Abstract: | Summary A protocol has been developed that leads to the development of complete plantlets of Coleus forskohlii within 35–40 d by culturing stem tip explants in MS medium containing 0.57 μM indole-3-acetic acid and 0.46 μM kinetin through direct multiplication at the rate of 12.5 shoots per explant. About 100% shoots rooted and micropropagated plants were successfully established in soil after hardening with a high survival rate. The significance of the present micropropagation protocol of C. forskohlii is the formulation of growth regulators which effected very fast multiplication of the plant (time reduced to one-third of the hitherto known methods). |
