Abstract

Spores from two diploid taxa, Asplenium onopteris L. and A. cuneifolium Viv., and two allotetraploid taxa, A. adiantum-nigrum L. var. adiantum-nigrum and A. adiantumnigrum var. silesiacum (Milde) Viane & Reichstein, were cultured in three different types of soil. Except for A. cuneifolium, the spores germinated after ten days. The general pattern of development for the gametophytes was similar in all four taxa, following the Aspidium-type. We found that the length and density of marginal hairs differ at the specific level. The formation sequence of the gametangia studied in the three Iberian taxa was the same, and is independent of the soil type. Our results indicate that the spores in this group of taxa are able to germinate and develop mature gametophytes in different kinds of soil, and that they can produce sporophytes.
