摘要
本文首次对毛茛科唐松草属(Thalictrum L.)植物陕西唐松草(T.shensiense W.T.Wang et S.H.Wang)、秋唐松草(T.thunbergii DC)、短梗箭头唐松草(T.simplex L.var.brepvies Hara)、城口唐松草(T.fargesii Franch ex Fin.et Gangdp)、绢毛唐松草(T.brevi-sericeum W.T.Wang et S.H.Wang)等5种植物的花粉形态作了光学显微镜及扫描电镜观察。确认这5种植物花粉外壁均为颗粒状雕纹,从而为唐松草属植物的分类提供了科学依据。
The present paper deals with the pollen morphology of 5 species ofThalictrum plants which are T. shensiense W.T. Wang et S.H. Wang, T. thu-nbergii DC, T. simplex L. var. brevipes Hara, T. fargesii Fran.ex Fin.et Gan-gep, T. brevisericeum W.T. Wang et S.H. Wang. The pollen grains were allexamined under light microscopes and scanning electron microscopes. Theirexine proved to be granules, which fact provided scientific basis for classi-fying Thalictrum plants.
