Medicago sativa L. Plant Response against Possible Eustressors (Fe, Ag, Cu)-TiO₂: Evaluation of Physiological Parameters, Total Phenol Content, and Flavonoid Quantification.

ABSTRACT: The present study analyzed Medicago sativa L. crops irrigated by TiO₂ in the anatase phase and TiO₂ doped with Ag, Fe, and Cu ions at 0.1%w synthesized using the sol-gel method (SG) and the sol-gel method coupled with microwave (Mw-SG). The materials were added to the irrigation water at different concentrations (50, 100, and 500 ppm). Stress induction by nanomaterials was observed by measuring stem morphology, chlorophyll index, total phenols and flavonoids, and antioxidant activity through the DPPH (2,2-diphenyl-1-picrylhydrazy) radical inhibition assay. The nanomaterial treatments caused statistically significant reductions in parameters such as stem length, leaf size, and chlorophyll index and increases in total phenol content and DPPH inhibition percentage
