Fig. 4. Effects of elevated ozone and drought on the ratio of fine roots to leaves in total soluble sugar, starch and total non-structural carbohydrates of poplar saplings (mean ± SE). Different letters in the figures stand for the significant difference between treatments (p < 0.05). CF, charcoal-filtered air; NF40, non-filtered air + 40 nmol·mol-1 O3.
