- Abstract
The main focus of the study was to determine the content of phenolic acids, flavonoids, and organic acids in the flowers of Tagetes patula 'Petite Gold' and 'Petite Orange'. The growth of the plants was assessed depending on the cultivation conditions. The above plants were illuminated with white light, whereas the 'Petite Gold' ones with white light enhanced with blue or red light. Both cultivars grew in a two-level-mineral compounds organic substrate. The research showed that the French marigold flowers were rich in phenolic compounds and organic acids. The 'Petite Gold' flowers had more bioactive compounds compared with the 'Petite Orange' flowers. Three flavonoids, 10 phenolic acids and seven organic acids were found in the 'Petite Gold' flowers. The artificial lighting used during the cultivation of the plants showed diversified influence on the content of organic compounds in their flowers. The measurements of the plants' morphological traits and the number of inflorescences showed that illumination with red light resulted in a better effect. Large plants with numerous inflorescences grew in the substrate with a lower content of nutrients.
