Claim · model-written summary
The authors infer that changes in leaf and root growth under SO 2 may compensate for reduced carbon assimilation and maintain the carbon-to-nitrogen absorption ratio.

Verbatim
e0“an increase in leaf area and/or leaf dry weight and a decrease in root dry weight in P. cuspidatum under SO 2 stress may be induced in order to compensate for the decrease in CAR and to maintain the ratio of total leaf carbon absorption to total root nitrogen absorption in the early stage of vegetative growth”

- Intervention effect SO 2 exposure did not significantly decrease total dry weight relative to controls.
- Intervention effect SO 2 exposure increased leaf area and/or leaf dry weight relative to controls.
- Intervention effect SO 2 exposure decreased root dry weight relative to controls.
- Intervention effect SO 2 exposure slightly decreased leaf carbon assimilation rate.
- Intervention effect SO 2 exposure clearly decreased net photosynthesis.
- Intervention effect SO 2 exposure decreased the stem-plus-root dry weight to leaf area ratio relative to controls.
- Intervention effect The total leaf carbon absorption to total root nitrogen absorption ratio was similar in SO 2 exposed plants and controls.
