TABLE 4.

The Sb content of roots and leaves and the corresponding bioaccumulation factor (BF) and translocation factor (TF) values in tomato plants.

Treatments	Sb (μg Sb g^–1 FW)		BF		TF

	Roots	Leaves	Roots	Leaves
Control	4. 1 ± 1.1^c	nd	Nd	nd	nd
0.5 mM Sb	11332.0 ± 450.4^b	327.4 ± 28.2^b	182.3^a	5.46^a	0.030^b
1.0 mM Sb	13183.1 ± 375.3^a	554.9 ± 48.3^a	109.6^b	4.74^a	0.042^a

The data are from 10 independent experiments, each carried out in triplicate (different letters indicate significant differences at p < 0.05, Mann–Whitney U-test). BF, the ratio between the concentration of element in the roots or leaves and that present in the soil. TF, the ratio between the concentration of element in the leaves and in the roots.
