Spores germinated10 days after sown, and cultures reached a low percentage of germination (1 to 5%). Filamentousphase was initiated at 15 days. Gametophytes followed the Aspidium type of development, whichleads to a hairy adult state, with cylindrical, marginal and superficial hairs. The morphological studyof the sporophyte was based on foliar architecture, indument, epidermal patterns of pinnulae and indusium,spore size (mean values between 28.9 and 39.7 µm) and spore morphology. Gametic chromosomenumber found was n = 72. Morphological and palynological characters of A. dareoides do not supportthe close relationship with A. flabellifolium, recently suggested from molecular data. 2007 artículo científico 0011-6793 https://www.redalyc.org/articulo.oa?id=66945102 en http://www.redalyc.org/revista.oa?id=669 Darwiniana application/pdf Instituto de Botánica Darwinion Darwiniana (Argentina) Num.1 Vol.45 |
