Isotope discrimination against 13C (Δ13C), calculated from isotope composition data (δ13C). Data are shown according to treatments (control, C; winter resprouts, RW; summer resprouts, RS), material analysed (dry matter, DM; water-soluble extract, WSE) and season (winter and summer). Values are mean ±SE of 6 replicates. Significant differences across rows or columns (p ≤ 0.05) are indicated by different letters: treatment (a, b, c), season (A, B) and material analysed (α,β).
