1985—1987年观察了山茱萸炭疽病的症状表现,分离出了炭疽病菌。根据该病菌分生孢子的形态特征、培养性状和寄主较广泛等持点,鉴定为胶胞炭疽菌(Colletotrichum gloeosporioides Penz.)。生物学特性测定结果表明,分生孢子在温度为23—28℃、相对湿度100%及在1%蛋白胨,查彼氏培养液中萌发率最高;病原菌在以甘露糖为碳源的培养液上生长最好,在以硫酸铵为氮源的培养基上生长最差;分生孢子在黑暗和散光条件下萌发正常,荧光灯和黑光灯照射后对孢子萌发有影响,紫外光对分生孢子有强烈杀伤作用。
From 1985 to 1987, the symptom of anthracnose of Cornel was observed and anthrax was isolated. According to the morphological characteristics of the conidia of the bacteria, culture characteristics and host more widely held point, identified as Colletotrichum gloeosporioides Penz. The results of biological evaluation showed that conidia germinated at the temperature of 23-28 ℃, relative humidity of 100% and peptone of 1%, and Chaxingshi medium. The pathogen was grown on mannose as medium The best was ammonium sulfate as nitrogen source, the worst growth medium; conidia germination in the dark and astigmatism conditions normal, fluorescent and black light irradiation on spore germination have a strong ultraviolet light conidia strong Killing effect.
