| 中文摘要: |
| 以54个鲜食葡萄品种为试材,调查统计不同葡萄品种的霜霉病发病程度、发病速率、落叶率和新梢成熟度。结果表明,不同葡萄品种对霜霉病的抗性存在明显差异,欧美杂种品种群的葡萄对霜霉病的抗性显著高于欧亚品种群;病情指数与落叶率、新梢成熟度呈极显著的相关性,与发病速率之间关系不显著。 |
| 英文摘要: |
| The infective degree,infective rate,defoliation rate,and shoot maturation degree of different species of grapes were investigated using 54 fresh-eating grape species as materials.The results showed that there were significant differences in the resistance to the grape downy mildew among the species.The resistance of the cultivar Vitis vinifera L.×V.labrusca L.to the grape downy mildew was significantly higher than that of V.vinifera L..There was a significant correlation between infective index and defoliation rate and shoot maturation degree,but no significant correlation was observed between infective index and infective rate. |
