摘要:
在不同条件处理下，对菌丝生长和病菌孢子萌发的影响进行系统的分析，研究不同温度及pH对榆白涩病病菌菌丝、病原孢子生长的影响。结果表明：榆白涩病病菌的生长速率受温度条件影响较大，5~30℃，菌丝生长量与温度呈正相关，25℃最适合菌丝生长；5~35℃，病原孢子的萌发率与温度呈正相关，适宜病菌孢子萌发的温度为30℃。pH值在3~11范围内病原菌丝均可生长；菌丝生长最适的pH值为9，pH值在3~11条件下孢子能够生长；最适孢子生长的pH值为8。
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.
