摘要：

苹果树粗皮病（IBN）是一种常见的病害，锰过量和轮纹菌的侵染均能诱导粗皮病的发生。为明确2种诱因之间的关系，本试验在盆栽条件下，以这2种因素为诱因，研究2种诱因诱导下苹果叶片保护酶（SOD、POD、PAL、PPO和MDA）活性的变化，比较2种诱因影响的区别和联系。结果表明：MDA含量，SOD活性和POD活性的变化趋势基本一致；PAL对轮纹菌的侵染这一诱因表现的更为敏感；PPO酶活性基本不受锰过量诱因的影响。

Abstract:

There are two reasons causing the occurrence of rough bark disease on apple stem. Experiments were conducted under potted grown conditions, the activity of protection enzymes of the leaf were studied in the conditions of the over concentration of Mn and the inoculate by Botryosphaeria berengeriana f. sp. piricola. Results showed that the activities of superoxide dismutase (SOD), peroxidase (POD) and the malonaldehyde (MDA) contents all were strong at first and then declined. The maximum value of PAL by inoculate the Botryosphaeria berengeriana f. sp. piricola was earlier and higher than those of the over concentration of Mn. The over concentration of Mn had no effect on the PPO activities.
