| Abstract | The ecological adaptation of shea butter trees was assessed based on their dendrometric and production traits in four shea butter tree parks occurring in different climatic zones of Benin. A total of 99 rectangular plots of 50 × 30 m were established within the four parks according to a random sampling scheme. In each plot, all trees with a diameter at breast height (dbh) >10 cm were inventoried and measured for stem and crown diameters, and total height. The production of 120 productive shea butter trees was quantified. Collected data were used to compute structural parameters for each park. Moreover, stem diameter and height structures of the trees were established. Principal component analysis was performed on the dendrometric variables, and the first three components were correlated with the climatic parameters. Results revealed significant differences between parks in most of the dendrometric and production parameters of shea butter trees. For all the four parks, stem diameter and height structures present a Gaussian shape with left dissymmetry. In the Guinean zone, shea butter trees develop large crowns but produce little quantities of fruits, whereas in the Sudanian regions, the opposite trend was observed. Resume L’adaptation ecologique des arbres a karite a eteevaluee en en considerant leurs caracteristiques dendrometriques et de production dans quatre dans quatre parcs a karite situes dans des zones climatiques differentes au Benin. Au total, 99 placeaux rectangulaires de 50 × 30 m furent etablies dans les quatre parcs selon un schema d’echantillonnage aleatoire. Dans chaque parcelle, tous les arbres dont le diametre a 1,3 m du sol est superieur a 10 cm ont ete inventories et mesures en diametre du tronc et de la couronne ainsi qu'en hauteur totale. On a aussi quantifie la production de 120 arbres a karite productifs. Les donnees collectees ont permis de calculer des parametres structuraux pour chaque parc. De plus, on a etabli les structures en diametre et en hauteur des d’arbres. Une Analyse en composantes principales fut realisee sur les variables dendrometriques, et les trois premieres composantes furent mises en relation avec les parametres climatiques. Les resultats obtenus ont montre des differences significatives entre parcs pour la plupart des parametres dendrometriques et de production des arbres a karite. Pour les quatre parcs, les structures en diametre et en hauteur des arbres presentent une courbe de Gauss avec une dissymetrie gauche. Dans la zone guineenne, les arbres a karite developpent de larges couronnes mais produisent de petites quantites de fruits alors que dans les regions soudaniennes, on observe une tendance inverse. |
