EFFECT OF CYTOKININS ON <em>IN</em> <em>VITRO</em> PROPAGATION OF <em>UAPACA</em> <em>KIRKIANA</em>

Abstract

The effect of five different types of cytokinins, namely N⁶-benzyladenine (BA), kinetin, N⁶-(2- isopentenyl) adenine (2iP), thidiazuron (TDZ) and zeatin on in vitro propagation of Uapaca kirkianavtas studied using woody plant medium (WPM). Good quality shoots (with a mean of 3.4 shoots per explant) were regenerated on the WPM supplemented with 0.5(1 M BA. The suitability of different cytokinins for in vitro propagation of Uapaca kirkiana was established in the order of BA>TDZ>2iP>kinetin>zeatin. On TDZsupplemented medium, stunted shoots with comparatively thicker leaves were regenerated. Shoots produced on WPM supplemented with BA rooted easily. In vitro regenerated plantlets were established under ex vitro conditions.
