ABSTRACT: A plant regeneration protocol via adventitious shoot organogenesis from internode explants of Paederia foetida (Skunk vine) is reported here for the first time. Three explants (leaf, mature internode and internode derived from axenic shoot cultures) were tested for shoot organogenesis. Leaf explants failed to induce adventitious shoots whereas axenic internode explant was found to be superior to mature internode explants for the induction of adventitious shoots. Axenic internode explants cultured on MS medium supplemented with 3.0 mg/l BAP showed maximum (86.7 %; 10.4 shoots per explant) adventitious shoot organogenesis. The regenerated shoots were best rooted (90 %; 14 roots per shoot) on half-strength MS medium. Eighty percent of the rooted shoots were successfully acclimatized in soil: sand (1:1) mixture. All these acclimatized plants were successfully transferred to larger pots containing garden soil and subsequently established in the field.
