Species with higher baseline MAA levels (measured in control samples at day 5) tended to experience smaller Y(II) decreases under UV-B exposure, as suggested by a negative trend with ΔY(II) ( ρ = −0.78; p ≈ 0.06–0.08).
Species with higher baseline MAA levels (measured in control samples at day 5) tended to experience smaller Y(II) decreases under UV-B exposure, as suggested by a negative trend with ΔY(II) ( ρ = −0.78; p ≈ 0.06–0.08).
In contrast, MAA fold change showed a positive trend with ΔY(II) ( ρ = +0.77; p ≈ 0.07–0.08), where species with low constitutive MAA levels but strong inducible increases also displayed larger declines in Y(II).
