Other claims from this paper (14)
- Intervention effect Increasing nitrate from 0.01 to 1.0 mmol/L significantly increased lateral root length and root biomass.
- Intervention effect In 478, lateral root density changed little with nitrate increase up to 10x10(-3) mol/L.
- Intervention effect Lateral root density decreased significantly with increasing nitrate beyond the threshold levels.
- Intervention effect The inhibitory effect of high nitrate on root growth was weaker in 478 than in Wu312.
- Intervention effect Lateral root growth in Wu312 was completely inhibited by nitrate at 10x10(-3) mol/L.
- Intervention effect Lateral root density of 478 could reach 30% of its maximum (axial) even at 20x10(-3) mol/L nitrate.
- Intervention effect Lateral root density of 478 could reach 50% of its maximum (radicle) even at 20x10(-3) mol/L nitrate.
- Association Shoot total N and shoot nitrate content increased with increasing nitrate level.
- Association Shoot/root ratio followed an exponential decay function.
- Association LR density followed a Gaussian function of shoot nitrogen and nitrate.
- Association LR length followed a parabolic function of shoot nitrogen and nitrate.
- Association Shoot/root ratio increased rapidly when shoot N content exceeded about 1.6 mol/kg and nitrate content exceeded 0.22 mol/kg.
- Association LR density began to decrease when shoot N content exceeded about 1.5 and nitrate content exceeded 0.16 mol/kg.
- Association LR length began to decrease when shoot N content reached about 1 mol/kg and nitrate content reached 0.10 mol/kg.
