Pages, L. | Jordan, M.O.
The present model describes the root system as a set of root axes, characterised by their orders and their inter-node of origin. The growth and development are simulated by three elementary processes, occurring at each time step: (i) emission of new primary root axes from the shoot, (ii) growth and (iii) branching of existing root axes. The elongation of an axis depends on its order, inter-node and local growing conditions. Branches appear acropetally at a specified distance from the apex and from former branches, along ranks facing xylem poles, with a branching angle specific to their order and inter-node. From the branched patterns various outputs, such as root profiles or cross-section maps can be computed, compared to observed data and used as inputs in uptake models.
