Other claims from this paper (9)
- Intervention effect Elevated CO2 increased total net carbon uptake in ectomycorrhizal Scots pine seedlings.
- Intervention effect Extra carbon under elevated CO2 did not increase shoot mass.
- Intervention effect In Suillus-inoculated seedlings, extra carbon moved to roots and decreased the shoot-to-root ratio.
- Intervention effect Laccaria-inoculated seedlings did not incorporate additional carbon in root or fungal tissue.
- Intervention effect Laccaria-inoculated seedlings increased below-ground respiration.
- Observation S. bovinus acquired or transferred nitrogen better than L. bicolor.
- Association Under elevated CO2, S. bovinus enabled greater net carbon uptake than L. bicolor.
- Association Shoot nitrogen concentrations in Suillus-inoculated seedlings were twice those in Laccaria-inoculated seedlings irrespective of CO2.
- Mechanism The authors infer that positive response to elevated atmospheric CO2 is strongly fungal-species specific.
