    Evaluación de marcadores moleculares de cloroplasto y nucleares, para su uso en identificación molecular de germoplasmas de orquídeas
    (Universidad EAFIT, 2021) Londoño Lopera, Pablo Andrés; Villanueva Mejía, Diego Fernando
    Orchids are the most diverse and evolved group of flowering plants in the world; presenting specificity for pollination, water intake and associations with specific fungi to satisfy their nutritional needs. They are plants of great importance for the ecosystems they inhabit, since they contribute directly to its water regulation. In addition, they provide shelter and food for various organisms such as insects, birds, and mammals. Likewise, orchids are commercially important as ornamental and medicinal plants, as cut flower for export and for the extraction of essences such as vanilla. That is why when propagating and distributing them it is necessary to have them fully identified in order to adequately preserve the characteristics of the germplasms. Since it has been shown that the phenotypic characteristics are insufficient for the identification of these plants, this study was developed in order to evaluate the use of chloroplast molecular markers (MAT-K, YCF-1 and TRNL-TRNF) and nuclear (ITS) for the identification of different genera of orchids, in the seedling stage. In this research, PCR protocols were standardized for the molecular markers presented, in order to develop replicable techniques for the molecular identification of orchids. Identification at the genera level of the analyzed germplasms was carried out using the molecular marker TRNL-TRNF. In this way, scientific and technological knowledge is generated that helps the sustainable and responsible use of orchids at the national level.

    Inventario y evaluación del potencial ornamental de la familia Gesneriaceae en el Cañón del río Melcocho (El Carmen de Viboral, Antioquia, Colombia)
    (Universidad EAFIT, 2023) Peláez Vélez, Samuel; Tuberquia Muñóz, Dino Jesús; Martínez Aguillón, Camila
    The use of native plants in urban green spaces can be beneficial for local wildlife and climate resilience in cities. Despite its large plant biodiversity, there are few native species used for ornamental purposes in Colombia. Gesneriaceae is a family of plants recognized for its great ornamental potential which is highly diverse in Colombia. This study aimed to build an inventory of the Gesneriad species present in the Melcocho river basin, El Carmen de Viboral, Antioquia, and to develop and apply a method of asessment of these species’ ornamental potential. 23 species, distributed in 13 genera were found, 9 being new records for the locality. An asessment system was developed using nine criteria based in morphologic and environmental ornamental attributes, with input from six experts in the field. Eight species were valued as having a high ornamental potential, twelve were classified as having average potential and three as having a low potential. This method was succesful in prioritizing species for future ornamental and landscaping use and can be adapted to other plant groups with similar versatile habits.
