The effect of nanoparticles on enzymatic antioxidant defense mechanisms in stressed plants. (a) Graph showing the effect of various nanoparticle treatments on superoxide dismutase (SOD) activity in salinity stressed plants. (b) Graph illustrating the changes in peroxidase (POD) activity in stressed and non-stressed plants. (c) Graph depicting ascorbate peroxidase (APX) activity in treated plants. (d) Graph depicting catalase (CAT) activity levels in treated plants. The data represent the mean values of three independent replicates, each containing three hills per pot, with error bars indicating the standard error of the mean. Bars annotated with different letters indicate statistically significant differences, as determined by Tukey’s multiple range test (treatment abbreviations are provided in the Materials and Methods section).
