Okunlola A Ibironke

An experiment was conducted in the nursery, the department of Crop, Soil and Pest management the Federal University of Technology, Akure, on stimulation of rooting of three ornamentals; Euphorbia milii, Adenium obesium, and Murraya paniculata, (Christ thorn, Desert rose and Murraya respectively) using some rooting substances; Indole-3-butyric acid (IBA), Top soil, Coconut water and Tetracycline from July to September, 2013. The experiment was laid out in a Completely Randomized Design (CRD) and replicated four times. Data were collected on number of branches, the number of leaves per cutting, root weight, number of roots and length of roots. The results from the study showed that each of the treatment had significance (P<0.05) with respect to a specific plant. Tetracycline was found the best for rooting Christ thorn cuttings. Indole-3-Butyric Acid (IBA) was found the best for rooting Roses cuttings. Coconut water treatment was found the best for rooting Muraya cuttings. The different treatments produced significant variation while there was no significant variation among the three different plant cuttings, but in the interaction between the plant cuttings of the different treatments.
