京郊大蒜病毒病发生普遍,主要症状为条纹花叶、矮化和叶片扭曲畸形。病体细胞中含大量线状病毒粒体和风轮状内含物。线状病毒粒体长度范围为250—1875nm,以长度550—800nm粒体居多。其中长700—800nm的粒体被鉴定为大蒜花叶病毒(GMV),回接脱毒大蒜叶片产生条纹花叶症状。血清学鉴定表明GMV与洋葱黄矮病毒(OYDV)有近缘关系。长度500—600nm的粒体可能为大蒜潜隐病毒(GLV),回接脱毒大蒜不产生花叶症状。下述两种病毒为京郊大蒜的主要病毒。此外,个别标样含烟草花叶病毒,但不是大蒜的主要病毒。对800nm以下线状病毒粒体归属尚待研究。应用营养茎尖、生殖茎尖和根尖分生组织培养技术,可以脱去上述主要病毒,获得脱毒大蒜。
The outskirts of garlic disease in the common occurrence of garlic disease, the main symptoms of striped mosaic, dwarf and leaf distortion. The body cells contain a large number of linear virus particles and wind wheel-like inclusions. Linear virus mitochondria length range of 250-1875nm, with a length of 550-800nm the majority of the body. Among them, the long 700-800nm granule was identified as Garlic Mosaic Virus (GMV), and the virus-free garlic leaves produced stripe mosaic symptoms. Serological identification indicated that GMV is closely related to Oryza dwarf virus (OYDV). The particles with the length of 500-600nm may be the garlic latent virus (GLV), and the retrovirus garlic does not produce mosaic symptoms. The following two viruses are the main virus in the suburbs of garlic. In addition, individual samples contain tobacco mosaic virus, but not the major virus in garlic. At least 800nm linear virus particles belonging to the study yet to be studied. Application of nutrition stem tips, tips and shoot apical meristem culture technology, you can take off the above-mentioned major virus, access to virus-free garlic.
