Abstract

Hedeoma multifloraBenth. (Lamiaceae) is an aromatic-medicinal species native to Argentina, Uruguay and southern Brazil that is in a state of vulnerability due to overexploitation. It is used in the preparation of flavored yerba mate and in popular medicine, mainly in abdominal conditions. The objective of this work was to adjust the micropropagation technique, study the field behavior of vitroplants, compare the seeds generated and close their cultivation cycle. Different concentrations of growth regulators were evaluated on Murashige-Skoog medium. The implantation was successful. There are no differences between the evaluated plants. It was possible to efficiently close the complete cycle in vitro, with 100% survival, flowering and production of viable seeds. This methodology will serve for its introduction to the field, subsequent domestication, reintroduction into its natural environment and mitigate the process of degradation of the populations.
