Mean values (±standard error) of biomasses fractions at final harvest determined for the four replicate selection linages of Brassica napus grown in a phytotron environment at the four possible combinations of two temperatures and [CO₂] regimes (Table 1) in two generations: (a) aboveground DW, (b) Leaves DW, (c) Stems DW, (d) Seeds DW, (e) Seed Quantity, (f) thousand seed weight (TSW) F0 – ancestral stock population, F4 – fourth descendant population selected in the corresponding environments – gray-filled, round symbols connected by a line. Treatments: green – Ctrl (control), blue – elevated [CO₂] (C), red – increased temperatures (T), orange – elevated [CO₂] and increased temperatures (CT). Point characters of the same shape represent RSLs with the same identity. Boxplots show the difference in slopes between the trans-generational response in the given treatments and the control scenario for the four RSL: (trait value mean_F4 – trait value mean _F0)^{C, CT, T} – (trait value mean_F4 – trait value mean _F0)^Ctrl, DW, dry weight; TSW, thousand seed weight.
