Table 1.
Selenium (Se) speciation in shoots of oilseed rape treated with soil Se, Se+Cd, or Se+Pb after a planting time of 60 days (Dry biomass weight, DBW).
| Treatments (mg kg-1) | Total Se (mg kg-1) | SeMet (mg kg-1) | Se4+ (mg kg-1) | SeMet as percentage of total Se | Se4+ as percentage of total Se |
|---|---|---|---|---|---|
| 15Se | 29.95 ± 0.12a | 2.584 ± 0.05a | 0 | 8.63% | 0 |
| 15Se+300Pb | 28.63 ± 0.18a | 5.473 ± 0.04b | 2.783 ± 0.06 | 19.12% | 9.72% |
| 15Se+500Pb | 25.92 ± 0.14a | 4.298 ± 0.08b | 1.225 ± 0.03 | 16.60% | 4.72% |
| 15Se+1Cd | 26.58 ± 0.25a | 6.841 ± 0.05b | 0 | 25.74% | 0 |
| 15Se+5Cd | 19.89 ± 0.15b | 5.447 ± 0.06b | 0 | 27.36% | 0 |
All data show the means+SE of three replicates. Different letters mean significance of difference between the treatments (p ≤ 0.05).
