Cytological Studies on Some Chlorococcoid Green Algae

Abstract

In the present communication nine species belonging to eight Chlorococcalean genera and one belonging to Chlorosarcinaceae of Chlorosarcinales have been collected locally, isolated, and grown in cultures. All the algae have been subjected to karyological investigation. Their studies have shown the existence of cytological races in the genus Ankistrodesmus. Based on the chromosome number and karyological features the cytotaxonomic aspects of the algae have been discussed. It was concluded that taxonomic treatment on the basis of cytological data is possible only when a large number of species of each genus were undertaken and studied together.
