摘要:
以蒲公英试材，采用培养皿法和水培法，研究了入侵植物三叶鬼针草(Bidens pilosa)水提液对蒲公英(Taraxacum mongolicum)种子萌发和幼苗生长的化感作用。结果表明：不同浓度的三叶鬼针草水提液处理均降低了蒲公英种子的发芽势、发芽率、发芽指数和活力指数，抑制了蒲公英幼苗的根长、苗高和叶宽生长，增加了丙二醛含量及相对电导率。说明入侵植物三叶鬼针草水提液对蒲公英有较强化感作用，使蒲公英种子萌发及幼苗生长受到抑制。
Abstract:
Taking Taraxacum mongolicum as material，lelopathic effect of aqueous extracts of Bidens pilosa on seed germination and seedling growth of Taraxacum mongolicum were studied.The results showed that after treatment with aqueous extracts of different concentration of Bidens pilosa，germination energy，germination percentage，germination index and vigor index of Taraxacum mongolicum seed were decreased，root length，height and width of seeding were inhibited，the content of malondialdehyde and the relative electric conductivity was increased.So the aqueous extracts of invasive plants Bidens pilosa had strong allelopathic effect on Taraxacum mongolicum.
