The model includes a shoot number submodel, a carbon assimilation and allocation submodel, and a nitrogen uptake and allocation submodel.
Growth is partitioned into blade, sheath, stem and flower components.
Simulated processes include shoot growth, tillering, root growth, photosynthesis, nitrogen uptake, and translocation. Results for East Africa graminoids suggest that an increased understanding of primary production and plant adaption could result from increased attention to the interactions among morphological traits and physiological processes. Modelling primary production of perennial graminoids- uniting physiological processes and morphometric traits.
