Biplots of PCA main factors (left) and scatterplots of case scores (corresponding to the pots of the experimental treatments (right) extracted for the plant variables measured in the aboveground parts of A. capillaris (above) and of M. albus (below). We have mentioned in the biplot a multiple regression equation (with standardized coefficients) that predicts the LP and biomass. The legends of the treatments are as shown in Fig. 2, and the legends of the variables are as described in the Methods section.
