“…Phenolic compounds, one from the most important secondary metabolites, naturally aggregate in plants, and as non-enzymatic antioxidants, act a vital role in plants tolerance to stressful conditions, [61]. In this regard, Azizi et al, [62] concluded that, application of magnetic treatment on tea plant promoted the production and accumulation of phenolic compounds in cell vacuoles, cell walls and trichomes of epidermal layers of plant, consequently protect other organelles (chloroplasts) under stress condition. Also, Upadyshev et al, [63] recorded that, the pulsed and rotating magnetic fields' complex effect resulted in enhancement of phenolic acid accumulation by about 71%, in Raspberry plants compared to the untreated control.…”
