摘　　要：目的:揭示全国鱼腥草主产区种质资源挥发油类物质多样性及其遗传基础,为选育优质、稳定的鱼腥草新品种奠定基础。方法:用气相色谱法测定22个种源鱼腥草中挥发油成分,并比较不同种源挥发油类物质峰面积、形态特征、分子标记之间的关系。结果:不同种源鱼腥草中既存在共有挥发油成分,又存在非共有挥发油成分,且共有挥发油成分峰面积种源间存在极显著差异,挥发油成分绝对峰面积、相对峰面积、RAPD分子研究的遗传距离分别聚类分析的结果基本一致,并可从形态特征上进行区分。结论:不同种源鱼腥草中挥发油类物质存在多样性,不仅与形态特征相关联,还具有一定的遗传基础,根据挥发油成分、形态与分子标记鱼腥草可划分为2个类型。Objective:To reveal chemical diversify of volatile oils in Houttuynia cordata from major producing areas in China and their genetic basis,lay a foundation for breeding a quality H. cordata variety. Method:The volatile oils in H. cordata from 22 provenances were determined by GC. And the relationship among the peak areas of volatile oils,biological characteristics and RAPD makers were analyzed. Result:There were common and special volatile oils in H.cordata from different provenances. The peak areas of commo...
