Direct and Indirect Organogensis in Medicinal Coleus (Coleus Forskohlii Briq.) - A Review

Coleus forskohlii Briq. is the only known natural source of forskolin. Micropropagation provides an opportunity to maintain type-to-type plant species and can produce a large number of plants from single clone. the maximum shoot proliferation (99.00 per cent) was noticed in BAP (2.00 mg l⁻¹). The best growth regulator treatment for rooting of coleus microshoots was IBA (0.2 mg l⁻¹) in half strength MS medium The growth regulator combination which produced highest percentage of callus induction from leaf bit was 2, 4, D (2.0 mg l⁻¹). For better rooting of callus derived microshoots, the ideal medium was found to be half strength MS medium supplemented with IBA (0.2 mg l⁻¹). Direct and indirect organogenesis of coleus were compiled and presented here under.
