Resumen:
Abstract: The aims of this work were to introduce Lippia junelliana into cultivation, to compare theessential oil accumulation between cultivated and wild plants, and to reintroduce micropropagatedplants in the location of the original population. The leaves and inflorescences of cultivated plantsaccumulated, on a dry weight basis, higher amounts of essential oil than their wild counterparts. Thus,total essential oil accumulation of cultivated plant parts was also significantly higher than that of wildcounterparts. The cultivated plants showed the same essential oil profile than the wild plants. Thiswork demonstrates that cultivation can be a more efficient vehicle to both preserve and exploit L.junelliana, than collection from the wild, because higher yields of biomass and oil accumulation can beachieved, while essential oil composition is less affected by the different treatments. Thereintroduction of new plants into the species´ original location has proved to be a viable alternative fortheir in situ preservation or enrichment planting. This model of introduction of aromatic plants intocultivation through micropropagation could be a useful technique to recover valuable chemotypesfrom the wild in the search for new alternatives in the agriculture and for the preservation of naturalresources for future generations.
