Abstract
Phytohormones have been found to be a reliable growth enhancer. This study therefore investigated the potentials of natural plant hormones on the rooting and survival ability of the species. The cuttings of T. africana were set in sixteen germination trays containing sterilized river with 3 replicates. The experiment had fifteen treatments and one control and was laid out in a Completely Randomized Design (CRD). Data were collected weekly for number of leaves per cuttings; shoot height (cm), root length, number of roots, shoot collar diameter and survival percentage (%). Data were analyzed using Analysis of Variance (ANOVA) and Least Significant Difference was used to separate the means. The result show significant differences in number of leaves and root length (P<0.05). However, there were no significant differences (P>0.05) in survival percentage, number of root and collar diameter. The highest Mean shoot height (11.03±2.03 cm), number of roots (5.0±0.65), Survival percentage (79.7±5.6 %) and Root length (0.98±0.07) were recorded for T10 (75% of Moringa leaf extract + 50% of orange juice) while control treatment (T10) had the least values in all the growth variables. It is therefore established from the study that Moringa leaf extract and Orange juice had significant influence on the growth variables of T. africana stem cuttings
