  abstract = {{T}he architectural plasticity forms observed in trees is a result of meristem functioning, which generates new organs and branches, and adjusts growth processes in response to heterogeneous climatic adaptations that affect biomass allocation. {A}nalyzing this plasticity should enable the selection of adapted individuals for optimizing successful cropping systems. {M}ahogany tree ({K}haya senegalensis) is a rhythmically growing indigenous agroforestry tree that is heavily exploited for its multiple uses. {U}nderstanding its growth characteristics, as well as the complexity of its structure (randomness, rhythmicity, etc. of {M}ahogany tree), could facilitate its conservation and sustainable management. {T}his study aims to model the architecture and physiology of young mahogany trees based on field data using an organ-level structural-functional model called '{G}reen{L}ab', which is founded on source-sink relationships. {N}inety trees aged 6, 12, and 24 months were measured in the field. {D}evelopment was calculated using a dual-scale automaton based on the {M}onte {C}arlo process, while biomass production and its distribution to different plant organs (source and sink) were calibrated using {P}ressler's law using {M}arkov chains. {M}eristematic activity laws, combined with organ sinks ({D}: {D}emand), photosynthesis ({Q}: {S}upply), and organic series ({Q}/{D}: {T}rophic pressure), were employed to simulate individual architecture. {T}he results demonstrate that the model realistically and flexibly describes topological development and replicates biomass production and allocation processes for rhythmically growing trees. {T}his model will enable the identification of mahogany ideotypes suited for enhancing agroforestry cropping systems based on this species and several other threatened species. {T}hese findings introduce and thus lay the groundwork for a computational plant model tailored to the needs of agroforestry from a novel perspective, offering new avenues for agronomic and forestry applications in {W}est {A}frica and {C}ote d'{I}voire.},
