Biologically active substance uses identify the most effective options for various fruits, vegetables, and green crops. The most promising silicon preparation (1-ethoxysilatrane) application as an organoelemental biologically active substance confirmed its high efficiency in producing traditional plants. Silicon preparations and organosilicon esters of triethanolamine-silatranes synthesis by Russian scientists led by M.G. Voronkov became widely used biological active substances in crop production. With an organoelemental biologically active substance, the effectiveness of the drug germanium (1-germatranol) gained scrutiny. Germatrane (RGe(OCH₂CH₂)₃N) synthesis immediately followed the preparation of silatranes; however, studying its effectiveness as phytoinducers for microgreens has just begun. The presented research comprised the technology for producing Abyssinian Niger seed plant (Guizotia abyssinica) microgreens grown in an urban-type synergotron specified conditions and climate chamber regimes with LED and fluorescent lighting using pre-sowing treatment of plant seeds with 0.001% solutions of 1-ethoxysilatrane and 1-germatranol.

Key findings: By using biologically active substances based on silicon and germanium at the stage of pre-sowing seed treatment, the biochemical composition of Abyssinian Niger seed plant microgreens (nitrogen content, chlorophyll, carotenoids, total antioxidant activity) succeeded in evaluation. Germatranol positively affected the growth dynamics of Abyssinian Niger seed microgreens, revealing 53.3% compared with the control sample. The mass indicators of microgreens treated with germatranol exceeded the control sample by 24.3%. Higher antioxidant content was evident than the control treatment for microgreens treated with germatranol (57.5%) and ethoxysilatrane (9.6%).
