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.
