Toxic effects of Cd2+ pollution on the biochemical and physiological characters and ultrastructure of Alternanthera philoxeroides

Abstract

Abstract: By imitating different concentration Cd²⁺ polluted water environment, this paper dealt with the changes of some biochemical and physiological characters and the damage of ultrastructure in leaves of Altemanthera philoxe-roides.The result showed that SOD and POD activity first increased in the low concentration pollution and then decreased with the concentration of pollution raised.The content of chlorophyll, chlorophyll a/b value, CATactivity and the content of soluble protein all declined continually.With the concentration of pollution increased, the ultrastructure of cell nuclei, chloroplast and mitochondria became deformed, the permutation of structure inside disordered, swelled, membrane disrupted and vesiculated.The changes of some biochemical and physiological characters accorded with the damage of cell ultrastructure.

Key words: Cd²⁺, Pollution of heavy metal, Alternanthera philoxeroides, Antioxidant enzyme systems, Ultrastructure
