CHROMOSOME STUDY ON THE SUBMERGED MOSS COLLECTED FROM ANTARCTIC LAKES

Abstract: The submerged moss, which was found on lake beds in the Syowa Station area, East Antarctica was studied karyologically and taxonomically. The chromosome number of the moss showed to have n=23 and is expressed as n=22+m because it has a smallest chromosome with negative heteropycnosis. It m...

Description
Summary:Abstract: The submerged moss, which was found on lake beds in the Syowa Station area, East Antarctica was studied karyologically and taxonomically. The chromosome number of the moss showed to have n=23 and is expressed as n=22+m because it has a smallest chromosome with negative heteropycnosis. It may be appropriate to assign this moss to Leptobryum pyriforrne (HEDw.) WILS. judging from the chromosome number in addition to some morphological features such as sexuality and tubers. 1.
