Fig. 1. Effects of elevated ozone and drought on the total non-structural carbohydrates (TNC) content in leaves (A) and fine roots (B) of poplar saplings (mean ± SE). The same lowercase letter in the figures stands for non-significant difference between treatments (p > 0.05). CF, charcoal-filtered air; NF40, non-filtered air + 40 nmol·mol-1 O3.
