Concentration of Ag in the roots, stems and leaves of the plants and Ag TF | ||||
Species | Ag roots | Ag stem | Ag leaves | Translocation factor |
(mg kg^{−1 }DW) | (mg kg^{−1 }DW) | (mg kg^{−1 }DW) | (× 100) | |
Brassica juncea | 82,292 a | 57,729 a | 6,156 a | 7.48 a |
(5,394) | (598) | (516) | (0.92) | |
Festuca rubra | 62,365 b | 2,777 c | 2,459 b | 3.94 b |
(1,990) | (2,738) | (258) | (0.36) | |
Medicago sativa | 19,715 c | 25,241 b | 4.31 c | 0.022 c |
(2,369) | (5,004) | (0.84) | (0.003) |
The means (n = 3) with the same letter were not significantly different (Bonferroni's test; p < 0.05). The mean standard error (n = 3) is in brackets. TF, translocation factor; DW, dry weight.
