗病品种酶活性上升的较快。无论感病植株还是抗病植株 ,接种黄萎病菌后POD、PPO同工酶都出现新带 ,SOD同工酶没有出现新带 ,但酶量有所增加。这可为抗病育种提供理论依据。 The dynamic responses of peroxidase (POD), polyphenol oxidase (PPO), superoxide dismutase (SOD) and phenylalanine ammonia lyase (PAL) activity of different eggplant varieties before and after inoculation with Verticillium dahliae were studied. And isozymes. The results showed that in the most of the test period, the enzyme activities of POD, PPO and PAL were higher and the resistance was stronger. All the three eggplant cultivars showed a peak, and the enzyme activity of resistant varieties Rise faster. Both susceptible and resistant plants showed a new band of POD and PPO isozymes after inoculation with Verticillium dahliae, no new band appeared in the isozyme of SOD, but the amount of enzyme increased. This can provide a theoretical basis for disease-resistant breeding.
