Resumo: Growth, essential oil content, and content of coumarin in young plants of guaco (Mikania glomerata Sprengel) cultivated under colored nets. Mikania glomerata Sprengel is a medicinal plant widely used in folk medicine, mainly to treat respiratory disorders, which acts by dilating the bronchi, being coumarin one of the K ? T ' its responses to the environmental conditions is necessary to improve the cultivation methods. In this context, the aim of this work was to evaluate the effect of light spectrum control on growth, the essential oil content, and the content of coumarin in Mikania glomerata Sprengel. Plants were grown for four months under nets K V T ! ? K ! ' T & ' ? / K / T W 9& ?
