A DYNAMIC MODEL OF NITROGEN METABOLISM IN HIGHER PLANTS. II. VALIDATION OF THE MODEL

Rafael Novoa1 y Dr. A. S. Loomis2

This paper ilustrates selected aspects of the validation of a nitrogen metabolism model in higher plants. Out puts of the model are compared with experimental data, and examples of sensitivity and behavior analysis are shown. The model provides good simulations for nitrate uptake, and light-dark daily transitions, and shows a realistic behavior in many aspects. Limitations of the present model and possible areas of improvement are discussed.
