The geometrical and topological organisation of these components defines the plant architecture. Before the early 1970 s botanical drawings were the only means to represent plant architecture. In the past two decades high-performance computers have become available for plant growth analysis and simulation triggering the development of various formal representations and notations of plant architecture strings of characters axial trees tree graphs multiscale graphs linked lists of records object-oriented representations matrices fractals sets of digitised points etc. . In this paper we review the main representations of plant architecture and make explicit their common structure and discrepancies. The apparent heterogeneity of these representations makes it difficult to collect plant architecture information in a generic format to allow multiple uses. However the collection of plant architecture data is an increasingly important issue which is also particularly time-consuming. At the end of this review we suggest that a task of primary importance for the plant-modelling community is to define common data formats and tools in order to create standard plant architecture database systems that may be shared by research teams. plant architecture geometry topology scales of representation encoding Résumé - Representation et codage de l architecture des plantes. Une plante est constituée d entités ayant des types et des formes variés. L organisation géométrique et topologique de ses entités définit l architecture de la plante . Avant le début des années 70 la seule faẹon de représenter l architecture des plantes était de faire des dessins
