摘　　要：通过研究温度和pH值对黄杨炭疽病病原菌的影响,发现温度对菌丝体生长影响较大,最适生长温度为25～28℃,过低或过高的温度都对菌丝体生长不利;菌丝体对pH值反应不太敏感,在pH3～12条件下皆可生长,但最适pH值为6。By studying the influences of temperature and pH value on the mycelial growth of anthracnose of Enonymus japonicns L. ,found the temperature had a relatively large influences. The tested strain could grow with optimum growth temperature being 25℃ to 28℃, and too low or too high temperature were unfavorable; mycelium had a less sensitive response to pH value,it could grow with the pH values in 3-12 and the optimum pH for mycelial growth was 6.
