“…It is usually propagated through seeds. However, due to its irregular germinative capacity and latency, in vitro multiplication methods using embryos are employed [71]. Based on studies conducted on various forest species, DKW medium supplemented with BAP and TDZ has demonstrated an increase in the number of shoots [26].…”

Human society is currently facing a growing demand for forest resources, which causes overexploitation and endangers biodiversity. In this regard, it is important to be aware that 10% of trees across the world are used in traditional and modern medicine. South America has the greatest diversity, with 40% of tree species in the world. The aim of our review consists of the assessment of the state of the art of micropropagation through somatic embryogenesis of representative medicinal trees in South America and of targeting the tree species that should be prioritized for conservation plans. From a total of 23,631 tree species from Central and South America, 31 are extinct, 7047 are threatened, and 1434 are possibly threatened. In this sense, in order to conserve them, various strategies are applied both in situ and ex situ. The application of in vitro multiplication protocols represents effective ways both in conservation and in the sustainable use of resources in order to obtain secondary metabolites of interest. Somatic embryogenesis is a well-known method in woody multiplication. According to the VOSviewer analyses, very few studies were available concerning aspects of somatic embryogenesis in medicinal trees. From the 10 representative species selected in our study, somatic embryogenesis protocols were established for 3 species, only for conservation purpose, not for secondary metabolites production. The development of protocols focused on obtaining secondary metabolites of medicinal trees will allow for the obtainment of valuable plant material as a non-invasive alternative.

Las especies de la familia Juglandaceae han evolucionado desde hace 56 millones de años, distribuyéndose por todo el mundo. Juglans neotropica es originaria de América del Sur y se encuentra entre 1800 m y 2800 m de altitud, en bosques secos y húmedos montanos bajos. Es una especie de hojas compuestas alternas, monoica, con polinización cruzada y anemófila, dispersada por animales y el agua, con reproducción anual. Actualmente, está catalogada en peligro de extinción (EN A2cd), ya que 52% de sus poblaciones es sobreexplotada con fines maderables. Los usos de la especie la hacen promisoria; su madera es una de las más valiosas del mundo pues en todas sus partes se han encontrado sustancias activas con potencial para la agroindustria textil, la medicina, como alimento humano; se ha usado como una excelente fuente de leña en zonas rurales. Esta especie es clave en la adaptación ante el cambio climático por sus servicios ambientales en la recuperación ecológica de suelos degradados y por mantener la calidad del aire y el agua bajo sistemas agroforestales que al mismo tiempo son un hábitat y fuente de recursos alimenticios para la fauna silvestre. También es importante como ornamental en paisajes andinos urbanizados. Por lo anterior, se hace una propuesta de propagación, como medida de conservación en zonas andinas, con base en los estudios documentados para la especie.
