Other claims from this paper (10)
- Intervention effect Low nitrogen decreased crown root number by 40%.
- Intervention effect Low nitrogen increased crown root elongation rate rather than growth duration.
- Intervention effect Low nitrogen did not lengthen crown root growth duration.
- Intervention effect Only younger crown roots were significantly responsive to low nitrogen.
- Intervention effect Low nitrogen increased the lateral-root-to-crown-root ratio.
- Intervention effect Low nitrogen added approximately 70 m to lateral root length.
- Intervention effect Low nitrogen increased second-order lateral root density.
- Intervention effect Low nitrogen increased variation in lengths of opposing lateral root pairs.
- Intervention effect Low nitrogen decreased root hair length and density.
- Mechanism Root hair responses may be indirect effects of lower biomass or demand under low nitrogen.
