Other claims from this paper (10)
- Intervention effect Root architecture of upland rice was significantly affected by the P and water treatments.
- Intervention effect The moist, high P scenario had 2.8 times the root mass of the dry, low P scenario.
- Intervention effect The moist, high P scenario had double the number of nodal roots of the dry, low P scenario.
- Intervention effect The moist, high P scenario had more S-type laterals than the dry, low P scenario.
- Intervention effect Plant P uptake of upland rice increased more than 3-fold with increasing P and water supply.
- Intervention effect Drying periods did not reduce P uptake at low P supply.
- Method / resource The simulation adequately predicted P uptake in all scenarios when the Michaelis-Menten constant was corrected for diffusion limitation.
- Mechanism Laterals (S- and L-type) and growing root tips are the key drivers of P uptake in the simulation.
- Association L-type laterals became more important than S-type laterals for overall water and P uptake in dry scenarios.
- Method / resource The functional-structural model can predict the P and water uptake of specific rice roots when the root system structure is known.
