Leaf-specific theoretical conductance remains constant with height growth in Moringa oleifera. (A) Theoretical whole-plant conductance (K_plant) scales statistically identically with height, as does leaf area, as K_plant ∝ H^1.825 (see Fig. 1A). (B) K_plant scales isometrically with total leaf area, congruent with expectations regarding the way in which selection should favor individuals with constant photosynthetic productivity per unit leaf area with height growth. Confidence intervals for slopes and intercepts are shown in Table 1. P<0.001 for all R². n=139 in all cases.
