Response of shooting hormones on the stem cuttings of Khaya ivorensis A. Chev.

Abstract

The study investigated the effect of different hormones on the stem cuttings of Khaya ivorensis. The experiment was made up of five treatments which are (treatment one) Benzyl Amino Purine at 0.01gm/m level of concentration, (treatment two) kinetin at 0.01gm/m level of concentration, (treatment three) combination of both kinetin and benzyl amino purine, (treatment four) coconut water, and (treatment five) distilled water. The experimental design was completely randomized design (CRD). The result obtained showed that kinetin at 0.01gm/m level of concentration had the best performance of shoot height (13.04cm) while the least was the distilled water (4.27cm), combination of both kinetin and benzyl amino purine (6.54) gave the best performance in terms of number of leaves and the least was distilled water (4.68). For stem diameter, kinetin had the best performance (0.34mm) while the least was coconut water and distilled water (0.26mm). Based on the result of this study, it is concluded that kinetin is the best hormone for raising Khaya ivorensis and further study is recommended to be carried out at higher concentrations to determine the best concentration of hormones for optimal growth.
