Content of Selected Bioactive Substances in Dependence on Lighting in Microgreens

Abstract

Young plants, also called “microgreens”, are different kinds of vegetables, grains and herbs grown to the phenological phase of cotyledons, or to the development of the first pair of true leaves. The aim of the work was to study the influence of lighting on the young plants quality in selected 11 vegetables species. The experiment was carried out during the winter time in a heated greenhouse of the Botanical Gardens of SUA in Nitra. For the lighting there were used linear fluorescent lamps FLUORA T8 - L 36W / 77 - G13 during the whole period of cultivation. According to our results, the lighting had a positive impact on the quality of harvested plants. The higher contents of vitamin C, chlorophyll a and chlorophyll b were estimated in comparison with the control variant without lighting.
