Table 1 Effects of mutagens on NOX activity in different coloured maize seeds. Effects of different concentrations of AO and EB on the NOX activity of white maize seeds. Means followed by the same letter are not significantly different (p < 0.05) among different treatments. For each treatment, five replicates were analysed. EB, ethidium bromide; AO, acridine orange; NOX, NADPH oxidase.
