Table 3 Effects of different lead (Pb) levels of nutrient solution on root and shoot concentrations of Pb (mg kg⁻¹ DW) in young and mature plants of garden cress

From: Plant growth stage influences heavy metal accumulation in leafy vegetables of garden cress and sweet basil

(mg L⁻¹)	Shoot Pb		Root Pb
(mg L⁻¹)	Young plants	Mature plants	Young plants	Mature plants
Pb 0	0.04 ± 0.02c	0.35 ± 0.13c	0c	0c
Pb 5	16.3 ± 3.06b	10.8 ± 1.9b	239 ± 24b	196 ± 18b
Pb 10	27.8 ± 3.12a	17.9 ± 2.6a	315 ± 30a	311 ± 29a

In each plant and for a given trait, means with at least one common letter are not significantly different at 5% level of Duncan's multiple range test
