Different levels of irradiance and plant regulators modify the leaf structure and essential oil production of Lippia origanoides H.B.K (Verbenaceae)

January 2023

The quality and quantity of secondary metabolites produced by plants can be influenced by biotic and abiotic factors, since the biochemical and physiological processes that coordinate the synthesis of these compounds are influenced by these. Plant regulators can also interfere with plant growth and terpene biosynthesis in aromatic species, which is why they are widely used in agriculture. Lippia origanoides H.B.K is an...
