Abstract:: Under the treatment of different temperature and pH conditions，the growth rate of Cylindrosporium ulmi（Fr.）Vassil.of Ulmus pumila L.and germination condition of pathogen spore were systemic studied，and analyzed the influence of temperature and pH on Cylindrosporium ulmi（Fr.）Vassil.of Ulmus pumila L．The results showed that the adaptability of Cylindrosporium ulmi（Fr.）Vassil.of Ulmus pumila L.on temperature condition was stronger.In 5~30℃，the mycelium growth rate exhibites positive dependence with temperature and growth time.The best temperature suited for mycelium growth was 25℃.In 5~35℃，the spore germination rate of Cylindrosporium ulmi（Fr.）Vassil.of Ulmus pumilaL.exhibites positive dependence with temperature and growth time.The best temperature suited for spore germination was 30℃.The mycelium also could grow on the pH range of 3 to 11,the optimum pH range was 9，the spore also could grow on the pH range of 3 to 11,The optimum pH range was 8.
