Significance testing of the relationships between carbohydrate concentrations and species holoploid genome size (GS, 1C value). Generalized least squares models were used (d.f. = 4/107 in all cases). For each model term, F- and P-values are indicated. For each model, Cox and Snell pseudo-coefficient of determination (R2) and estimated compound symmetry correlation (Rho) for within-species measurements are indicated. (a) Total non-structural carbohydrates (TNC), (b) mono- and disaccharides (glucose, fructose and saccharose), (c) starch and (d) water-soluble reserves, i.e. mainly fructans + raffinose family oligosaccharides (RFOs) and sugar alcohols.
