本文报导了1979—1982年对浙江省甘蔗花叶病毒的分布、传播、电镜观察、防治方法和病害对产量、质量影响的研究。结果表明,浙江省甘蔗花叶病毒至少存在两个株系,因均不能侵染约翰逊草(Sorghum halepenseL.),所以不是ScMV-I株系和MDMV-A株系。义乌地区花叶病的流行是和新植蔗区每年切种繁殖有关。种蔗带毒是ScMV的主要来源,蚜虫在传播流行上并不重要。人工汁液接种有30％发病。 受甘蔗花叶病毒感染的细胞经电镜检验,发现有线条状病毒粒子和风轮状及环状的细胞质内含体。 通过选种,可以将花叶病率压低到5％以下,鲜蔗和糖产量均有提高。地膜覆盖虽然不能压低发病率,但具明显的增产作用。温汤浸种的有效温度接近蔗芽致死的限温点,故不宜推广应用。药剂治蚜防病效果不显著。义乌地区现有栽培的品种虽均感病,但品种间的发病率和严重度有差异。
This paper reports the distribution of 1979-2002 sugarcane mosaic virus in Zhejiang Province, transmission, electron microscopy, control methods and diseases on the yield and quality of research. The results showed that there were at least two lines of sugarcane mosaic virus in Zhejiang province, which were not ScMV-I and MDMV-A lines because they could not infect Sorghum halepense L.. Yiwu mosaic epidemic is the area and the new planting sugarcane planting area each year breeding. Sugarcane poisoning is the main source of ScMV, aphids are not important in the spread of the epidemic. Artificial juice inoculation 30% of the disease. Cells infected with the sugarcane mosaic virus were examined electron microscopically and found that there were linearized virus particles and round and cytoplasmic inclusions in the wind. By selection, the mosaic disease rate can be reduced below 5%, fresh cane and sugar production have increased. Although mulching can not reduce the incidence, but with a significant increase in production. Wen Tang soaking the effective temperature close to the temperature limit of succulent death, it is not suitable for promotion and application. Pharmacological treatment of aphids disease prevention effect is not significant. Although the existing cultivated varieties in Yiwu are all susceptible, the incidence and the severity of the varieties vary.
