Effect of silicon dioxide nanoparticles (SiO2 NPs) on the content of photosynthetic pigments of wheat seedlings infected by R. solani. (A) Chlorophyll a (mg g−1 FW), (B) Chlorophyll b (mg g−1 FW), and (C) Carotenoids (mg g−1 FW). Data presented are means ± standard deviation (mean ± SD) of five biological replicates. Different letters indicate statistically significant differences among treatments, while the same letters signify no significant differences between them according to Tukey’s honestly significant difference test (p < 0.05).
