Influence of Iron Glycinate and Its Ultrafine Particles on the Growth and Biochemical Parameters of <i>Triticum aestivum</i> L. Seedlings

The effect of iron chelates and its ultrafine particles (UFPs) on the growth and biochemical parameters of Triticum aestivum L. plants was compared. As an example of the effect of chelates, iron glycinate was chosen, with the help of which UFPs were obtained by interacting with quercetin. The relevance of the study was the development of new types of fertilizers based on UFPs metals, characterized by higher bioavailability, which will reduce their application rates to 6.25 · 10–4 mg/l of the finished solution. UFPs of iron were obtained by the method of “green” synthesis. The confirmation of their sizes was carried out by the method of dynamic light scattering. The positive effect of UFPs on the length and biomass of shoots and wheat roots was shown, which increased these indicators relative to the control by 29, 45 and 81%, respectively. The use of quercetin as a separate supplement improved these indicators by 37% relative to the control. The possibility of using iron UFPs obtained by the method of “green” synthesis to increase stress resistance of plants is substantiated.
