Some New Records of Chromosome Numbers in Indian Charophyta

抄録

1. Karyological investigation has been made in five taxa of Charophytes, collected from paddy fields, ditches and ponds of Darbhanga (India)
2. n=35 and n=49 in the genus Chara while n=21 in the genus Nitella are new to science
3. n=7 and n=36 are also new chromosome counts for the taxa under investigation
4. n=7 and n=3 appear to be the ancestral basic chromosome numbers for Chara and Nitella respectively.
5. Acetocarmine technique, as devised by Godward (1948), has been employed throughout the course of investigations
