Unravelling the role of silica nanoparticles in alleviating chromium heavy metal stress in Mexican marigold (Tagetes erecta L.).

ABSTRACT: This study investigates the potential of silica nanoparticles (SiO₂ NPs) to alleviate chromium (Cr) stress in Tagetes erecta L. (Mexican marigold). For the purpose, their effects on plant growth, biochemical traits, and physiological responses were assessed. A completely randomized design (CRD) was employed using three replicates per treatment across nine treatment groups; T₁ = Control, T₂ = Cr-I (CrCl₃; 50 mg kg^-1), T₃ = Cr-II (CrCl₃; 100 mg kg^-1), T₄ = NPs-I (SiO₂ NPs; 100 mg L^-1), T₅ = NPs-II (SiO₂ NPs; 200 mg L^-1), T₆ = Cr-I + NPs-I, T₇ = Cr-I + NPs-II, T₈ = Cr-II + NPs-I, and T₉ = Cr-II + N
