摘    要:By imitating different concentration Cd^2 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, CAT ac-tivity 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 in-side disordered, swelled, membrane disrupted and vesiculated. The changes of some biochemical and physiological characters accorded with the damage of cell ultrastrueture.

关 键 词:Cd^2+  Pollution  of  heavy  metal  Altemanthera  philoxemides  Antioxidant  enzyme  systems  Ultra-structure

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, CAT activity 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.
Keywords:Cd~(2+)  Pollution of heavy metal  Alternanthera philoxeroides  Antioxidant enzyme systems  Ultrastructure
