∗ANOVA results are significant at 𝑃<0.01 except for Cu, which was significant at 𝑃<0.05 for species but not significant (NS) at 𝑃>0.05 for treatment and species (S) × treatment (T) interaction.
The same letter in the same column means no significant difference (𝑃>0.05) between treatments (all three species).
