| description |
The family Magnoliaceae has been of great interest to scientists seeking to understand flowering plant evolution. Morphological characters have been investigated in several studies, especially in China, the country with the highest number of species. Colombia, with 36 species, has the highest number of species in South America. In spite of the family’s evolutionary importance and significant threats to species survival, information is still lacking about Colombian Magnoliaceae due to a paucity of research. In this article, the pollen morphology of fourteen Magnolia species from Colombia is described based on size, shape, apertures, exine and sculpture. Pollen grains from fresh material and herbaria collections were processed using standard acetolysis methods, and morphological descriptions were elaborated based on both light and scanning electron microscopy observations. In this study the pollen grains were considered large (from 68.2 to 115 μm in the longest axis and from 41.4 to 69.3 μm in the shortest axis), boat-shaped and anasulcate. Exine sculpture patterns such as rugulate, psilate, perforate and combinations of these types were found in the species analyzed. Although there is high uniformity in the shape of the pollen grains, some differences were found among species, not only in size but also in ornamentation. The high uniformity of pollen morphology among the Colombian species supports the most recent classification of the American magnolias. |

Los caracteres morfológicos han sido investigados en varios estudios, especialmente en China, el país con mayor número de especies. Colombia, con 36 especies, tiene el mayor número de especies en América del Sur. A pesar de la importancia evolutiva de la familia y las amenazas significativas a las especies supervivientes, todavía falta información sobre las Magnoliaceae colombianas debido a la falta de investigaciones. En este artículo se describe la morfología del polen de catorce especies de Magnolia de Colombia con base en su tamaño, forma, aberturas, exina y escultura. Los granos de polen de material fresco y colecciones de herbario fueron estudiados usando métodos de acetólisis estándar, y las descripciones morfológicas fueron elaboradas a partir de las observaciones de microscopía de luz y microscopía electrónica de barrido. En este estudio los granos de polen se consideraron grandes (de 68,2 a 115 μm en el eje más largo y de 41,4 a 69,3 μm en el eje más corto), en forma de barco y anasulcado. En las especies analizadas se encontraron patrones de escultura en exina tales como rugoso, psilado, perforado y combinaciones de estos tipos. Aunque existe una gran uniformidad en la forma de los granos de polen, se encontraron algunas diferencias entre las especies, no sólo en tamaño sino también en ornamentación. La alta uniformidad de la morfología del polen entre las especies colombianas apoya la clasificación más reciente de las magnolias americanas.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Instituto de Ciencias Naturaleshttps://revistas.unal.edu.co/index.php/cal/article/view/64315Universidad Nacional de Colombia Revistas electrónicas UN CaldasiaCaldasiaSerna-González, Marcela and Velásquez-Ruiz, César (2017) Pollen of colombian magnolias.
