Ex situ phenological behavior of Lippia integrifolia "incayuyo" (Verbenaceae) from a population with a broad genetic base

Abstract

Lippia integrifolia "incayuyo" is an aromatic, sub-woody shrub used in popular medicine, aperitit drinks and compound herbs. Its choleretic, antispasmodic, biocidal, antibacterial and larvicidal activity has been proven. The objective of the work was to register the phenology of a sample of 70 genotypes from a population with a broad genetic base. The phenophases studied were: vegetative growth, flower bud, flowering and fruiting fortnightly for two years. The initiation, intensity and prolongation of the phenophases were evaluated. The moment of full bloom occurs during the second half of December. Taking this date as a reference, a differentiated beginning of flowering was evidenced. The results of two campaigns were compared, observing that 70% of the specimens had a similar behavor, standing out some genotypes for presenting an early flowering and longer duration. The recorded variability suggests that much of it could be due to intrinsic factors of the plant, and therefore, feasible to be selected.
