Abstract (2. Language): 
The present survey aims at establishing the influence of the dynamic of two arborescent Legumes trees of the Mimosaceae family (Albizia adiathifolia and Albizia zygia) on the woody forest, their evolution during the reconstitution of post-cultural flora. It was conducted at Oumé (West-Center of Côte d’Ivoire) in semi deciduous forest zone. The main objective is to highlight the influence of Albizia adianthifolia and Albizia zygia two legumes tree, on the other woody forest species on the basis of the correlations between biological parameters (growth in height, growth in thickness) resulting of interspecific competition (Albizia-other woody forest species) in order to put it to use in the programs of forest regeneration. Flora inventories and measurements done in 45 gradual age plots (5 to 53 years) showed that at the youthful stadium (0 to 10 years), the growth in thickness of the woody forest is influenced by the one of the two arborescent Leguminous trees (Albizia adianthifolia and Albizia zygia). On the other hand, the influence of the height growth of the arborescent leguminous trees on the one of the woody forest is discernible between 0 and 25 years. Beyond of 25 years the woody forests are progressively higher than the Albizias and finish by imposing themselves after 65 years.
