growth room at 14/10h continuous light and dark conditions at 25+2 °C. The cultures were monitored regularly and subcultures every 4 wks interval. For the inoculation of seeds, 65-70 days old green capsule was cut opened longitudinally and the seeds were scooped out with the help of forceps and spread over the surface of the germination media. The seeds were allowed to germinate and differentiate into protocorms and seedling development. Rhizome explant were excised from in vitro grown seedlings and cultured on the PGRs supplemented agar solidified MS medium. Rhizome segments produced directly multiple shoot buds (MSBs) via organogenesis and subcultured on the elongation media; and thereafter in rooting media for induction of well-developed root system. SPSs were produced at the base of some culture vessels and subcultured on elongation and rooting media respectively. 0.8% (w/v) agar solidified half strength MSO and auxin supplemented (IAA, IBA, NAA) nine different MS media were used for induction of strong and stout root system. The efficiency of the media in terms of enhancing the development of root system was assessed based on the increase in number and length of roots that developed within 30d of culture in rooting media. Rooted in vitro developed seedlings were taken out of the culture vessel and transferred to outside the culture room by successive phases of acclimatization. The seedlings of E. humulis were transferred to pots containing soil, sand, pit moss, saw dust and charcoal. Transplanted seedlings were watered regularly for about 2-3 months
