Abstract
The nutrient-absorbing power of the root [α] is related to its radius, and the diffusion coefficient of its cortex, on the basis of a steady-state model of long-term transport from the root surface to the shoot. Values of a ‘critical’ radius are calculated above which α should increase only slightly with increasing root radius.Keywords
