Cadmium concentrations and translocation factors (TF) in tomato and cucumber grown hydroponically without or with added Si.

Treatment	Shoot	Root	Shoot	Root	Tomato	Cucumber
	Cd concentration (μg g^-1 DW)				TF (%)
	Tomato		Cucumber		Cd_shoot/Cd_root
Cd	1136 ± 125^a	6931 ± 893^a	659 ± 35.3^a	13346 ± 2069^a	16.8 ± 2.5^a	4.9 ± 0.4^b
Si + Cd	799 ± 54.8^b	6232 ± 353^a	550 ± 24.2^b	9486 ± 1219^b	13.0 ± 0.5^b	5.9 ± 0.3^a

Data are means ± SD. Values followed by different letters within a column represent significant difference at P < 0.05 according to t-test. Cd concentrations in control and Si treatments were undetected.
