| The incorporation of some genetic and physiological processes in a developmental model of Hordeum vulgare L. (barley) is presented. The model exhibits different hierarchical scales and has been conceived as a Relational Growth Grammar (RGG). RGG is a new formalism that has been developed as an extension of L-Systems and implemented using a new modelling language, eXtended Lsystems (XL). Models written in XL can be executed using the interactive, Java-based modelling platform GroIMP, which has been developed for this purpose. The barley model proper is a set of morphogenetic rules. These are combined with a set of rules representing a metabolic network simulating some key steps of the biosynthesis of gibberellic acid (GA1). The transport of GA1 and GA19 (a... |

| The concept of relational growth grammars (RGG) is a recent effort to address the needs of functional-structural plant modelling. The programming language XL is the first language that implements this concept; it is made available for plant modelling as part of the modelling platform GroIMP. In this paper, an introduction to relational growth grammars and XL will be given using simple but instructive examples. It will be shown how the proven formalism of L-systems is integrated seamlessly into RGG/XL, which new modelling possibilities are provided, and how some standard tasks of modelling can be implemented in XL. Moreover, the examples will demonstrate some of GroIMP’s 3D-geometric objects and algorithms that are useful for functional-structural plant... |
