TITLE :STUDIES ON M-CHROMOSOME IN LIVERWORTS FROM WEST HIMALAYAN REGION
ABSTRACT: Cytological studies were made in two liverworts collected from Lal tibba, Mussoorie and Glen, Shimla belonging to Western Himalayan region. The chromosome number was reported to be n=9 in both the liverworts i.e. Conocephalum conicum and Plagiochasma articulatum. The presence of an m- chromosome (8+m) has been reported in both the plants, which is in accordance with the earlier reports. This dissociation is probably due to small size of the chromosomes permitting few or no chiasmata. It is nearly one-tenth or less the size of the largest chromosome.
