In vitro Propagation of Some Threatened Plant Species of India

To prevent extinction of threatened species, in vitro regeneration protocols for the propagation of six threatened species were standardized. The regenerated micro-shoots were ischolar_mained in nutrient medium supplemented with low concentrations of auxin. The well-developed plantlets were successfully established in field conditions, thus improving the probability of self-sustenance of the introduced populations. The success story of these six threatened species reaffirms the role of in vitro propagation in conserving plants facing the threat of extinction.
