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.

Highlights

The applications of nanotechnology are becoming more widespread in various industries
When used in real environments, such particles undergo processes of aggregation, coagulation and sedimentation, with the subsequent loss of their selenium particles, and the potential forming layer is formed by the NH+ groups of the PVP C15 pyrrolidone ring (8 ± 2 kDa), which is confirmed by the study of the ζ-potential, the value of which was +58.56 mV
The anti-ion layer consists of oxalic acid ions, which are obtained via the oxidation of ascorbic acid (Figure 1B), and non-reacting ascorbic acid ions, taken in excess to form a preparation with increased antioxidant properties

Summary

Introduction

The applications of nanotechnology are becoming more widespread in various industries. The research and development of high-performance nanostructured adsorbent sensors for selective detection of trace elements and heavy metals in various media and materials used in agriculture is promising [1,2,3,4,5,6,7,8,9]. Another promising area is the use of nanoparticles to improve the productivity of crops [10,11] and the production of seed dressing agents [4,12,13]. It has been suggested that metal nanoparticles can neutralize various toxic substances in the soil [14,15,16]
