Title

Responses of dry weight growth under SO ₂ stress in an SO ₂ ‐tolerant plant, Polygonum cuspidatum

Toshiki Natori; Tsumugu Totsuka Ecological Research 1988. doi:10.1007/bf02348690

Other claims from this paper (7)

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.
Mechanism 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.
