Abstract
A highly efficient protocol for the induction of adventitious shoots from young internode and root explants of a semiparasitic medicinal herb Monochasma savatieri Franch ex Maxim was developed. MS basal medium supplemented with 5 µM thidiazuron (TDZ) induced 32 adventitious shoots/explant, which was double the number obtained using the same concentration of 6-benzyladenine (BA). Hyperhydric shoots were observed when 10 µM of any cytokinin was added to MS media. Use of any cytokinin at 2.5 µM produced an average of 14–21 adventitious shoots/root explant. Shoots formed roots in vitro more effectively than α-naphthaleneacetic acid when indole-3-butyric acid and indole-3-acetic acid were used at 1.0 µM. Two-month-old rooted plantlets were transplanted to vermiculite and 70% survived after 4 months.
