Para ello se recolectaron ejemplares y esporas de cada taxón en el campo, las esporas se sembraron en cajas de Petri que contenían agar y medio nutritivo de Thompson, se cultivaron en germinadoras bajo condiciones controladas de luz (12hrs luz/oscuridad), humedad (50 %) y temperatura (18 °C noche y 25 °C día); se realizaron observaciones de material fresco y se tomaron fotomicrografías utilizando un microscopio óptico y un microscopio electrónico de barrido. Como resultado se distinguieron dos tipos de germinación Gleichenia y Cyathea. En cuanto al desarrollo protálico, se observaron tres tipos, Marattia, Osmunda y Drynaria. Debido a las variaciones en el tipo de germinación que no habían sido reportadas para la familia en la literatura, así como por la heterogeneidad presente en el patrón de desarrollo protálico y la presencia de más de cuatro células en los gametangios, es importante ampliar el estudio de otras especies para determinar el valor taxonómico de las características morfológicas de los gametofitos, así como para determinar si estas variaciones se presentan en otras especies de la familia.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[AbstractIn Mexico, the Gleicheniaceae family is represented by different species such as Dicranopteris flexuosa, Diplopterygium bancroftii, Gleichenella pectinata, Sticherus bifidus, S. brevipubis, S. palmatus and S. underwoodianus. Currently, few studies have described the gametophytes of some species in this family, and our objective was to contribute to the knowledge, and to describe and compare different aspects of their germination, gametophyte development, and to determine if the prothallus characters are useful for taxonomic delimitations in the group. For this purpose, specimens and spores of each taxon were collected in the field, spores were sown in Petri dishes containing agar and Thompson nutrient medium, and grown in a plant growing chamber under controlled conditions of light (12 hr light/darkness), (50 %) humidity, and temperature (18 °C night, 25 °C day). Additionally, observations of fresh materials were made and photomicrographs were taken using both optical and scanning electron microscopes. Our observations allowed distinguishing two types of germination Gleichenia and Cyathea; and three types of prothallial development Marattia, Osmunda and Drynaria. Gametangia presented more than three cells, and this is considered a primitive feature by other authors. As some variations in the germination type were observed and have not previously been reported in the literature for this family, and because of the heterogenity in the patterns of the prothallial cell development, and gametangia of more than four cells, it is important to broaden the study to other species, in order to determine the taxonomic value of the morphological characters of the gametophyte, as well as to determine if these variations are present in other species of the family.
