Ceiba pentandra (Linn.) Gaertn. commonly known as kapok, is an important tree species for agroforestry systems since it has straight bole with acute branches, which permits sufficient sunlight to fall on ground for the growth of under storey crops. Investigations were undertaken to study the effect of root inducing hormones viz., IBA, IAA and NAA on the rooting and growth of cuttings of Ceiba pentandra. 1000 - 5000 ppm in solutions and 1-5 per cent in powder formulation concentrations of IBA, IAA and NAA compounds were tried for rooting and growth of cuttings. Among root inducing hormones, IBA 3000 ppm in solution and 3 per cent powder formulation showed significant effect on sprouting percentage, percentage rooting, average number of roots and root length. The relevance of the findings for the rapid mass clonal multiplication of economically important tree species has been discussed.
