| 中文摘要: |
| 作者于2009年在贵州麻风树栽培基地栽培的麻风树上发现一种叶部新病害，定名为麻风树叶枯病。该病主要危害植株叶片，叶片受害后初期产生椭圆形或不规则病斑，后期病斑连成片，常引起叶片过早脱落。从贵州罗甸麻风树栽培基地采集了16个叶枯病标样，经分离培养获得13个真菌分离物。通过致病性测定，证明菌株PE06为麻风树叶枯病的病原菌。通过形态学观察及其rDNA-ITS序列分析，将贵州麻风树叶枯病的病原菌鉴定为小孢拟盘多毛孢菌Pestalotiopsis microspora，这也是首次在麻风树叶片上发现由该病菌引起的病害。 |
| 英文摘要: |
| A new leaf disease named as leaf blight of barbadosnut (Jatropha curcas), was first found in 2009 in Guizhou Province of China. The disease mainly infected leaves. The spots on diseased leaves were initially oval to irregular, then the spots gradually expanded and finally coalesced to form large leaf blight spots, and the seriously infected leaves easily defoliated earlier. Thirteen isolates were cultured from 16 leaf blight samples of barbadosnut collected from Luodian Plantation in Guizhou Province. The strain PE06 was investigated to be the pathogen based on pathogenic test and identified as Pestalotiopsis microspora according to the pathogen’s morphology and rDNA ITS sequence analysis. This is the first report of leaf blight of barbadosnut. |
