摘　　要：感染冰核细菌溃疡病的杨树树皮的果胶质含量比健株略高。病株树皮游离脯氨酸含量在总体水平上要低于健株。病株的单糖含量在25℃以上气温时高于健株,在20℃以下气温时却低于健株;在双糖含量上,基本上是健康植株高于患病植株。在病情轻微的情况下,病株树皮的叶绿素含量要高于健株,但在病情较重的情况下,病害能破坏叶绿素。The ice nucleation activation bacterial canker disease decreased the content of mobile proline in poplar barks, while caused the content of bark pectin to increase a bit. Though the double-glucose content in infected bark was less than that in healthy one, the glucose content in the infected bark was more above 25 ℃and less below 20 ℃ than that in the control material. When the infection was not serious, it made the content of chlorophyll in infected bark increase, yet the serious infection made the host had opposite appearance.
