Résumé : The present study was carried out to verify the statis tical relationships between the characteristic parameters in te rms of vegetative aerial architecture of the date palms for simulating realistic 3D models. The vegetal material was composed of two Tunisian varieties of Phoenix dactylifera L., “Barhi” and “Rochdi”. The observations ar e taken place in Gabes and on one pair of palms per main stem and offshoot for each cultivar. The an alysis of the characteristic dimens ions of the pinnae and rachis allo wed the determination of a minimum samp le. The geometrical analysis confirmed the exis tence of a strong correlation between rotation angles and radial angles. The architectural analysis of the two Tunisian cultivars re vealed that the distribution of characteri stic parameter values of pinnae was the outcome of a regionalized variable al ong the rachis. This statis tical study of relationships between the characteristic parameters in terms of vegetative aerial architecture of the two varieties allows executing a new measuremen t protocol for computing and si mulating realistic 3D models.
