NITRATE AND NITROGEN SIMULATION PAGE

April 25, 1996

Introduction

This page contains information about a mathematical model for simulation of nitrate and nitrogen use by plants. The model and the related grafting experiments are presented in a paper in the Journal of Experimental Botany (June 1997).

Fig.1 - The scheme of the model

U - nitrate uptake
NR - nitrate reduction by nitrate reductase
P - carbon uptake (photosynthesis)

Simulations

We offer you several ways of running our model.

Experimental approaches

A visual guide to grafting pea seedlings.
This method is described also in the above mentioned paper.
