چکیده
Abstract Selenium (Se) is indispensable for animals and humans. One option to address Se deficiency biofortify plants with Se. Biofortification of forage nanoparticles (NPs) gaining more attention as an efficient safe source livestock. The purpose this study was investigate the effect different concentrations NPs-Se (0, 30, 50, 100, 150, 250 mg·L −1 ) on growth alfalfa harvested multiple times, provide a basis production Se-enriched forages. Applying 50 concentration had best yield over three harvests. Over harvests, low-dose (30 application significantly increased peroxidase superoxide dismutase activities, chlorophyll content carotenoid content, decreased malondialdehyde content. total accumulation in at same harvest showed upward trend increasing concentration. At concentration, from first third harvest, initially then decreasing trend. evaluation found that foliar could have greatest positive multiple-harvested alfalfa.

Selenium (Se) is an essential trace element for humans and other mammals. Most dietary Se is derived from crops. To develop a Se biofortification strategy for wheat, the effect of selenate fertilization and bacterial inoculation on Se uptake and plant growth was investigated. YAM2, a bacterium with 99% similarity to Bacillus pichinotyi, showed many plant growth promoting characteristics. Inocul...

Se is an essential element for animals. In man low dietary Se intakes are associated with health disorders including oxidative stress-related conditions, reduced fertility and immune functions and an increased risk of cancers.

Selenium (Se) is an essential trace element for humans and animals but at high concentrations, Se becomes toxic to organisms due to Se replacing sulfur in proteins. Selenium biofortification is an agricultural process that increases the accumulation of Se in crops, through plant breeding, genetic engineering, or use of Se fertilizers. Selenium phytoremediation is a green biotechnology to clean ...
