摘　　要：为了明确高粱炭疽病病菌(Colletotrichum sublineola)的生物学特性,采用生长速率法对其生长条件进行研究。结果表明,高粱叶煎汁培养基最适于病菌生长,其次为淀粉琼脂培养基、胡萝卜培养基;该病菌适宜生长的温度范围为20~35℃,最适温度为28℃,病菌的致死温度为54℃,10 min;病菌在pH 3~10均能生长,适宜pH为8~10,最适pH为9;适宜碳源为麦芽糖,适宜氮源为蛋白胨和酵母粉,铵态氮不利于菌丝生长;全黑暗条件更有利于菌丝生长。明确高粱炭疽病菌的生物学特性,以期为该病害的有效防治提供理论依据。In order to identify the biological characteristics of mycelium of anthracnose disease of sorghum,the growth rate method was used to study its growth conditions.The results showed that the agar medium of sorghum leaf decoction was most suitable for the mycelium growth of Colletotrichum sublineola,followed by starch agar medium and carrot agar medium.The suitable temperature was between 20 and 35℃,and the optimum temperature was 28℃,while the lethal temperature was 54℃,10 min;The mycelium can grow in the range of pH 3-10,the appropriate pH-value of medium was 8-10 and the optimal pH was 9;The suitable carbon source for mycelium growth of C.sublineola was maltose,and the suitable nitrogen source were peptone and yeast powder.The biological characteristics of C.sublineola was studied in order to provide theoretical basis for effective control of the disease.
