CONTENTS Functional-structural tree models The Model LIGNUM Some Applications Conclusions

Process-based models Vegetative and reproductive growth Photosynthesis, respiration and carbon allocation Mineral metabolism, especially nitrogen metabolism Growth regulations Intra-tree transfer of metabolites

Morphological models L-systems Other mathematical presentations of branching systems

Here comes a pictrue from Algorithmic beauty of plants

Process-based model  Morphological model = Functional-structural model (FSM)

Features of a FSM A basic unit is used for presentation of both architecture and functioning (metabolism) These units are combined to form different organisational levels Local control

LIGNUM: General features Simple structural units account for both structure and functioning of trees. Annual net production is used to new growth. Pipe model and functional balance for partitioning of growth. Time step one growth period (one year).

LIGNUM: The structure

LIGNUM: Tree Segment for deciduous trees

LIGNUM: Releasing suppressed buds

LIGNUM: Carbon balance

LIGNUM: Length of new segments

LIGNUM: New buds

LIGNUM: The Radiation Submodel (self shading) Shading Shaded
