Allocation of carbon – exponential function

The allocation of carbon as an exponential function, exemplified by the root allocation response function for above ground mass. The dark blue line is the original parameterisation. All the other parameterisations are compared with this one. The green line shows the effect on the allocation function of a doubling of the parameter, r_Mc1,. A doubling of r_Mc2 results in the turquoise line and finally a doubling of r_Mc3 gives the red line. This figure is analogous to the exponential leaf response function and the other exponential root response functions.
