Table 2 Effects of lead heavy metal on plant biomass and relative water content (RWC) of E. crassipes seedlings

From: Lead heavy metal toxicity induced changes on growth and antioxidative enzymes level in water hyacinths [Eichhornia crassipes (Mart.)]

Pb Conc. (mg/L)	Biomass (g/seedlings)		Relative water content (RWC)%
Pb Conc. (mg/L)	Fresh weight (FW)	Dry weight (DW)	Relative water content (RWC)%
0.0	10.03 ± 0.033^a*	0.727 ± 0.004^a*	92.73 ± 0.06^e*
100	09.95 ± 0.043^a	0.712 ± 0.007a	92.84 ± 0.07^d
200	09.63 ± 0.031^b	0.640 ± 0.003^b	93.35 ± 0.05^b
400	08.84 ± 0.141^c	0.564 ± 0.012^b	93.61 ± 0.04^a
600	07.95 ± 0.142^d	0.532 ± 0.005^c	93.30 ± 0.03^b
800	07.26 ± 0.167^d	0.500 ± 0.006^c	93.11 ± 0.03^c
1000	06.90 ± 0.063^e	0.485 ± 0.001^d	92.97 ± 0.04^d

*Values are expressed as mean ± SE (n = 3), different letters in each column indicate significant difference at p < 0.05 levels.
