| 中文摘要: |
| 对采自我国不同地区、不同主栽葡萄品种‘红地球’、‘巨峰’及‘赤霞珠’上的12份葡萄霜霉病菌的致病力及孢子囊大小进行了比较和分析, 结果表明：采自不同葡萄品种的病原菌对感病葡萄品种‘奥迪亚无核’叶片的致病力具有明显差异, 其中‘巨峰’及‘红地球’来源的病原菌致病性较强, 明显大于‘赤霞珠’来源的病原菌致病力; 采自不同葡萄品种的霜霉病菌孢子囊大小存在一定的差异, ‘赤霞珠’来源的病原菌孢子囊明显大于‘巨峰’及‘红地球’来源的霜霉病菌孢子囊。上述结果表明, 采自不同寄主的葡萄霜霉病菌的致病力及孢子囊大小均存在一定程度的分化。 |
| 英文摘要: |
| Twelve samples from different planting areas were collected on ‘Kyoho’, ‘Red Globe’ and ‘Cabernet Sauvignon’, which were mainly grape varieties in China. The pathogenicity was tested and the size of sporangia was measured. The results showed that the ability of Plasmopara viticola isolates from different grape varieties to colonize Vitis vinifera ‘Otilia’ leaf tissue differed significantly. Isolates from ‘Kyoho’ and ‘Red Globe’ were significantly more aggressive than those from ‘Cabernet Sauvignon’. And sporangia size from different grape varieties differed significantly too. Isolates from ‘Cabernet Sauvignon’ were significantly bigger than others. In conclusion, there were significant differences in aggressiveness and sporangia size among isolates from different hosts. |
