| 摘 要： | 秃瓣杜英是我国江南地区广泛栽培的园林绿化树种。从2003年开始,在杭州地区秃瓣杜英叶枯病发生严重,发病株率达20%以上。该病害主要在春、秋季为害新梢嫩叶,导致叶片枝条枯死,树势衰退,严重的整株树枯死。通过对侵染秃瓣杜英病原菌的形态学观察、致病性测定及rDNA ITS序列分析,证明侵染秃瓣杜英的病原菌为芒果球座菌Guignardia mangiferae,其无性型为Phyllosticta anacardiacearum。

| Abstract: | Elaeocarpus glabripetalus (Elaeocarpaceae) is widely cultivated as an ornamental tree in southern China. Since 2003, a leaf blight has seriously occurred on the plants in Hangzhou area, Zhejiang Province. The rate of the diseased plant was more than 20%. The disease mainly infects the top of plants in spring and autumn, causing twigs growing slowly, degenerating and even wilting to death of the whole plants. The causal agent was identified as Guignardia mangiferae (anamorph: Phyllosticta anacardiacearum) based on its morphological characteristics, pathogenicity and rDNA ITS sequence analyses. |
