OBJECTIVE To develop an improved protocol for micropropagation of ethnomedicinally important Scoparia dulcis (S. dulcis) L. METHODS Explants were inoculated on MS basal medium supplemented with kinetin and 6-benzylaminopurine for shoot bud induction. To enhance the shoot induction, various auxins like 3-indoleacetic acid or 3-indolebutyric acid or α-naphthylacetic acid were tested along with ...
