【摘要】 国产苔藓植物的核型研究,目前尚未见到任何报道。本文对中国产绢藓属4种植物进行了核型研究。观察了配子体有丝分裂中期的染色体和异染色体。4种植物的染色体数目均为11。钝叶绢藓(E.ob-tusatus),密叶绢藓(E.compressus),东亚绢藓(E.okamurae),的核型公式为K(n)=11=2V(H)+2J+6(4v+2i)+m(h),陕西绢藓(E.giraldii)为K(n)=11=2V(H)+V+2J+5(3v+2i)+m(h)。4种植物的核型均为首次报道。更多还原

【Abstract】 This paper deals with karyological studies on four species of the genus Entodon from China. The metaphase and heteropycnotic chromosomes in mitotic cells of gameto-phytes were observed. All the four species showed the same chromosome number of n=11. Their karyotypes were formulated as K(n) = 11 = 2V(H) + 2J+6(4v + 2i) +m(h) in E. obtusatus, E. campressus, E. okamurae and K(n) = 11 = (h) in E. giraldii, respectively.更多还原
