Abstract
The objective of this study was to determine the influence of branch type on the cutting ability of eight kola clones (Cola nitida). To this end, the clones were tested in a split-plot experimental design with the factors studied being the clone and the nature of the branch. After seven weeks of experimentation, survival rates were evaluated for each clone and for each type of cutting. The results showed that the clones were significantly different for the survival rates obtained (p = 0.00). The terminal branches were more suitable for cutting (70.62% survival) than the sub-terminal branches (33.95%). The age of cutting therefore influenced the success of cutting in the clones studied. At the end this work, we note that clones 305, 323, 330, 903A3 and 911A2 are promising for kola tree cutting from terminal branch and that clone 910A1 cut easily with both terminal and sub-terminal branch.
Highlights
The kola tree (Cola nitida) belongs to the family of Malvaceae
In clones 910A1, 911A2, 910A2 and 330, stable survival was initiated 7 days after the other clones, either on day 28 (Figure 3). Similar trends to those obtained for sub-terminal twigs observed
Clone 323 marked the longest time of stable survival of cuttings (14-42 days after transplantation) and clone 903A3 marked the longest phase of decreasing survival (7-35 days after transplantation)
Summary
The kola tree (Cola nitida) belongs to the family of Malvaceae. It is a tree native to the warm and humid regions of tropical West Africa [1]. 140 species of kola tree have been counted [2] of which two are cultivated for their nuts [3] and their multiple uses [4]. These are Cola nitida and Cola acuminata. Kola nuts are known for their high caffeine content, between 1.84 and 2.56% [5]. As a result, they are widely used in the food industry for the manufacture of energy drinks [6]. The cola nut plays an important role in African society for cultural and customary rituals such as births and weddings [11]
