摘要
银胶菊Parthenium hysterophorusL.是危害严重的入侵植物,在我国主要分布于华南和西南地区,在山东新近发现的种群与南部种群在遗传上有明显的差异。本研究采集山东种群及3个南部种群(厦门、桂林和湛江)的种子,在同质园条件下比较不同地理种群的生长差异。结果表明,山东种群与南部种群在形态上(包括株高、茎直径、节间长和叶面积等)均存在显著性差异,特别是山东种群的头状花序直径显著小于南方种群。
Parthenium hysterophorus L.is a noxious invasive plant species.They are mainly distributed in south and southwest areas in China.The newly discovered populations in Shandong Province have great genetic differentiation from southern populations.Seeds of Shandong and three southern populations（Xiamen,Guilin and Zhanjiang） were collected.The growth characteristics of different geographic populations of invasive Parthenium hysterophorus under common garden conditions were compared.The results suggested that there were significant differences in morphology,including plant height,stem diameter,internode length and six leaf area.Capitulum diameter of Shandong was significantly smaller than that of the southern populations.These phenotypic data further indicated that there were significant genetic difference between the Shandong population and southern populations,which provided a basis for the development of rational management measures.
