Ontogenia de los estróbilos, desarrollo de los esporangios y esporogénesis de Equisetum giganteum (Equisetaceae) en los Andes de Colombia

Abstract: Estudios sobre la ontogenia del estróbilo, los esporangios y la biología reproductiva de Equisetum son escasos, por lo tanto, para la especie E. giganteum, se estudiaron estos aspectos en especímenes recolectados a orillas del Río Frío, Santander, Colombia (2 200m). Los estróbilos en diferentes etapas de maduración fueron fijados, deshidratados, embebidos en parafina, seccionados en micrótomo rotatorio y teñidos con safranina O-fast green. Las observaciones se efectuaron mediante un microscopio óptico de alta … Show more

“…The general cell divisions in this study are consistent with the previous reports (Wilson, 1958b(Wilson, , 1999Brown and Lemmon, 1980;Rincón Barón et al, 2011;Long et al, 2016). However, the cell wall of the tapetum and the spore mother cell degraded during meiosis, which makes the actual behavior of these layers difficult to recognize in the sections of the previous investigation (Wilson, 1958b).…”
