Equation (14) is rewritten as:
(17)with the initial condition:
(18)where 
. In Figure 2 (left), Equation (17) is plotted for different values of m and for 
. In case 
the crop reacts to water stress by strongly reducing its transpirative capacity, on the contrary, if 
the crop reacts by only weakly reducing it. The limit case 
means that the crop does not react to the water shortage and always tries to satisfy the maximum transpirative demand.
