LIGNUM: A Tree Model Based on Simple Structural Units
TL;DR: The model LIGNUM, which describes the three dimensional structure of the tree crown and defines the growth in terms of the metabolism taking place in these units, has been parametrized for young Scots pine (Pinus sylaestris L.) trees.
Journal ArticleDOI
Components of functional-structural tree models

TL;DR: In this article, a synthese des approches realizedes dans le cadre de la modelisation fonctionnelle et structurale des arbres (FSM) is presented.
Journal ArticleDOI
LIGNUM: a model combining the structure and the functioning of trees
TL;DR: The model LIGNUM, which describes the three-dimensional structure of the tree crown and derives growth in terms of the metabolism taking place in these units, has been parametrized for young Scots pines.
Journal ArticleDOI
Application of the Functional-Structural Tree Model LIGNUM to Sugar Maple Saplings (Acer saccharum Marsh) Growing in Forest Gaps
TL;DR: This version of LIGNUM modified for use with broad-leaf, deciduous trees and parameterized for sugar maple, yields good simulations of growth and form in saplings from different forest gap environments.
Journal ArticleDOI
Toward extension of a single tree functional–structural model of Scots pine to stand level: effect of the canopy of randomly distributed, identical trees on development of tree structure
TL;DR: This work describes here how a 'shoot-based' individual tree model, LIGNUM of Scots pine has been applied to a group of identical trees (forest) and produced results that are comparable with observations made in real Scots pine trees and tree stands in Finland.
