Abstract: The effects of the co existing of cetyltrimethylammonium bromide(CTAB),a kind of cationic surfactant and Aluminium(Al 3+ ) on maize seedlings were studied.The results showed that CTAB could intensify the toxic effect of Aluminium on maize seedlings.The activities of protective enzymes,such as superoxide dismutase(SOD) and peroxidase(POD),increasing gradually,but activities of catalase(CAT) decreased,the generating rate of superoxide ions increased markedly,and so did membrane lipid peroxidation and plasma membrane permeability of the maize seedlings,however,the content of chlorophyll decreased.When the concentration of CTAB reached 1 0 cmc(critical micelle concentration),the photosynthesis rate and transpiration rate of the seedling dropped drastically.

Key words: Al3+, CTAB, maize seedling, toxicity
