Effect of phosphate on arsenic uptake in Indian mustard seedlings
| Sample | Control | Potassium Phosphate |
|---|---|---|
| μmol g−1 fresh biomass | ||
| Root | 43.8 ± 1.6 | 12.3 ± 2.7 |
| Shoot | 1.1 ± 0.1 | 0.5 ± 0.1 |
Arsenic concentration determined by inductively coupled plasma spectrometry analysis in 2-week-old Indian mustard seedlings exposed to 500 μm arsenate for 3 d, in the presence or absence of 1 mm potassium phosphate in axenic hydroponic solution. Values are means ± se of three independent replicates.
