| 摘 要： | 采用悬滴法和凹玻片法，对影响尖抱镰刀菌分生孢子萌发的环境因素进行了研究，结果表明。尖孢镰刀菌分生抱子萌发的最适温度为25℃，在小于5℃、大于45℃的条件下会失去萌发能力；弱酸条件促进分生孢子的葫发，其最适宜pH5.0；在相对湿度100％的条件下，病原菌分生抱子萌发率最高；碳源营养条件比氮源更有利于分生孢子萌发；光照可以促进分生抱子的萌发。 |

| Abstract: | Study was done on conidium＇s germination of Fusarium oxyporm, schleber which is one of pathogen fungus of seedling. The results showed that it will be lose ability of spouting beyond 5-45 ℃, and the Optimal is 25 ℃. Weak acid can promote conidium＇s germination, and the optimal pH is 5.0. It has relatively high expectation for humidity, the spouting rate is highest in RH 100%. Nutrition＇s conditions will benefit to its spouting at the moment, the carbon source is superior to the nitrogen source for its utilization. Light can promote conidium＇s germination. |
| Keywords: | Fusarium oxyporm Schleber Conidium's germination Environments factor Impact |
