Figure 2 in Effects of nitrogen and phosphorus availability on the early growth of two congeneric pairs of savanna and forest species

Figure 2. The effect of our four treatments (Com: Complete Hoagland solution; -N: Solution without nitrogen; -P: Solution without phosphorus and -NP: Solution without both macronutrients) in the grow of a congeneric pair of species after 45 days of experiment. The boxes in the left side represent the savanna species (Enterolobium gummiferum), those on the right side, the forest ones (E. contortisiliquum).
