Fig. 1 CO2 assimilation of the youngest leaf with a ligule in maize plants with root system damage caused by corn rootworm larval feeding or by mechanical cutting. Pots were infested 38 d after planting (V7 leaf stage). Late 3rd stage larvae and pupae were found 49 d after planting (V10 leaf stage). Mechanical damage to the 4th and/or 5th root nodes was performed 45 d after planting (V9 leaf stage) and again on the 6th node 51 d after planting (V11 leaf stage). Data points represent means for 4 replicate measurements per treatment. Upon obtaining a significant ANOVA for data within dates, LSD values represented by error bars were calculated
