Abstract

Abstract:

In this paper the chromosome number of 6 mosses species are reported.

The materials used for investigation were taken from immature capsules. Meiosis

in spore mother cells were observed, and the results are as follows: Brachythecium

plumosum, n=15. Entodon obtusatus, n = 11. E.okamurae, n = 11.

Anoectangium aestivum, n= 13. Bryum argenteum, n= 10. Eurhynchium

eustegium, n = 20+ 2m. The chromosome number of the former three species are re-

ported for the first time.

Key words: Chromosome number, Brachythecium plumosum, Entodon obtusatus, Entodon okamurae, Anoectangium aestivum, Bryum argenteum, Eurhynchium eustegium.
