A cost-effective and efficient protocol has been described in the present work for large scale and rapid in vitro propagation of a valuable medicinal herb Bacopa monnieri (L.) by shoot bud proliferation on internodal segments isolated from field grown mature plants. This shooting was achieved on low concentration of cytokinin with BAP 1.0 mg/l and Kn 0.5 mg/l within 3 weeks of inoculation contrary to earlier reports where auxin is also used in combination with cytokinin. Normally internodes gives rise to a clump of shoots (18 shoots). On an average within a period of three subcultures the internode explant generated 324 shoots thereby improving the economics of the cost of the plants produced and time required. For rooting this is a first report of its growth in a liquid culture. The regenerated plants resemble the mother plants in the general habitat without any morphological variation. This paper reports a very simple, reproducible procedure for in vitro propagation of Bacopa monnieri (L.) that can be used to form a foundation stock of elite plant material for large-scale cultivation.
