Summary
An in vitro Propagation Protocol for rapidly producing Hydrastis canadensis L., Goldenseal, plantlets from disk tissue of young leaves was developed. Leaf explants were inoculated on MS medium supplemented with various concentrations of NAA and TDZ for production of callus. Two-month-old calli were sub-cultured on MS media containing cytokinins (BA, kinetin, TDZ) in different concentrations for shoot initiation. The optimum level of callus induction and maintenance was in 5.3 muM NAA in combination with 2.2 muM of TDZ. Shoot multiplication was achieved on MS medium with 2.2 muM TDZ in combination with 0.5 muM NAA. The alkaloid profile of micropropagated plantlets was similar to the profile of the mother plants. These results suggest that our in vitro propagation protocol will produce a positive impact in the conservation of H. canadensis.
