| 摘 要： | 通过测定抗性不同的马铃薯品种接种和未接种情况下叶片内防御酶活性,研究马铃薯品种对早疫病的抗性机制。结果表明,在接种处理后,各品种植株体内苯丙氨酸解氨酶（PAL）、过氧化物酶（POD）、多酚氧化酶（PPO）和过氧化氢酶（CAT）活性均提高,抗病品种酶活性增幅高于感病品种,说明上述4种酶与品种抗性有一定的关联。

| Abstract: | Activity of defensive enzymes of leaves in different resistant potato varieties after inoculation and non-inoculation was analyzed. The results showed that the activities of PAL,POD,PPO and CAT increased in all of varieties after inoculation. The increase of enzyme activities in resistance was higher than those in susceptible. Significantly PAL,POD,PPO and CAT in potato varieties were correlated with resistance to early blight. |
