Electromagnetic field (EMF) causes fundamental alternations in biological systems. In this study, we studied the effects of EMF on physiological responses and secondary metabolites production in SiO₂ NP-treated Anthemis gilanica plants. The results indicated that EMF improved plant growth by inducing chlorophyll and carotenoid content, which led to enhanced biomass in SiO₂ NP-treated plants. EMF enhanced adventitious roots in SiO₂ NP-treated plants. EMF treatment improved the activity of antioxidative enzymes such as superoxide dismutase, catalase, and peroxidase in both control and SiO₂ NP-treated plants. EMF and SiO₂ NP treatments significantly declined hydrogen peroxide content in A. gilanica plants. Although protein content was reduced by SiO₂ NP treatment, combined application of EMF with SiO₂ NP caused a significant induction in protein content. Our results presented that EMF induced secondary metabolites accumulation such as flavonoid and phenol in SiO₂ NP-treated A. gilanica plants. This work can open prospects for the production of the pharmaceutically high-value secondary metabolites.
