Fig. 8. Mineral composition of shoots of plants grown at two levels of nutrient supply in the presence of Al (AN + Al and LN + Al treatments). Nutrient concentrations are shown in grams per kilogram (g kg^-1) of dry weight. Numbers designate the maximum values of the scales of five different axes, each used to plot the concentration of a single nutrient. Asterisks indicate statistically significant differences between the two treatments (P < 0.05).
