首次报道了万年青(Rohdeajaponica(Thunb.)Roth)细菌性叶斑病和叶枯病在我国的发生。对分离到的4个菌株经致病性测定,电镜形态观察,培养性状和生理生化性状的测定,初步确定引起万年青细菌性叶斑病的病原为Erwiniaherbicola(Lohnis)Dye,叶枯病的病原为Pseudomonaspseudoalcaligenessubsp.rohdea
For the first time reported the occurrence of bacterial leaf spot and leaf blight of Rohdeajaponica (Thunb.) Roth in our country. Pathogenicity, electron microscopic observation, culture and physiological and biochemical characters of the four isolates were determined. The pathogen of the leaf spot caused by Evergreen was Erwinia herbicola (Lohnis) Dye. The pathogen of the leaf blight was Pseudomonaspseudoalcaligenessubsp. rohdea
