description |
Ex-situ seed conservation is one of the most effective tools for biodiversity and genetic diversity protection. In the context of global climate change, ex situ conservation has become an important strategy that must be strengthen and integrated with in situ conservation strategies. The main objective of this study was to document the desiccation tolerance and germination properties of four species from Puya and provide tools that allow the ex situ conservation of this and other closely related species. These species are distributed in Páramo, a threatened ecosystem despite of its value as a water reservoir and supplier for urban population. Seed morphological variables and moisture content (MC) were measured before a test of germination was conducted with three different moisture contents (fresh seeds, 10–12 % and 3–5 %). Germination percentage and the mean germination time were evaluated. The germination was above 80 % in all the species with no significant differences when decreasing MC. There were no significant differences in mean germination time. Seed viability for the four species was high, as compared to other Páramo species. The results indicate that all species are orthodox. Therefore, this genus has great potential to be conserved in seed banks, which will contribute to diversity conservation of native species from tropical Andean highlands, and can be implemented in germination protocols for their propagation and reintroduction in restoration programs. |

En el marco del cambio climático su aplicación es una estrategia importante que se debe fortalecer e integrar con la conservación in situ. El objetivo del presente trabajo fue estudiar la tolerancia a la desecación y la germinación de cuatro especies del género Puya y proporcionar herramientas para su conservación ex situ. Estas especies están distribuidas en el páramo, un ecosistema amenazado a pesar de su valor como reservorio y proveedor de agua para la población urbana. En las semillas se realizó la toma de medidas morfológicas y del contenido de humedad (CH), se realizaron ensayos de germinación en tres contenidos de humedad (semillas frescas, 10–12 % y 3–5 %) y se evaluó el porcentaje de germinación y tiempo medio de germinación. Se registró una germinación superior al 80 % en las cuatro especies y no se encontraron diferencias significativas al disminuir el CH. El tiempo medio de germinación no varió entre especies y la viabilidad fue alta comparada con otras especies de páramo. Los resultados indican que son semillas ortodoxas y las variables morfológicas apoyan esta tendencia. Por tanto, este género presenta un gran potencial para ser conservado en bancos de germoplasma lo que contribuye a la conservación de su diversidad, con las cuales se pueden implementar protocolos de germinación para la propagación y reintroducción en programas de restauración.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Instituto de Ciencias Naturaleshttps://revistas.unal.edu.co/index.php/cal/article/view/67740Universidad Nacional de Colombia Revistas electrónicas UN CaldasiaCaldasiaCalderón-Hernández, Manuela and Pérez-Martínez, Laura Victoria (2018) Seed desiccation tolerance and germination of four Puya (Bromeliaceae) high-andean tropical species from Colombia.
