Studies on the regeneration in Macrostomum orthostylum (Braun) (Turbellaria: Macrostomida)
Abstract
The regeneration process was observed in the laboratory cultured macrostomid turbellarian, @iMacrostomum orthostylum@@ Recovery of cut portions was very fast at the anterior region as compared to the posterior region The average regeneration rate observed was 0.069 mm/day However, regeneration was not observed in the region anterior to the cerebral ganglion Information available on the regeneration in free-living Turbellaria indicates that acoelid turbellarians have limited power of regeneration (Ghild, 1907; Peebles 1913 and Keil 1929) In the case of alloeocoels and macrostomid, Ruhl (1927) has reported that the former are incapable of any regeneration and the latter whilst incapable of a sequal reproduction, can regenerate, particularly towards the tail portion Keeping in view the paucity of information on the regeneration in @iM orthostylum@@), the present studies was undertaken and results are reported
