Resumo: ABSTRACT: Guaco is a medicinal plant species containing coumarin, a secondary metabolite whose concentration is influenced by various factors, such as the level of exposure to UVA (315-400 nm) and UVB (280-315 nm) radiation, age of the plant, and position of the storage organ in the plant. This study aimed to assess the effect of different blocking levels of UVA and UVB radiation on growth parameters and coumarin content of two guaco accessions. Treatments did not affect any of the growth parameters assessed, except leaf area. Coumarin content was higher in leaves collected from the upper canopy and with unblocked exposure to UVA and UVB.
