dc.description.abstractElgon olive which is prized for durable structures and furniture has become rare and efforts to increase its population have been hampered by poor seed germination rates associated with dormancy. Search for alternative multiplication of the species is therefore important. The effect of rooting media and rooting hormone on regeneration potential of O. welwitschii were evaluated using leafy juvenile stem cuttings as an alternative multiplication method. A factorial experiment with 3 x 3 treatment combinations was established in a non-mist propagator in a complete randomized design with three replications. Factor one had three types of rooting media (fine river sand mixed with decomposed sawdust at 1:1 v/v, red clay subsoil and fine river sand) and factor two was rooting hormone indole-3- butyric acid (IBA) with three concentrations (0, 3000 and 6000 ppm). Data on rooting percentages and rooting variables were subjected to analysis of variance using SAS. The combination of fine sand mixed with decomposed sawdust media and cuttings treated with IBA at 6000 ppm provided the highest (p < 0.05) rooting of 92.3% and largest (p < 0.05) number of roots per cutting of 13.77. The combination of fine river sand mixed with decomposed sawdust and treated leafy juvenile stem cuttings with IBA at concentration of 6000 ppm is recommended as alternative technique for optimum production of O. welwitschii planting materials.en_US
