“…All other parameters were measured using a handheld ruler. An empirical model of M. truncatula development capturing differences in plant structure due to the different nutrient treatments was developed using the L-system-based L-studio software from the University of Calgary (Prusinkiewicz et al, 2000). L-systems are a formalism for describing plant development (Lindenmayer, 1968) that can support a wide range of empirical and mechanistic modeling approaches (Prusinkiewicz, 2004;Mundermann et al, 2005).…”

Medicago truncatula has become a model system to study legume biology. It is imperative that detailed growth characteristics of the most commonly used cultivar, line A17 cv Jemalong, be documented. Such analysis creates a basis to analyze phenotypic alterations due to genetic lesions or environmental stress and is essential to characterize gene function and its relationship to morphological development. We have documented morphological development of M. truncatula to characterize its temporal developmental growth pattern; developed a numerical nomenclature coding system that identifies stages in morphological development; tested the coding system to identify phenotypic differences under phosphorus (P) and nitrogen (N) deprivation; and created visual models using the L-system formalism. The numerical nomenclature coding system, based on a series of defined growth units, represents incremental steps in morphological development. Included is a decimal component dividing growth units into nine substages. A measurement component helps distinguish alterations that may be missed by the coding system. Growth under N and P deprivation produced morphological alterations that were distinguishable using the coding system and its measurement component. N and P deprivation resulted in delayed leaf development and expansion, delayed axillary shoot emergence and elongation, decreased leaf and shoot size, and altered root growth. Timing and frequency of flower emergence in P-deprived plants was affected. This numerical coding system may be used as a standardized method to analyze phenotypic variation in M. truncatula due to nutrient stress, genetic lesions, or other factors and should allow valid growth comparisons across geographically distant laboratories.

“…GROGRA was specifically tailored to the simulation of forest trees in ecophysiological applications. (There exist other L-system softwares, e.g., L-Studio/cpfg; Prusinkiewicz et al 2000). Beyond the pure grammar interpretation, GROGRA provides additional features which form our main focus of interest here: A data filter to represent measured trees, interfaces linking it to process-oriented simulation tools and to statistical software ( Fig.…”

In recent years, many different advanced mathematical models and simulation systems for tree and forest growth have been developed. 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.

“…Subsequently, they designed a plant-modeling language called cpfg [18], which supports both context-free and context-sensitive generating rules. They also implemented the plant modeling software L-Studio based on cpfg [20]. Recently, Prusinkiewicz et al [21] also proposed the use of positional information to control parameters along a plant axis.…”

The Sketch L-System: Global Control of Tree Modeling Using Free-Form Strokes

Abstract. L-system is a tool commonly used for modeling and simulating the growth of plants. In this paper, we propose a new tree modeling system based on L-system that allows the user to control the overall appearance and the depth of recursion, which represents the level of growth, easily and directly, by drawing a single stroke. We introduce a new module into L-system whose growth direction is determined by a user-drawn stroke. As the user draws the stroke, the system gradually advances the growth simulation and creates a tree model along the stroke. Our technique is the first attempt to control the growth of a simulation in L-system using stroke input.
