Abstract: | This report describes in vitro shoot induction and plant regeneration from mature nodal explants of Vitex trifolia L. on Murashige and Skoog (MS) medium fortified with benzylaminopurine (BAP), kinetin (KN), thidiazuron (TDZ), adenine (ADE),
and 2-isopentenyladenine (2-iP) (0.25 – 10.0 μM). Multiple shoots differentiated directly without callus mediation within
3 weeks when explants were cultured on medium supplemented with cytokinins. The maximum number of shoots (9 shoots per explant)
was developed on a medium supplemented with 5.0 μM BAP. Shoot cultures was established repeatedly subculturing the original
nodal explant on the same medium. Rooting of shoots was achieved on half strength MS medium supplemented with 0.5 μM naphthaleneacetic
acid (NAA). Rooted plantlets transferred to pots containing autoclaved soil and vermiculite mixture (1:1) showed 90 % survival
when transferred to outdoor. |
