ABSTRACT: Although some tree ferns can be propagated by rhizome division, the propagation method currently used is by spores. However, this method could be difficult in some cases in which environmental conditions (temperature, light and moisture) are not adequate for fern development. In the present work, 6 species belonging to 3 genera were selected: Cyathea cooperi, C. contaminans, C. tsangii, Pteris incompleta, P. cretica and Asplenium nidus, as they can be cultivated both indoors and outdoors. The germination rate of the spores of all species was high, thus producing a large number of specimens. The average duration of fern development from sowing to the end of the acclimation period was 6 months for the six species estudied. Differences among them were observed in the time of prothallus emergence and on their acclimation period. Key words:tree ferns, spores, Cyathea, Pteris, Asplenium |
