摘要
水飞蓟软腐病是近年流行的一种毁灭性的病害,目前对该病研究的报导不多。通过对黑龙江省水飞蓟种植区的水飞蓟病害进行调查,发现该病发生普遍,危害严重。经对水飞蓟软腐病的病原菌进行分离、纯化及初步鉴定工作,并对分离得到的菌株按照柯赫式法则进行了致病性的测定,结果表明该病原菌与白菜软腐病的病原菌标准菌株胡萝卜欧文氏菌(Erwinia carotovora subsp. Carotovora(Jones1901)Borgey etal 1923)生长特性及致病特点基本一致。
Silybum is popular in recent years, soft rot is a devastating disease, the disease has currently little research reports. By investigation in Heilongjiang province silybum growing areas, the disease and found that the occurrence of the disease in general and serious. Test of silybum soft rot bacteria to carry out the separation, purification and identification of the preliminary work, and the strain isolated in accordance with Koch-law for the determination of the pathogenicity, the results shows that the bacteria the same as pathogenic bacteria standards Erwinia （Erwinia carotovora subsp. Carotovora （Jonesl901） Borgey et al 1923） and growth characteristics of pathogenic characteristics of the line.
