| 摘 要： | 经田间自然鉴定、接种鉴定及室内离体接种鉴定结果表明：葡萄对霜霉病抗性与品种叶内的含水量、可滴定酸、还原糖、淀粉、水解氨基酸、游离氨基酸含量无显著相关，与叶背气孔密度、气孔开闭程度也无相关，而外施高浓度蔗糖及邻苯二酚却显著降低霜霉菌的致病力。

| Abstract: | The resistance of grapevines to Plasmopara viticola was not significantly related with water,triable acid , sugar, hydrolysis amino acid, free amino acid contents in leaves, leaf stoma densitv and stomawidth and length. The pathogenicity of Plasmopora vitlicola was reduced when high concentrations of su-crose and catechol were sprayed to grape leaves. |
