Figure 3
The correlation matrix of nutritional and edapho-climatic traits evaluated in 21 Moroccan S. flexuosa (L.) Medik. ecotypes. Positive correlations are displayed in green and negative correlations in purple color. The color intensity and the size of the circle are proportional to the correlation coefficients. On the right side of the correlogram, the legend color shows the correlation coefficients and the corresponding colors.
