“…Local production and consumption of resources, which are affected by the environment and status of particular structural units, control the growth of the three-dimensional structure. Source sink phenomena have been modelled by considering unit to unit interactions (Balandier et al, 2000), accumulating information along the pathways from root tip to shoot tip (de Reffye et al, 1997) or solving partial differential equations (Deleuze and Houllier, 1997;Palovaara, 2003). How the intensive calculations required by the sink-source approach are best implemented in the three-dimensional plant structure is still unknown.…”

“…Lindenmayer systems or L systems (Prusinkiewicz and Hanan, 1989), are the most widely used method to treat plant architecture although other formalisms also exist (e.g. de Reffye et al, 1997;Godin et al, 1999). L systems were invented by Aristid Lindenmayer (1968Lindenmayer ( , 1971 and were initially meant to describe the development of multicellular organisms.…”

“…The methods for plant architecture (Prusinkiewicz and Lindenmayer, 1990;de Reffye et al, 1997;Godin et al, 1999) offer means for treating tree architecture in a formal, and therefore comparable way. However, these formalisms have so far not matched the capabilities of general programming languages to deal with diverse programming tasks (e.g.…”

LIGNUM is a functional-structural tree model that represents coniferous and broad-leaved trees with modelling units corresponding to the real structure of trees. The units are tree segments, axes, branching points and buds. Metabolic processes are explicitly related to the structural units in which they take place. This paper enhances the modelling capabilities of LIGNUM with the possibility to formally describe the architectural development of trees with Lindenmayer systems. This is achieved by presenting an algorithm to convert tree structures generated by Lindenmayer systems to the LIGNUM representation of trees with feedback of results of events or processes from LIGNUM to Lindenmayer system. We then give two example applications that model the development of Scots pine (Pinus sylvestris L.) and the dwarf shrub bearberry (Arctostaphylos uva-ursi L.). Finally we discuss our approach and its consequences for the future development of LIGNUM.

“…De Reffye et al (41) presentan una modificación al modelo AMAP de simulación de arquitectura, para incluir el efecto del transporte del agua. Asumen a la planta como un conjunto de cañerías interconectadas, que transportan agua desde las raíces a las hojas, en un flujo que obedece a las leyes físicas de fluido por diferencia de potenciales hídricos.…”

SUMMARYThe advances in trees and plants architecture and their physiology analysis, and on the other hand the advances in computer sciences, have permitted the development of 3D structural plant models. The basic modeling units are usually leaves internodes, buds and fruits or flowers. The state of the art is presented in this kind of models, as are also the functional-structural models that are integration between structural models and physiological ones. Some tools and concepts used in this kind of modeling, as L-Systems, automata cellular, stochastic modeling, are also presented. The future trend will be a stronger development of these models, including variations due to environment and management, in order to support the decision taking.Key words: functional-structural models, crown, L-Systems, fractal theory. RESUMENLos avances en el análisis de la arquitectura o estructura de los árboles y plantas y su fisiología y, por otra parte, los avances en el área de la computación, han permitido desarrollar modelos estructurales tridimensionales del desarrollo de vegetales, usando generalmente como unidad mínima a modelar las hojas, internudos, yemas y frutos. Se presenta el estado del arte en este tipo de modelos, así como los modelos funcionales-estructurales, que integran modelos estructurales con modelos de procesos fisiológicos en la planta. Algunas herramientas usadas para este tipo de modelación, tales como Sistemas L, concepto de autómata celular, modelación estocástica, son presentadas. Se observa que la tendencia a futuro será desarrollar más este tipo de modelos integrados, incluyendo variaciones debido al ambiente y manejo, de manera de que apoyen la toma de decisiones.

“…Generic tools have already been developed to visualize plant architecture in 3-dimensions ( [4,30]), to model the growth of plant architecture, e.g. ( [20,25,5,21]), to measure plant architecture ( [9,14,33]), and to explore and to analyze the plant [10]. This paper introduces a new tool for the comparison of plant architectures.…”
