十字花科根肿病是由芸薹根肿菌(Plasmodiophora brassicae Woron)引起的侵染性病害。植株感病时,根部形成手指状或块状的畸形膨大。基于此,针对贵州省部分地区所采集的十字花科不同作物根肿病样本,通过形态观察法与地衣红染色法,分别对油菜、甘蓝、白菜3种作物的病原菌进行观察、讨论及分析。研究结果显示,油菜、甘蓝、白菜这3种作物的根肿病病原休眠孢子在形态和大小上存在一定的差异,以期该研究结果为该病菌的生物学研究及生理小种研究提供一定的参考。十字花科根肿病是由芸薹根肿菌(Plasmodiophora brassicae Woron)侵染引发的病害。芸薹根肿菌属于根肿
Crucifer clubroot is an infectious disease caused by Plasmodiophora brassicae Woron. Plant disease, the formation of the root of the finger or massive deformity inflated. Based on this, according to the samples collected from some areas of Guizhou province, the pathogens of brassicae, cabbage and cabbage were observed, discussed and analyzed by morphological observation and lichen red staining. The results showed that there were some differences in morphological and size of dormant spores between the three crops of rapeseed, cabbage and cabbage in order to provide some references for the biology and physiological races of this bacterium. . Crucifer clubroot is a disease caused by infection with Plasmodiophora brassicae Woron. Brassica root swollen belong to the root swollen
