Résumé : Since Hallé & Oldeman (1970), plant architecture concepts are used when studying plant form and ontogeny. Using the identification of several morphological criteria and considering the plant as a whole, from germination to death, architectural analysis is essentially a detailed, multilevel, comprehensive and dynamic approach to plant development. After twenty years, this approach was completed by appropriate quantitative methods of mathematical analyses and modeling approaches (de Reffye et al. 1991). Recent researches in this field have greatly increased our understanding of plant structure and development and have led to the establishment of a real conceptual and methodological framework for plant form and structure analysis and representation (Godin & Caraglio 1998; Guédon et al. 2001; Barczi et al. 2008; Mathieu et al. 2009). In 2007, Barthélémy & Caraglio published a large review on plant architecture which provides generic terminology and the concepts for plant architecture interpretation. The current poster aims to briefly illustrate some applications of the main concepts like architectural unit, reiteration process, morphogenetical gradients and physiological age of meristems. Specific data and results are given to provide reproducible examples on other species. Theses concepts are also useful tools for sampling plant structure in regards to ecophysiological questions on leaf physiology (Roggy et al. 2005; Coste et al. 2009; Leroy et al. 2009) and wood anatomy and hydraulic (Cochard et al. 2005). Finally, we address some present questions on phenotypic plasticity (Stecconi et al. 2010; Charles-dominique 2010; Taugourdeau et al, 2011), forestry (Rutishauser et al, 2010), agronomy (Rey et al. 2008) and paleobotany (Meyer-Berthaud et al. 2010) and particularly how architectural features can become relevant original traits for ecological and evolutionary studies.
