Abstract

Polyzygus tuberosus Dalzell ex Walp. is a critically endangered and endemic species of South India that has received very little attention scientifically. The plant inhabits in a small patch of natural habitat in the field of Bangalore University, Jnanabharathi campus. In the present studies, the endemic and threatened status of this rare plant is revealed.Clonal propagation was succeeded from nodal explants inoculated on MS media supplemented with 0.3 mg/l BAP + 0.2 mg/l IBA for multiple shoot initiation. The nodal explants also induced multiple shoots on MS media supplemented with 0.5 mg/l BAP. The root and nodal explants induced callus on MS media supplemented with 2 mg/l NAA. Roots were initiated in half strength MS media supplemented with 0.3 mg/l IAA + 0.5 mg/l IBA. The hardened plants were reintroduced in its natural habitat and observed normal growth characters without any morphological changes.
