摘要
通过对酿酒葡萄病株与健株在叶绿素含量、光合速率、经济产量、品质等方面的比较结果表明 :葡萄感染卷叶病后 ,其叶片中的叶绿素含量、光合速率都明显低于健康品种 ,株产比对照减少近 4倍左右 ,同时病株浆果含糖量偏低 ,而酸度上升 。
The grapevine leafroll disease is the most devastating disease of grapevine in many grapevine productive areas. It was investigated that infected grapevines are lower than healthy ones in chlorophyll content, photosynthesis and econmic production, and fruit of GLRV had less sugar and higher acide content. These result in a weak grapevine quality.
