Distribution of accessions of P. pratense, P. nodosum and P. alpinum based on differences between WL and NWL in the shoot and root traits and the root anatomy traits. (A) PCA where data points represent an accession. For measured traits (SDW, ΔTN, ΔLN and RA), proportional differences between WL and NWL were used, and for the remaining calculated traits (RGR-TN, RGR-LN, %RDW, 5RDW:RDW, AA:CAE, CAE:SA), the absolute differences were used. (B) HCA based on the same traits as for the PCA. Abbreviations can be found in Table 2.
