Abstract
The ice nucleation activation bacterial canker disease decreased the content of mobile p roline in pop larbarks, while caused the content of bark pectin to increase a bit. Though the double2glucose content in infected barkwas less than that in healthy one, the glucose content in the infected bark wasmore above 25 ℃ and less below 20℃ than that in the controlmaterial. When the infection was not serious, itmade the content of chlorophyll in infected bark increase, yet the serious infection made the host had opposite appearance.
