【摘要】 在2005～2007年,从我国一些油菜产区获得油菜黑胫病害感染植株,病原物分离鉴定的结果显示,其致病真菌为侵染性较弱的 Leptosphaeria biglobosa,具有强侵染性的菌种 L.maculans 尚未从上述产区获得。在菌落形态上(包括在营养基质上的生长速度和色素合成等),中国的 L.biglobosa 菌株与欧洲的 L.biglobosa 菌株具有很大相似性。更多还原

【Abstract】 Diseased oilseed rape debris with phoma stem canker symptoms was collected from three provinces in China during 2005-2007 and the causal fungi were isolated from them. Cultural identification and PCR detection suggested only Leptosphaeria biglobosa was isolated from these samples and the more aggressive L. maculans was not found. There were no differences in the range of cultural characteristics(e.g. pigmentation and in vitro growth)between L. biglobosa isolates from China and those from Europe (L. biglobosa ’brassicae’).更多还原
