| 摘 要： | 采用形态学和分子鉴定方法确定采自建德市大同镇茶园茶枝的致病菌为镰刀菌Fusarium incarnatum与茶炭疽菌Colletotrichum fructicola,鉴定并报道F. incarnatum为茶树致病菌。龙井43和中茶108离体叶片及茎秆用于两种病原菌致病力分析试验,结果显示,F. incarnatum对龙井43嫩叶及茎秆具有较强侵染力,是造成该茶枝茎秆病害的主要致病菌,并且可能与C. fructicola共同侵染茶树叶片。因此,在今后茶树病害识别与防控方面需要密切关注。

| Abstract: | The pathogens of diseased tea branches in tea garden of Datong town, Jiande city were identified by morphological and molecular methods. Two fungal pathogens were identified, namely Fusarium incarnatum and Colletotrichum fructicola. F. incarnatum here was reported as the pathogen of tea trees. Leaves and stems of Longjing43 and Zhongcha108 were used in the experiment to analyze the pathogenicity of the two pathogens. The results show that F. incarnatum had strong pathogenicity to young leaves and stems of Longjing43, indicating it is the main pathogen causing relative disease. F. incarnatum and C. fructicola might infect tea leaves together which needs more attention in tea disease recognition, control and prevention in future. |
