Root Damage by Insects Reverses the Effects of Elevated Atmospheric CO2 on Eucalypt Seedlings
Figure 2
Plant biomass (dry) as affected by root damage and CO2.
Shoot and root mass of plants at aCO2 and eCO2 without (open bars) and with (closed bars) root damage (RD). Mean values ± S.E. shown, N = 24. Statistical significance of treatments indicated **(P<0.01) and *** (P<0.001) with lowercase superscript letters indicating significant differences (P<0.05) between treatments.
