Premires donnes sur l'architecture compare des systmes racinaires et caulinaires

Since 1970, the architectural analysis of woody plants has given much information about structural and functional organization of tree crowns, their development, and reiteration patterns. In this study, we have extended this method to tree root systems. We describe the whole architecture of three species and we compare their root system and crown architectural patterns. Key words: architecture, tree, root system, crown, whole plant.
