The vegetal material was composed of two Tunisian varieties of Phoenix dactylifera L., ＂Barhi＂ and ＂Rochdi＂. The observations are taken place in Gabes and on one pair of palms per main stem and offshoot for each cultivar. The analysis of the characteristic dimensions of the pinnae and rachis allowed the determination of a minimum sample. The geometrical analysis confirmed the existence of a strong correlation between rotation angles and radial angles. The architectural analysis of the two Tunisian cultivars revealed that the distribution of characteristic parameter values of pinnae was the outcome ofa regionalized variable along the rachis. This statistical study of relationships between the characteristic parameters in terms of vegetative aerial architecture of the two varieties allows executing a new measurement protocol for computing and simulating realistic 3D models.展开更多
