Annotation	Metabolomic profiling represents a new tool to ascertain the plants response to biotic or abiotic stresses. Generally, biosynthesis and accumulation of metabolites especially polyphenols in plants is induced by enhanced UV radiation and nitrogen deficiency. However, the spectrum of polyphenols, their localizations, and dynamics of synthesis/degradation may be altered by UV:PAR ratio and C:N stoichiometry. The main objective of our work was to study how changes in UV:PAR ratio (modulated by UVA+UVB lamps and plastic filters) and N supply influence metabolic profiles in barley varieties with different sensitivity to oxidative stress. Metabolomic profiling (HPLC-MS), accompanied by physiological measurements, covered a wide spectrum of secondary and primary metabolites. Significant differences in constitutive metabolomic profiles, particularly phenolics, were observed between barley varieties. High UVA and UVB doses increased synthesisof galangin, luteolin, chrysin etc., particularly in s
