Relative phosphorus uptake by rice (mg P g−1 relative dry weight) after transfer to treatment for 8 d: aerated at 1·6 μm P (A LP), and 200 μm P (A HP) and stagnant at 1·6 μm P (S LP) and 200 μm P (S HP) nutrient solution culture. Phosphorus uptake per unit rice root weight was measured after subtracting the initial (day 0) P content of the 28-d-old plants. Bars represent standard errors of three replicates.
