Morphogenesis of the gametophytes of eight Mexican species of Blechnum (Blechnaceae)
A comparative study of the gametophytes of eight Mexican species of the genus Blechnum (Blechnaceae) is described. Fertile plants for spore collection were obtained at different Mexican localities. The spores were sown in agar enriched with Thompson media and cultured at 22-25 °C, with a light regim...

| description | A comparative study of the gametophytes of eight Mexican species of the genus Blechnum (Blechnaceae) is described. Fertile plants for spore collection were obtained at different Mexican localities. The spores were sown in agar enriched with Thompson media and cultured at 22-25 °C, with a light regime of 12 hours. Spores of all species are monolete, ellipsoidal to spheroidal, and non-chlorophyllous. Vittaria-type germination occurred after 6-14 days followed by a 2-6-cell-long filament and Aspidium-type prothallial development. Adult gametophytes are cordiform-spatulate to cordiform-reniform and have wide wings with numerous unicellular marginal and superficial hairs. Sporophytes developed only in B. occidentale and B. polypodioides. |

Las plantas fértiles para la obtención de las esporas fueron recolectadas en distintas localidades del país. Éstas se sembraron en agar enriquecido con medio nutritivo de Thompson y se pusieron a germinar temperatura de 22-25 °C y con un régimen lumínico de 12 h luz. Las esporas de todas las especies son monoletes, elipsoidales a esferoidales, no clorofílicas; presentan germinación tipo-Vittaria, filamento de 2-6 células de longitud, desarrollo protálico tipo-Aspidium. Los gametofitos adultos son cordiforme-espatulados a cordiforme-reniformes, presentan amplias alas con numerosos pelos unicelulares marginales y superficiales; los gametangios son del tipo de los helechos leptosporangiados. Los esporofitos sólo se formaron en B. occidentale y B. polypodioides.
