<p><em>Haematostaphis barteri is a highly valued wild species of </em><em>socio-economic interest that is under multifaceted pressure. Indeed, excessive use of this plant leads to a repressive dynamic in its population. The objective of this work is to evaluate the aptitude of </em><em>Haematostaphis barteri for air layering. The layering technique used consists of girdling the branch in order to remove the bark over a length of 6 or 7cm until the wood appears. Then, the cambium is thoroughly scraped and the phloem is thoroughly removed. </em><em>Three trials were conducted. The first and second were carried out in august 2023, they consisted of determining the favorable period for air layering by </em><em>quantifying carbohydrates on the mother plants of the species during the year(trial 1). For experiment two, the substrates used consisted of </em><em>back soil; the black soil/sawdust mixture (40/60%); the spent grain of traditional beer and the foam. the experimental unit consisted of 10 layers. That is, a total of 120 layers(10 x 4 x 3). The experimental devise used was a completely randomiwed block for the first, two trials. The last experiment was carriedout in june 2024. Thus, using the tailor’s tape, </em><em>three ra</em><em>nges of branch diameter [2-4</em><em>[</em><em>cm; [4-6</em><em>[cm</em><em>; [6-8</em><em> [cm</em> <em>were examined in the best substrate of the previous trial. That is, a total of 180 layers (10 x 3 x 2 x 3) were placed. The experiment design used is a Split-plot with 3 repetitions. The results of this study show that</em> <em>the quantification of sugars shows that the favorable period for conducting aerial layering of the species is the beginning of the rainy season.</em> <em>Haematostaphis barteri has a good aptitude for air layering. The type of substrate, the diameters of the branches and the aluminium foil have an influence on the rooting rate. The black earth/sawdust mixture with a rate of (63.33±15.27%) is numerically the best rooting substrate and the diameters </em><em>[4-6]cm and [6-8]</em><em>cm presented promising results for the same rooting parameter in this species. The aluminium foil improved and protected the sheaths against light rays. These tested parameters are important in developing a domestication strategy for this species.</em></p>
