摘要
对青稞病害标本的田间观察及实验室诊断,确定病害为细菌性病害。通过柯赫法则找到致病菌,致病菌革兰氏染色呈阴性,鞭毛染色呈不透明紫蓝色,极生一根鞭毛,致病菌为黄单孢杆菌属细菌,确诊病害为青稞细菌性条斑病。
Field observation and laboratory diagnosis of highland barley diseases,We can de-termine bacterial diseases.We found the pathogens bacteriawith the laws of the Koch＇s.Pathogen-ic bacteria was negativein Gram dye,it was the opaque purple bluebacteriaand born a flagellum in the bacterial flagellastaining.Thepathogenic bacteria areXathomonas,Thus we determined the Ti-bet highland barley diseases werebacterial leaf streak.
