Freycinetia is usually propagated by shoot tip and stem or nodal cuttings. It is a slow growing plant and takes time to produce side shoots and laterals that can be used for propagation. To modify certain practices and increase the efficiency of mass propagating Freycinetia, a rooting experiment using tip and basal cuttings of the most common species, F. multiflora were conducted. Findings showed that basal stem cuttings produced more extensive root system, with an average of 6.17 roots, than tip cuttings (3.3 roots). Treatment with 100 ppm naphthalene acetic acid (NAA) or indole butyric acid (IBA) for three hours improved the rooting response. One hundred percent rooting was obtained from cuttings treated with 100ppm NAA, and 91.67% rooting from 100ppm IBA. Basal stem cuttings benefited from auxin treatment only if the concentration used was 200ppm. Tip cuttings, 8-10 cm, were good sources of planting materials, compared to 5-cm cuttings. Dipping them in 100 ppm IBA for 30 minutes improved the rooting of tip cuttings. Position of nodal cuttings slightly influenced rooting. Rooting was best (85.71%) from stem cuttings derived from the third 8-cm section from the tip.
