摘　　要：对亚麻炭疽病病原菌(Colletotrichumlini)进行了生物学特性研究。结果表明:温度、pH、光照对其生长都有一定的影响,菌丝最适生长温度为25℃;最适pH为8.0;持续黑暗条件下菌丝生长最好,光照不利于其生长;该菌在供试6种培养基中,在PSA上生长状况最好;碳、氮源对菌丝生长有一定的影响,碳源以山梨醇和蔗糖最适合;氮源以蛋白胨和牛肉膏最适合。The biological characteristics of the pathogen of flax Colletotrichum disease（Colletotrichum Lini） were studied.The results showed that temperature,pH and light affected the mycelial growth;the optimum growth temperature was 25℃;the suitable pH was 8;it grew the best under constantly dark conditions,light was not conducive to the growth of mycelium;the mycelia grew fastest in the PSA among the six testing culture mediums;both carbon and nitrogen sources had an effect on mycelial growth,the growth of mycelia was the fastest with sorbitol and sucrose;beef extract and peptone were the most suitable for the growth of mycelia.
