Abstract

The expanded growth model provides a mathematical relationship for accumulation of biomass with time for plant tops (above-ground portion). In this article a hyperbolic relationship is shown to provide reasonable coupling between root and top accumulation with time for corn (Zea mays L.). These results suggest that the rate limiting step is biomass accumulation in the tops by photosynthesis, and that root-to-top coupling can be treated as quasi-equilibrium.
