油茶炭疽病菌的有性世代在1961—1963年首次发现于四川省泸县地区。经过接种和分离培养等试验证明,有性世代和无性世代病原菌同属于油茶炭疽病菌,与茶叶枯病菌 Guignardia camelliae (Gooke) Butler 相同。对病原菌生理特性进行了若干测定。初步肯定了阴雨、高湿促进有性世代的产生。它多在春秋两季形成,与无性世代关系亦很密切。有性世代病原菌具有致病力,但在自然情况下,作为初次侵染的可能性极小。
The sexual generation of Camellia anthracnose was first discovered in Lu county, Sichuan province from 1961 to 1963. After inoculation and isolation and culture experiments show that the sexual generation and asexual pathogens belong to the Camellia anthracnose bacteria, and the tea blight bacteria Guignardia camelliae (Gooke) Butler the same. Several physiological characteristics of the pathogen were measured. Preliminary confirmed the rain, high humidity to promote sexual generation. It is mostly formed in spring and autumn and has a close relationship with asexual generations. Sex-generational pathogens are pathogenic, but in the case of nature, there is very little likelihood of first-time infection.
