Recientemente ha sido publicada una nueva propuesta de clasificación las plantas vasculares sin semilla (PPG1) hasta el rango género, basada en caracteres morfológicos y filogenias moleculares, siendo consensuada por un gran número especialistas pteridología. Tras año desde su aparición ampliamente aceptada la comunidad científica. Esta presenta serie importantes cambios respecto a sistemas anteriores, entre ellos empleado para Flora Iberica I. Este trabajo plantea actualización del PPG1...
Gametophytes of the Pteridaceae are moderately well known but there is still a quite large set species to describe. Among these Doryopteris triphylla, member cheilanthoid clade (subgroup hemionitids). The main objective this work describe gametophyte D. triphylla. In vitro cultures were prepared with spores coming from various sporophytes different locations. vivo observations done periodically monitor developmental critical events and reproductive activity. Germination followed Vittaria...
Stomata are very conserved structures in plants, which allows and control the gas exchange. This ecophysiological fact appears to be critical ecology adaptation of plants environment. Plant individuals can, among other issues, adjust size density stomata adapt themselves hydric, thermic light regimes. In turn, this led reduction transpiration water losses, is crucial areas with Mediterranean climate. The fern Osmunda regalis has populations both biogeographical regions Iberian Peninsula...
En este trabajo se incluyen novedades de interés corológico sobre tres helechos que son desconocidos o escasos en la Península Ibérica. primer lugar, testimonia por primera vez presencia Polystichum braunii Por otro lado, aporta tercera localidad conocida del híbrido Asplenium × aran-tohanum. último, extiende notablemente hacia el interior peninsular distribución Struthiopteris spicant var. homophyllum.
Las plantas vasculares que no forman semillas son conocidas con el nombre vulgar de helechos, presentando unas 120 especies en la península ibérica, más abundantes ambientes forestales húmedos y saxícolas. En entornos urbanos semiurbanos suelen ser muy numerosos, un hecho parece estar unido a escasa presencia sus esporas atmósfera estas zonas, comparación otras partículas biológicas como las fúngicas o los granos polen. El objetivo este trabajo es proporcionar una clave determinación tipos...
En este trabajo se estudia la germinación, el patrón de desarrollo morfológico y expresión sexual dos especies helechos homospóreos que habitan en Chile: Pteris semiadnata Blechnum arcuatum. Para ello recolectaron esporas diferentes esporófitos sembraron cultivos agar mineral, mantenidos condiciones controladas. Los máximos porcentajes germinación observados fueron 82 91% para B. arcuatum P. semiadnata, respectivamente. El ambas corresponde con tipo Vittaria. ajusta al Aspidium....

The gametophytes of the Athyriaceae are not very well known, such as Diplazium caudatum. aim this work is to analyze gametophytic phase species, which includes germination study, morphological development and reproductive phase. Spores belonging two different sporophytes from La Gomera, Spain, were mixed sown in multisporic cultures. Plates have been cultured chambers with nutritive agar at 25ºC 12 hours photoperiod. was registered every three days, main vegetative checked throughout...
The gametophytic generation of Amblovenatum immersum and Christella subpubescens (Thelypteridaceae), including spore germination, morphological development the gametophytes, major vegetative features reproduction strategies, was studied. For both species, germination Vittaria type developmental pattern Drynaria type. Adult gametophytes were cordate hairy, with unicellular secretory hairs located in margins ventral dorsal surfaces prothalli. C. has another acicular only margin prothallus....
