摘要
研究表明金针菇绵腐病菌CladobotrunvariumNeesexSteud,为葡枝霉属,异形葡枝霉种。该病原菌分生孢子梗直立,分枝并轮生,每轮3～6个小梗。分生孢子卵圆形,单细胞或双细胞,大小为7.5～18.75μm×6.25～12.5μm。菌丝生长最适温度为20℃,最适pH值为7。孢子萌发最适温度为15℃,最适pH值为6。以2%寄主汁液最能刺激孢子萌发,金针菇生长过程中搔菌到芽出这一阶段是病原危害的关键时期。
Results showed that the pathogen of soft disease in Flammulium velutipes was Cladobotrun varium. Its conidiophores were upstanding, with verticillate branches (3～6 sterigmata for each round). Conidia produced were ovoid, monocellular or bicellular, with the size of 7.5～18.75μm×6.25～12.5 μm. The optimal temperature and pH for mycelial growth was 20℃and 7, respectively. Spores germinated best at 15℃and pH=7, treated by 2%extracts of Flammulium velutipes. The most important period for the pathogenic infecting and developing was from the stage of scraping to budding of Flammulium velutipes.
