摘要:

2006—2007年在山东农业大学中药材试验站栽培的药用植物草决明上发现一种新病害,定名为草决明荚枯病。该病主要危害荚果,荚果受害后均从尖端开始发病,使受害部分变褐枯死,不能正常结籽。从多个发病荚果中共分离到11株相同真菌分离物,针刺法接种荚果后均可引起荚果发病。根据该病原菌形态学特征、培养性状并结合rDNA-ITS序列分析,将引起草决明荚枯病的病原鉴定为葡萄座腔菌,这也是首次在草决明荚果上发现由该种病菌引起的病害。

Abstract:

A new disease named legume dieback of Cassia torawas first found in Taian of Shandong Province during 2006—2007The disease was mainly harmful for legumes. Initially, the tips of diseased legume were gray\|green and legume die back with the disease development. The diseased part of legume could not seed. Eleven strains were isolated from diseased legumes and the pathogenicity was tested in the legumes. Based on morphological characteristics, pathogenicity test and the sequence of ribosomal DNA\|ITS, the pathogen was identified as Botryosphaeria dothidea Ces et de Not. This is the first report of legume dieback of Cassia tora.

Key words: legume dieback of Cassia tora, symptoms, pathogenic identification, Botryosphaeria dothidea
