types of explants was tested in view of elaborating a micropropagation technique for this
species, to provide in vitro regenerants for repopulating native habitats of R. rosea, where it
has extinguished or is endangered. It was ascertained that the most efficient variants of MS
medium to provide neoplantlets from shoot nodes and apices are: N (2.0 mg l-1 NAA),
followed by hormone free MS, then KN (1 mg l-1 Kin+ 0.5 mg l-1 NAA), and AZ (0.2 mg l-1 …
