Effect of Selenium Nanoparticles on Germination of Hordéum Vulgáre Barley Seeds

Abstract

Within the framework of this study, the effect of nanoparticles of the essential trace element selenium stabilized by Polyvinylpirrolidone (PVP) C15 (8 ± 2 kDa) and ascorbic acid on the germination of barley seeds has been studied. Selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid, characterized by a spherical shape, monodisperse size distribution, and a diameter of about 70 ± 5 nm, were obtained by the chemical reduction method. The experiment compared the effect of selenium nanoparticles and selenous acid on seed germination. The positive effect of preparation of selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid on the length of roots and shoots, the number of roots, and the percentage of seed germination has been revealed. It was determined that the highest percentage of Hordeum vulgare L. culture seed germination was achieved using a preparation of selenium nanoparticles stabilized by PVP C15 (8 ± 2 kDa) and ascorbic acid at a concentration of of 4.65 µg/mL. Analysis of the results showed that selenium in the form of nanoparticles has an order of magnitude that is less toxic than in the form of selenous acid. The study of morphological and functional parameters during the germination of Hordeum vulgare L. seeds allowed us to conclude that selenium nanoparticles can be successfully used in agronomy and agriculture to provide plants with the essential microelement selenium, which is necessary for the normal growth and development of crops.

Uses of Selenium Nanoparticles in the Plant Production

“…Because of their ability to influence seed growth and sowing characteristics, SeNPs are an asset in agriculture. Plants grow more resilient to drought, disease, and pests when they are exposed to their effects [52]. It has been shown in studies that SeNPs have a substantial impact on seedling germination and development early in the ontogenesis process.…”

Dynamics of Diseases of the Upper Digestive Tract in Children

“…Morbidity among the population as a whole or individual groups is a statistical indicator that characterizes the state of health of the population or the number of registered diseases per 100 thousand, 10 thousand or 1 thousand people. The main method of studying morbidity in the Russian Federation is the analysis of the population's appeal for medical care, data from professional and targeted medical examinations with the use of modern analytical high-tech equipment [20][21][22]. The morbidity indicator is used in a comprehensive assessment of the health status of the population, to justify medical and social measures aimed at improving it.…”

Application of 3D Technologies in Surgery on the Example of Liver Echinococcosis

“…Currently, there is a fairly large number of studies that emphasize the usefulness and need for the development of 3D technologies in medicine, both from an educational point of view, and for planning and surgical training [17][18][19][20][21][22][23][24]. Unfortunately, there are very few studies evaluating the anatomical features of bile and vascular changes under the influence of a parasitic cyst and the possibility of reducing intraoperative complications (wounds of liver structures, the development of bile fistulas, etc.)…”
