| 摘要: |
| 通过田间自然鉴定和田间人工接种鉴定的方法,研究了我国葡萄属20个野生种或变种对白粉病的抗性。结果表明,在葡萄白粉病人工接种的喷雾、涂抹和干粉方法中,以2×105个/mL的悬浮孢子液进行田间喷雾接种, 21 d后调查接种鉴定结果为最佳方法,田间自然鉴定和人工接种鉴定及叶片和果实对白粉病的抗性存在显著的相关关系。 |

| Abstract: |
| The methods of Resistance to grapevine powdery mildew [Uncinula necator(Schweintitz) Burrill] of 20 Vitis species native to China,were studied by field
natural evaluation and field artificial inoculation, including spraying, smearing, and
powdering. After 21 days identification was investigated and the results showed that the
inoculation concentration 2×105 spores/mL by the spraying of grapevine powdery
mildew was the best method in three inoculations under field conditions. There was a
significant positive correlation coefficient of the resistance to the disease between field
natural evaluation and field artificial inoculation as well as both the leaves and the
berries of grapes. |
