Diploid plants accumulated higher amount of Cd in both shoots and roots compared to tetraploid plants while Ni accumulation was ploidy-independent. Cd presence caused higher accumulation of total soluble phenols and flavonoids and higher phenylalanine ammonia-lyase and guaiacol-peroxidase activities in diploid cultivar in comparison with tetraploid but phenolic acids did not show direct correlation with metal accumulation and even decreased in the leaves of Ni-exposed plants. Lignin content was preferentially elevated in the roots of diploid cultivar. Among 17 free amino acids, their sum increased mainly in the leaves of Cd-exposed plants (owing to increase in serine, alanine and proline).
