The relationships between the first (a, c) and second (b, d) axes from the PCAs displayed in Fig 5 summarising variation in physiological traits on plant total dry mass at the final harvest: (a, b) without Al addition to the nutrient solution, (c, d) with Al supplied as 0.5 or 2.0 mM AlCl3. Fitted lines (a, b and c) are from multiple linear regression models using coefficients presented in S11a and S11b Table in S1 Appendix.
