摘　　要：该实验研究了温度、pH、氮源和碳源对长孢直喙镰孢霉的影响。结果表明：（1）该菌最适生长温度为25~28℃,适宜生长温度为22~28℃,孢子萌发的最适温度为21℃;（2）最适生长pH为7.7~8.7;（3）在所选氮源中,蛋白胨为最适氮源;（4）在所选碳源中,乳糖为最适碳源。The effect was researched whenFusarium orthoceras App.et Wr. var.longius （Sherb.） Wr. grew in different temperature, or on medium which were different to pH value, nitrogen source or carbon source. The temperature experiment showed that the optimum growth temperature for the mycelium ranged from 25℃ to 28℃,the suitable temperature ranged from 22℃ to 28℃, the optimum temperature for spore germination was 21℃. pH value experiment showed that the optimum growth pH value was 7.7-8.7. Nitrogen source experiment showed that the optimum growth nitrogen source was peptone. Carbon source experiment showed that the optimum growth carbon source was lactose.
