In Vitro Propagation Of Endangered Lippia Filifolia Mart. And Schauer Ex Schauer

This work describes an efficient micropropagation protocol of Lippia filifolia. Nodal segments cultivation in MS medium supplemented with 6-benzylaminopurine (4.5 mu M)/ alpha -naphthaleneacetic acid (NAA; 54 nM) induced multiple shoots (in average 27 shoots per explant). Elongated shoots were rooted with NAA (0.11 mu M) and they maintained ploidy level of the in vitro produced explants. The basic chromosome number were 2n=2x=24. Regenerated rooted shoots were successfully acclimatized under shading house conditions. This is the first report involving the establishment of a protocol for shoot multiplication and rooting for endangered L. filifolia, contributing for germplasm preservation of this species.
