Scanning Electron Microscopy Observation of Stem Rust in Bamboo Stems ZHOU Shiguo, GAN Xihua, JIANG Li (Electron Microscopy Room, Nanjing Forestry University, Nanjing 210037) The morphology of spore of sporidoid pathogen in bamboo stem and the distribution of mycelium in pathological tissues and its pathogenesis were studied by scanning electron microscope . It was observed that only the top of cysts of sporulated cells expanded when the summer spores of the fungus of the bamboo rod started to produce, and the surface was smooth and warty.
