Fig. 3. The relationship of reciprocal ratio of maximum leaf area fractions (F0) to k in the model of F = F0exp[–0.5(L – L0)2/k2] (Eq. [5]), the relative leaf area distribution model for all mature leaves on corn plants, where F = individual leaf area/plant leaf area, L0 is the downward leaf rank with the maximum area fraction of F0, k is a constant, and r is the correlation coefficient from model fitting.
