摘　　要：在实验室条件下,研究了不同的碳源、氮源、温度、光照、pH对玉竹黑斑病病菌的影响。结果表明:pH 7最适于菌丝的生长,pH 7～9适于孢子的萌发;光暗交替可以促进菌丝生长和孢子萌发;最适于菌丝生长和孢子萌发的温度均为28℃。Under the treatment of different carbon source, nitrogen sources, temperature, light and pH conditions, the growth rate of black leaf spot in Polygonatum odoratum （Mill.） Druce were studied. The results showed that the optimum pH for mycelium growth was 7, for spore germination was 7 to 9. The light and dark was advantage for mycelium growth and spore germination. The optimum temperature for mycelium growth and spore germination were both 28℃.
