Abstract
This paper deals with the results of the karyological studies on fifteen moss species. In order to obtain vivid plants, a new method of culture was employed. In the cultures of these mosses, innovations were rarely produced. The regenrated young shoots from the fragments of stem or from the removed leaves were used for the karyological studies. In these karyological studies, metaphase and heteropycnotic chromosomes in the mitotic cellsof gametophyte were observed. The chromosome numbers and karyotypes were determined as follows:Bryoxiphium japonicum K(n)=14=V(H)+2V+2J+8(4v+4j)+v(h)Blindia japonica K(n)=14=2V(H)+2V+2J+6(4v+2j)+2m(h)Dicranella heteromalla K(n)=14=2V(H)+2V+2J+6(4v+2j)+2m(h)Brothera leana K(n)=12=2V(H)+2V+2J+4(2v+2j)+2v(h)Oncophorus crispifolius K(n)=14=2V(H)+2V+2J+6(4v+2j)+2m(h)Trachypus humilis K(n)=11=V(H)+2J+7(5v+2j)+m(h)Pseudospiridentopsis horrida K(n)=11=V(H)+2J+7(5v+2j)+m(h)Dolichomitra cymbifolia K(n)=11=V(H)+2V+J+6(4v+2j)+v(h)Dolichomitriopsis diversiformis K(n)=11=V(H)+2V+J+6(4v+2j)+m(h)Isothecium subdiversiforme K(n)=11=V(H)+2V+J+6(4v+2j)+m(h)Fauriella tenuis K(n)=11=V(H)+V+2J+6(5v+j)+m(h)Fabronia matsumurae K(n)=11=V(H)+V+J+7(5v+2j)+m(h)Schwetschkeopsis japonica K(n)=11=V(H)+2V+7(5v+2j)+m(h)Okamuraea brachydictyon K(n)=11=2V(H)+J+7(5v+2j)+m(h)O. hakoniensis K(n)=11=2V(H)+J+7(5v+2j)+m(h).
