 The researchers studied the effects of selenium nanoparticles, CERNPs, on the morphology and physiology of barley seeds. They found that CERNPs had a positive zeta potential and a size of approximately 50 nanometers. Treatment of barley seeds with CERNPs resulted in increased root length and sprouting, as well as improved germination and germinability. Additionally, no local destruction was seen at concentrations greater than 5 milligrams per liter, suggesting that the toxicity of CERNPs may be limited to the seedcote. Furthermore, the researchers observed that CERNPs induced reoriented root system growth toward thickening, indicating that they could potentially be used as a stimulant for the growth and development of crops under stress or reduced morphofunctional characteristics.
