SUMMARY In field experiments, increase the quantum efficiency of PSII (Fv/Fp), the Rfd-values (the chlorophyll fluorescence vitality indices) and the content of photosynthetic pigments in wheat leaves at pretreatment of wheat seeds with solutions of citrate nanoparticles has been shown. Seed nano-priming can change seed metabolism and signaling pathways, affecting not only germination and seedling establishment but also the entire plant lifecycle, that the promotion of stress and diseases resistance out coming in the reduction of pesticides and fertilizers. [...]use of nano-based technology for seed treatment has big potential move to a more sustainable agriculture (Pereira E.S. et al, 2021). Iodine (I) and selenium (Se) are beneficial elements, as both play important roles in humans, that is why often using plant biofortification by agrotechnical or biotechnological approaches in order to improve, among other things, the accumulation this nutrients in food and fodder (Smoleń S. et al, 2016). [...]the aim of our work was investigation of influence of citratestabilized of nanoparticles of germanium, vanadium and selenium on photochemical activity, chlorophyll content, resistance to pathogens and productivity of plants wheat. MATERIAL AND METHODS For experiments in field conditions and in the greenhouse were used: 0.75% solutions of citrate nanoparticles Ge - GeNPs (Ge content: 500 mg/l) and citric acid; 0.75% V NPs (V content 300 mg/l) and citric acid; 1% Se NPs (Se content: 100 mg/l) and citric acid; («Nanomaterials and nanotechnology» Ltd, Ukraine); 0.5% BP I-Se (a preparation of biologically active iodine in a complex with solution Se) (preparation "Jodis-concentrate plus Se") consists of purified water enriched with polyatomic ions I, 80 mg/dm3, Se citrate, intended as a biologically active food additive (SPC «Iodis», Ukraine).
