Selenium Nanoparticles as Multifunctional Supplement to Provide Growth and Development of Agricultural Crops: Mechanisms, Effectiveness, Prospects and Limitations

The review discussed the effectiveness of using selenium nanoparticles (Se NP) in agricultural technologies. Based on the analysis of literature data, the proposed methods of applying Se NP were reviewed, the key mechanisms of action of Se NP on plants were summarized in the context of various activities of these nanoparticles (biostimulating, stress-protective, biofortification, nutraceutical, antioxidant) and the effectiveness of applying Se NP using "traditional" forms of mineral selenium fertilizers - selenate and selenite.
