Conteúdo: | Contamination with trace elements is characterized by an abiotic stress that represents a limiting factor in agricultural production. Considering that cadmium (Cd) and Zinc (Zn) are physically and chemically similar, they can interact with the environment, causing antagonistic or synergistic effects. In this sense, physiological mechanisms to exclude, detoxify or compartmentalize the excess of those trace elements is crucial for the survival of the plants under conditions of high concentrations of these elements. In order to understand the responses of the species sensible to the presence of Cd and Zn, this study aimed to access the behavior of maize plants (Zea mays L.) cultivated in Cambisoils and Latosol with growing concentrations of Cd/Zn in a 21 days period. Growth and biochemical analyzes were performed such as antioxidant enzyme SOD, CAT and APX activity, hydrogen peroxide and lipid peroxidation. The data obtained evidenced the specific behavior of maize plants grown in Cambisoils compared to Latosol, showing a superior activity of all the enzymes analyzed, and also a lower content of hydrogen peroxide and lipid peroxidation. The interaction between both the elements resulted in a synergistic effect, negatively influencing all the analyzed parameters.
