Table I.

Total Hg content (μg Hg g dry weight plant⁻¹) in root and shoot plant tissues extracts analyzed separately from rape plants treated with different HgCl₂ concentrations

Total PC₂ content (μm PC₂ g fresh weight plant⁻¹) in roots. Values are means of three replicates. Means followed by different letters are significantly different by Duncan test with P < 0.05. Relationships of μm PC₂ g⁻¹ fresh weight with μm HgCl₂ g⁻¹ dry weight in rape showed linear correlation r² = 0.98, P < 0.05.
