Descripción
Crop models such as CERES and CropSyst treat canopies as homogeneous entities without attempting to define canopy geometry, other than row structure, or deal with growth processes at time steps shorter than one day. A functional-structural modelling approach can improve canopy simulation, in particular of indeterminate crops such as faba bean. A major challenge is to incorporate the plasticity of the canopy. Functional-structural models can attend to this by introducing variation in several ways and at different levels of canopy composition. ALAMEDA is a functional-structural model of a faba bean (Vicia faba L.) crop that addresses these issues. An L-system provides the basic conceptual and program structures within which functional relationships can be connected, thus playing a comparable role that physical plant structure provides for physiological processes, i.e. specifying where an equation has to be applied or directing the information flow. According to previous studies with faba bean, the stem was selected as the main building module. An associated growth model is linked to calculate the lengths of the vegetative organs and leaf allometries are used to compute leaf area. ALAMEDA is currently being extended by including a model of radiation interception and functions from classic models, for example, the variation of specific leaf area with temperature as specified in CROPGRO-legume.
