Pearson correlation matrix determined from the 24 accessions and the ecotype Col-0 for enzymatic saccharification efficiency (SE%), biomass production (FW; DW/FW), PAM1 epitope level (PAM1), degree of methylesterification (DM%), uronic acid content/mg of AIS (UA/AIS), ratio between pectin fraction (μg sugars), mg of cell wall (ChASS/AIS), and biomass parameter (FW and DW). The only significant correlation is indicated in bold. AIS, alcohol-insoluble solids; ChASS, chelating agent-soluble solids; Col-0, Columbia-0; DM, degree of methylesterification; DW, dry weight; FW, fresh weight; SE, saccharification efficiency; UA, uronic acid.
