Other claims from this paper (10)
- Mechanism In low P plants, a concurrent rise in root respiration consumed increased net carbon gain from phosphorus uptake.
- Observation Mycorrhizal and nonmycorrhizal roots had similar energy content.
- Mechanism The authors attribute increased root respiration in mycorrhizal roots mainly to fungal maintenance and growth respiration.
- Intervention effect Low phosphorus plants devoted a larger share of daily carbon budget to below ground respiration than moderate phosphorus plants on days 21, 28 and 35.
- Mechanism The relatively greater below ground respiration under low phosphorus was mainly attributed to increased root to shoot ratio.
- Observation Specific assimilation rate was significantly reduced at 21 and 28 days after planting.
- Intervention effect Low phosphorus reduced specific root respiration over time by up to 40%.
- Mechanism The reduction in specific root respiration reflected reduced ion uptake respiration and growth respiration.
- Intervention effect Maintenance respiration increased in low phosphorus plants.
- Mechanism The authors conclude root carbon costs primarily limit growth in low phosphorus soil.
