Resumen

Lantana camara (L.) is considered one of the main invasive plants, and the allelochemicals produced by this species can be defined as bioactive secondary metabolites that mediate chemical interactions between the plant and other organisms and, therefore, play an important role in its succession and establishment. The present study aimed to investigate the effect of L. camara aqueous extracts on the germination and growth behavior of Bidens pilosa (L.) by evaluating physiological parameters (germination rate, germination speed index, seedling performance and structure and membrane integrity), as well as the extract metabolic profile. The extract reduced the germination speed index and seedling growth rate and promoted abnormalities in the geotropism and root development in both populations. The third germination phase was highly affected (more than the phases I and II). Lantadene A and B are the possible compounds conferring the herbicidal properties, and the L. camara extract has a potential to be used in the development of a new environmentally-friendly herbicide.
