Both selenium (Se) and anthocyanins are crucial for maintaining human health. Preharvest Se treatments could promote anthocyanin biosynthesis augment levels in vegetables, helping to combat deficiencies dietary intake. However, it remains unknown whether preharvest treatment balance growth plants what the appropriate concentration is. In this study, with sodium selenite at varying concentrations (0, 5, 10, 30 mg/kg) affect nutritional quality of purple leaf mustard ( Brassica juncea ) abundant anthocyanins. Lower (≤10 enhanced photosynthesis, facilitated root system development, consequently elevated biomass. Conversely, higher (≥30 reduced photosynthesis The dosage-dependent effects were corroborated through seedlings cultivated hydroponic conditions. Moreover, nearly all contents various nutrients mustard, particularly organic se. These results suggest an overall enhancement plants. Furthermore, application 10 mg/kg significantly activity phenylalanine ammonia-lyase upregulated expression 12 genes pivotal biosynthesis, further demonstrating fortified enrichment on mustard. Low-level resulted heightened antioxidant (APX, CAT, POD), mitigating reactive oxygen species induced by increasing content tissues. activities may be beneficial normal under stress conclusion, our study demonstrated This offers valuable insights into fortification methods agricultural practices, ensuring that such does not compromise leafy vegetable yield.
