Résumé : The detailed description of growth stages of useful plants followed by adequate codification facilitates communication between scientists and practicians if, for example, new findings of science have to be transferred to management procedures or if experiences made at one growing site have to be adapted to another. We describe the growth stages of the worldwide species of cacao trees (Theobroma sp.) to prepare the basis for production management, comparisons of epidemiological studies of disease, of growth patterns under different environmental factors and of genetically clone specific parameters. The codification follows the 'extended BBCH (BBCH, Biologische Bundesantalt, Bundessortenamt and CHemische Industrie, Germany) scale', a numerical system that differentiates between principal, secondary and tertiary growth stages. Each growth stage presented from seed germination to crown development and harvest is correlated with general management practices. This scale will be of great help to cacao growers and scientists around the world for better communication, more efficient planning of management practices and experiments.
