The aim of the present work was to evaluate the regeneration of Gilbertiodendron dewevrei in the Botanical garden of the Faculty of Science, University of Kisangani/DR Congo. 1.439 individuals were listed and gathered in various classes of size, diameter of stem and distribution around the carrying foot. 33 years after the establishment of this botanical garden, Gilbertiodendron dewevrei was transformed into a forest species. Indeed, it found ecological conditions similar to those of its medium of origin and which favor its optimal ex situ development. The individuals having the size ≤ 50 cm, are the most represented with 1055 individuals (73,3%) and numbers it individuals having a diameter ≤ 10 cm are higher with 1358 individuals (94,3%). The data on the carrying foot showed a good regeneration of the species. The number of individuals falls when classes progress in the ascending order. It is thus desirable that studies are regularly carried out on the species headlights of the botanical garden for a permanent follow-up of the evolution of their florula.

Abstract: (french)
Le présent travail avait pour but d’évaluer la régénération de Gilbertiodendron dewevrei au Jardin botanique de la Faculté des Sciences de l’Université de Kisangani/RD Congo. 1.439 individus ont été recensés et regroupés en différentes classes de taille, de diamètre de tige et de distribution autour du pied porteur. 33 ans après l’implantation de ce jardin botanique, Gilbertiodendron dewevrei s’est transformé en une espèce de la forêt. En effet, il a trouvé des conditions écologiques similaires à celles de son milieu d’origine et qui sont favorables à son développement optimal ex situ. Les individus ayant la taille ≤ à 50 cm, sont plus représentés avec 1055 individus (73,3%) et le nombre d’individus ayant un diamètre ≤ à 10 cm sont plus élevés avec 1358 individus (94,3%). Les données sur le pied porteur ont montré une bonne régénération de l’espèce. Le nombre d’individus diminue lorsque les classes progressent dans l’ordre croissant. Il est donc souhaitable que des études soient régulièrement réalisées sur les espèces phares du jardin botanique en vue d’un suivi permanent de l’évolution de leur florule.
