| 摘 要： | 在1980-1985年,对我国主要苹果产区的潜隐病毒种类进行调查鉴定,基本明确渤海湾果区、黄河故道果区和西北高原果区主栽苹果品种普遍潜带褪绿叶斑病毒、茎痘病毒和茎沟病毒,未检出其他病毒。营养系矮生砧木也普遍潜带这三种病毒。解决潜隐病毒为害的主要途径是培育无病毒母本树,栽培无病毒苗木。这方面的研究工作正在进行中。

| Abstract: | The latent viruses of apple in the main apple-producing areas such as Bohai Gulf, Yellow River Vally and the Northwest China were identified by the double-budding method during 1980-1985. The results showed that the commer-cial cultivars including Delicious, Starking, Golden Delicious, American Sum-mer Peamain, Jonathan, Ralls, McIntosh, White Winter Peamain, Liaofu and Fuji were all infected by chlorotic leaf spot virus (CLSV), stem pitting virus (SPV) and stem grooving virus (SGV). In most cases, these three latent viruses were found to be complex infection. All trees of Delicious, Golden Delicious and Rainier were infected by these three latent viruses. The clonal dwarf rootstocks were also infected by them. These rootstocks included M2, M4, M7, M9, M26 and MM106.
In order to control damage of latent viruses in apple, the work on quarantine for mother tree and propagetions of virus-free seedlings is being carried cut. |
