ABSTRACT:
Leaf explants of Scoparia dulcis L. gave rise to multiple shoots when cultured on MS medium supplemented with different concentrations of TDZ and IAA. The highest rate of shoot multiplication was obtained in MS medium containing 4.0 µM TDZ and 1.0 µM IAA (26.6 ± 0.98). Differentiated shoot buds elongated to 5.8 cm in 21 days in 9 µM KIN amended medium. The regenerated shoots were rooted on half-strength MS basal medium with different concentrations of IBA and IAA. The maximum number of roots was achieved on the medium containing 2.8 µM IBA. In vitro regenerated plantlets were transferred to plastic pots containing coco peat as a potting mix and were thereafter successfully established under ex vitro conditions. The survival percentage of transplanted plantlets was 90.6%.
