Effects of growth hormones, rooting media and leaf size on juvenile stem cuttings of Buchholzia coriacea were investigated. Two hundred sixteen single node were obtained from two month old seedlings . Half had their leaves reduced, while the remaining retained original size. Cuttings treated with indole butyric acid (IBA), naphthalene acetic (NAA) a combination hormones (IBA/NAA), at 0, 50, 100 150 mg/l planted in three media-topsoil, riversand sawdust giving factorial design. assessed for percentage survival, number roots, length longest root total length. ANOVA was carried out data collected LSD 5% probability level used to compare significantly different means. Survival 96.3% recorded. The highest mean values 3.8 cm 12.5 recorded topsoil. Control roots - 4.8. Leaf highly significant effect as whole rooted better than half leaves. Single is amenable cloning or without auxin treatment.
