Secondary plant metabolites are unique sources for pharmaceuticals, food additives and industrially important biochemicals. The accumulation of such metabolites occurs in plants affected by stress. The paper deals with the effect of abiotic stress, which caused by the spectral composition binary change of radiation produced by matrix LED light sources, to the development and production of secondary metabolites in rocket Eruca sativa with protected cultivation. The obtained results showed the dominant «blue» and «red» spectral ranges intensities correlation influence in binary switching light fluxes. The conditions were defined when the accumulation of plant biomass and the plants root system development significantly exceed control measures. The compromise was defined between the qualitative characteristics of the light flux and the inflicted binary spectral stress with an increase of the fresh mass of plants at the simultaneous synthesis of such secondary metabolites as an ascorbic acid and flavonoids.
