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。
In 2009, the author found a new leaf disease on Jatropha curcas cultivated in the Jatropha curcas cultivation base in Guizhou, and named it as Jatropha curcas leaf blight. The disease is the main damage to plant leaves, leaf damage early after the generation of oval or irregular lesions, the lesion even into the film, often lead to premature leaf shedding. Sixteen leaf blight standard samples were collected from Jatropha curcas cultivation base in Guizhou Province, and 13 fungal isolates were isolated and cultured. By pathogenicity test, strain PE06 was proved to be the pathogen of Jatropha curcas leaf blight. Morphological observation and rDNA-ITS sequence analysis indicated that the pathogen of Jatropha curcas leaf blight in Guizhou was identified as Pestalotiopsis microspora, which was also found for the first time on the leaves of Jatropha curcas.
