The aim of the present study was to evaluate the influence of the cuttings site and the age/state of the branch on the cuttings of the cola tree in the optics of its domestication (ex situ conservation). To this end, plageotropic and orthotropic branches having each one three nodes, equipped well were divided like cuttings and were placed in polyethylene bags containing a substrate based on a mixture of black cotton soil, chicken dejection and sawdusts broken up well. The results of this study indicate that 70 days after cuttings, on average 73% of the cuttings began again. However, after 90 days, the rate of survival recorded was 58.4%. Compared to the site of the cuttings, the best results were obtained with the cuttings taken on the orthotropic branches compared to the plageotropic branches. Compared to the state of the branch, the best results were obtained with the cuttings taken on the semi-ripened branches. Thus, the site of the cuttings and the age/state of the branch are parameters which condition the success of the cuttings of wild fruit trees such as the cola tree. It would be thus desirable that a study is carried out in order to evaluate the influence of the phyto-hormones on the cuttings of semi-ripened orthotropic branches.

Abstract: (french)
La présente étude avait pour but d’évaluer l’influence de l’emplacement des boutures et l’âge/état du rameau sur le bouturage du kolatier dans l’optique de sa domestication et de sa conservation ex situ. A cet effet, des rameaux plagéotropes et orthotropes ayant chacun trois nœuds, bien habillés ont été sectionnés comme boutures et placés dans des sachets en polyéthylène contenant un substrat à base d’un mélange de terre noire, de sciure de bois bien décomposée et de fientes de poules. Les résultats de cette étude indiquent que 70 jours après bouturage, en moyenne 73% des boutures ont repris. Cependant, après 90 jours, le taux de survie enregistré a été de 58,4%. Par rapport à l’emplacement des boutures, les meilleurs résultats ont été obtenus avec les boutures prélevées sur les rameaux orthotropes comparativement aux rameaux plagéotropes. Par rapport à l’état du rameau, les meilleurs résultats ont été obtenus avec les boutures prélevées sur les rameaux semi-aoûtés. Ainsi, l’emplacement des boutures et l’âge/état du rameau sont des paramètres qui conditionnent le succès du bouturage des arbres fruitiers sauvages tel que le kolatier. Il serait donc souhaitable qu’une étude plus approfondie soit réalisée en vue d’évaluer l’influence des phytohormones sur le bouturage de rameaux orthotropes semi-aoûtés.
