The Architectural Unit Setting up and Architectural Characteristics of Néré, <i>Parkia biglobosa</i>, Jack, R. Br. (Fabaceae)

Parkia biglobosa is a much-loved and over-exploited African savannah species for its socio-economic importance. Knowing taking into account architectural unit, which the basis diagnosing phenology, productivity tree health, could provide new perspective on sustainable management. The aim of this study to establish development in by retrospective analysis. To achieve objective, 390 individuals all sizes ranging from seedlings senescent trees were observed analysed under various soil climatic conditions Côte d’Ivoire. results showed that light plant but shading tolerant. It mixed vegetative axis plant, stem orthotropic* proximal part plagiotropic* (collapsing) distal young stage. then transitions an adult old stage with parts, trunk built up superimposing collapsed relay axes gradually straighten, branching sympodial*, growth defined sexuality terminal lateral. ontogeny takes place three phases: initiation establishment crown (young), flowering unity (adult) finally death secondary crown, duplication architecture series partial total reiterations (old). level organisation 5: phytomere, module or axis, unit reiterated complex.
