A. Vanderwerf et al., ALLOCATION OF CARBON AND NITROGEN AS A FUNCTION OF THE INTERNAL NITROGEN STATUS OF A PLANT - MODELING ALLOCATION UNDER NON-STEADY-STATE SITUATIONS, Plant and soil, 156, 1993, pp. 183-186
In this paper we model allocation of carbon and nitrogen to roots and
leaves as a function of the nitrogen status of a plant. Under steady-s
tate conditions, allocation of carbon and nitrogen to leaves is expone
ntially (positively) correlated with plant nitrogen concentration, whe
reas allocation to roots is correlated negatively, also in an exponent
ial manner. Allocation functions derived under steady-state conditions
are used to simulate biomass partitioning under non-steady-state nutr
ient conditions. Upon nitrogen deprivation, measured and simulated val
ues are rather similar with time, suggesting that allocation functions
derived under steady-state conditions also hold under non-steady-stat
e conditions.
