To prevent extinction of threatened species, in vitro regeneration protocols for the propagation of six threatened species were standardized. The regenerated micro-shoots were rooted 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.
Musa nagalandiana S. Dey & Gogoi, a new species of Musa sect. Musa, is described and illustrated from Zunheboto district, Nagaland, India based on morphological characteristics observed in the field. The new species is rare in the wild and found in tropical semi‐evergreen forest on the bank of the river Doyang, in Zunheboto district of Nagaland. A key to M. nagalandiana and related taxa is provided.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
