| 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．obtusatus)，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。

| 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 gametophytes 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. compressus , E. okamurae and K ( n ) = ll = 2V ( H ) + l V + 2J + 5 ( 3v +2i ) +m(h) in E. giraldii, respectively. |
