摘　　要：旨在对胶孢炭疽菌的生物学特性及花椒炭疽病的有效防治提供理论依据。本研究采用菌丝生长速率法、培养皿玻片法和浓硫酸法,就不同环境条件对胶孢炭疽菌菌丝生长和孢子萌发的影响进行研究。结果表明:胶孢炭疽菌的菌丝生长和孢子萌发的最适温度分别为25℃和20℃;在p H 8时,最适宜其菌丝生长和孢子萌发;光暗交替有利于其菌丝生长,全光照下促进孢子萌发;相对湿度越大孢子萌发率越高。可见,尽可能的避免或错开胶孢炭疽菌生长发育的适宜温度、p H值、光照条件和相对湿度方能有效的防治花椒炭疽病的发生和蔓延。The aim is to provide a theoretical basis for the biological characteristics of Colletotrichum gloeosporioides and effective prevention of Pericarpium zanthoxyli anthracnose. In this research, the mycelium growth rate method, Petri dish slide method and concentrated sulfuric acid method was used to study the influence of different environmental conditions on Colletotrichum gloeosporioides growth and spore germination. The results showed that： the optimum temperature of Colletotrichum gloeosporioides mycelial growth and spore germination was 25℃ and 20℃, respectively; pH 8 was the most suitable condition for the mycelial growth and spore germination; alternating light and dark was beneficial to mycelial growth and full sunlight promote to spore germination; the higher the relative humidity, the greater the spore germination rate. Therefore, the occurrence and spread of pericarpium zanthoxyli anthracnose could be controlled effectively when suitable temperature, pH value, light condition and relative humidity were avoided in Colletotrichum gloeosporioides growth.
