Figure 4From: Leucaena leucocephala leachate compromised membrane integrity, respiration and antioxidative defence of water hyacinth leaf tissuesIn situ tissue localisation of superoxide generation in water hyacinth leaf discs treated with 48Â h leachate at different concentrations. Formation of dark blue spots all over the leaf discs treated with 2.5 and 5% leachates indicate greater levels of superoxide production compared with control leaf discs treated with deionised water (0% leachate).Back to article page
