Resumo: ABSTRACT Purple maize is a source of natural pigments that can be used for various industrial purposes; however, soil contamination from aluminium affects production. The aim of this study was to evaluate the effect of aluminium toxicity associated with different temperatures on seed germination and initial development in purple maize seedlings, through germination, initial seedling growth and indicators of oxidative damage. The experimental design was completely randomised in a 5×2 factorial scheme (concentrations × temperatures). The parameters under evaluation were germination percentage, length and total dry weight of the root system and shoots, and indicators of oxidative damage (chlorophyll a, chlorophyll b and total chlorophyll, total carotenoids and lipid peroxidation) at the seedling stage. Aluminium chloride concentrations have no effect on seed germination in purple maize. With increasing aluminium concentrations, the length, dry weight, chlorophyll a, chlorophyll b, total chlorophyll and total carotenoids of normal purple maize seedlings are reduced, while lipid peroxidation increases. Aluminium toxicity stress in purple maize seedlings can be detected using biochemical indicators (chlorophyll a, chlorophyll b and total chlorophyll, total carotenoids and lipid peroxidation).
