Figure 3. Leaf traits as affected by CO₂ and root damage.

Effects of aCO₂ and eCO₂ on (A) specific leaf mass and (B) leaf water content (%) with (closed bars) and without (open bars) root damage (RD). Mean values ± S.E. shown, N = 24. Statistical significance of treatments indicated *(P<0.05) with lowercase superscript letters indicating significant differences (P<0.05) between treatments.
