Selenium nanoparticles enhanced growth, antioxidant enzyme activities and mineral absorbability of chrysanthemum plantlets
This study investigates the effects of selenium nanoparticles (SeNPs) on the growth, antioxidant activity, and mineral nutrient absorption of chrysanthemum plantlets in vitro. Chrysanthemum plantlets were cultured on media supplemented with varying concentrations of SeNPs (0.1, 0.3, 0.5, 0.7, 1.0, 1...
