We show a possibility to extend analysis tools for measured and simulated plants using a data interface between the simulation model LIGNUM and the multifunctional software system GROGRA. Both systems were developed by different teams. To demonstrate the enhanced possibilities for analyzing a LIGNUM tree, several examples are given. In these examples three different approaches for analysis are applied to measured and simulated trees: Fractal dimension, deduction of tapering laws, and water potential patterns obtained from simulation of waterflow by the specialized software HYDRA. Conclusions for the interfacing and comparison of different modelling tools are drawn.}, language = {en} } @article{KurthOppeltDzierzonetal., author = {Kurth, Winfried and Oppelt, Armin L. and Dzierzon, Helge and Jentschke, Georg and Godbold, Douglas L.}, title = {Structure and fractal dimensions of root systems of four co-occurring fruit tree species from Botswana}, language = {en} } @article{Kurth, author = {Kurth, Winfried}, title = {Towards universality of growth grammars : Models of Bell, Pages, and Takanaka revisited}, language = {en} } @article{KurthSloboda, author = {Kurth, Winfried and Sloboda, Branislav}, title = {Tree and stand architecture and growth described by formal grammars.
