The influence of lighting on the seeds germination of Chinese cabbage and broccoli and antioxidant activity of microgreens in the closed system of the Synergotron ISR 1.01

Relevance. Growing plants in artificial conditions (closed agroecosystems) requires precise regulation of plant growth factors, starting from the first stages of ontogenesis. One of the parameters is the presence or absence of light in the period of seed germination. For most types of cabbage the standard method is germination in the dark, but for freshly harvested seeds (at rest) light exposure is necessary. According to the literature, the mechanisms of the effect of light on seed germination are complex and ambiguous, so the issue needs detailed research. Methods. Therefore, the purpose of this work was to study the germination of seeds of broccoli (Brassica oleracea var. italica Plenck) and Chinese cabbage (Brassica rapa var. chinensis), taking into account the light factor and the simultaneous analysis of antioxidant activity as a marker of changes in metabolic processes. Results. The experiment has revealed a significant increase in the antioxidant activity of the microgreens during germination in the dark compared to germination in the light (in broccoli by 5...
