| 摘 要： | 通过对桑叶褐斑病病原菌在不同种类培养基培养、不同氮源与碳源、不同温度等6种条件下培养6天后，测定菌落直径，观察菌丝颜色和菌落形态，分析了桑褐斑病病原菌的生物学特性。结果表明，在室内培养条件下，不同的营养成分、 pH值、温度、光照都对菌丝的生长有影响。病原菌菌丝生长的最适宜培养基是燕麦片培养基，适宜生长温度范围是20～30℃，最适生长温度为25℃，光照对菌丝生长无显著影响，最适pH值为9～10，最适碳源为α-乳糖，最适氮源为尿素，菌丝在55℃水浴10 min后则不能生长。

| Abstract: | Through cultivating pathogenic fungi of mulberry brown rot disease under 6 conditions such as different media, temperature, carbon source and nitrogen source after 6 days, research on the biological characteristics of pathogenic fungus causing brown spot on mulberry leaves was conducted .The results showed that nutrition , temperature and pH had significant influence on mycelial growth . It was found that the best medium for mycelial growth was oatmeal medium , the proper temperature was 20-30℃, the optimal temperature for mycelial growth was 25℃, the light had no obvious promotion effect on mycelial growth .It was also found that the optimal pH was 9 to 10 , the best carbon source and nitrogen source for mycelial grow are α-Galoctaose and Carbamide , and the mycelial could not survive above 55℃more than 10 min. |
