Other claims from this paper (17)
- Intervention effect AM fungal inoculation significantly increased shoot dry matter yield at P0 and P10.
- Intervention effect AM fungal inoculation significantly increased shoot P uptake at P0 and P10.
- Intervention effect AM fungal inoculation increased root length.
- Intervention effect AM fungal inoculation increased P concentration in soil solution.
- Intervention effect AM fungal inoculation decreased or maintained the root:shoot ratio.
- Observation About half the roots of inoculated plants were infected by AM fungi.
- Observation External hyphae amounted to 20 m g-1 soil at P10 and P200.
- Observation Hyphal surface area of infected roots was 11 cm-2 cm-2 root at P0.
- Observation Hyphal surface area of infected roots was 2 cm-2 cm-2 root at P10.
- Observation The infected root had up to fivefold higher P influx.
- Method / resource Model-calculated hyphal P influx exceeded measured influx.
- Method / resource The modeled P uptake capacity of hyphae was too high.
- Method / resource The model found a narrow depletion zone around roots or hyphae.
- Method / resource The model estimated roots alone access phosphorus from 7% of soil volume.
- Method / resource The model estimated hyphae access phosphorus from 100% of soil volume.
- Mechanism The authors partly attributed greater P uptake after AM inoculation to higher soil-solution P.
- Mechanism The authors partly attributed greater P uptake after AM inoculation to increased absorbing area from external hyphae.
