| Abstract: | Rhizomatous buds of Kaempferia galanga and K.
rotunda induced microshoots when cultured
on Murashige and Skoog (MS) medium supplemented with plant growth regulators.
Multiple shoots were induced on MS medium containing 5.70  M IAA alone and a combination of 0.57 M IAA plus 4.65 M Kn in case of K. galanga. Whereas, the medium
supplemented with 2.69 M NAA plus 2.22 M BAP was the best for K.
rotunda. Further, subculture of the microshoots gave more multiple shoots
(13) on medium containing 4.44 M BAP in K. galanga and (9)
on the 2.69 M
NAA and
2.22 M BAP in K. rotunda. Induction of callus was observed in K. galanga on the medium supplemented
with 2.85 M IAA. Microshoots were regenerated from the callus on 2.69 M NAA and 2.22 M BAP enriched medium.
Microrhizome formation was observed within one month of incubation of
microshoot cultures (~4 month old, following 4 passages) in the medium
supplemented with 6-9% sucrose with either 22.2 M BAP or 23.25 M Kn. These microrhizomes
produced shoots when transferred to fresh microshoot induction medium within
2-3 weeks of incubation. The microshoots produced roots irrespective of their
method of regeneration. Plantlets transplanted to pots grew to mature plants
after 3 months of transfer and showed 80-90% survival. |
