In-vitro micropropagation and comparative study on antimicrobial activity of micropropagated and naturally growing plants of Syzygium cumini

Syzygium cumini is an important medicinal plant. A micropropagation protocol was developed from nodal explants of eight months old plantlets of S. cumini. Shooting was induced on MS medium supplemented with combinations of BAP and IBA. The shoots were rooted in half strength MS medium supplemented with IBA and sucrose. Acclimatization was successful and plantlets established in the field showed good survival response. Antimicrobial activity was carried out against coliforms (directly isolated) and mixed culture (mixture of pure cultures of coliform group of bacteria) with respect to in-vivo and in-vitro leaf extracts of S.cumini.
