WebThe understanding of fern germination and establishment is required for their "ex situ" conservation. The germination of a great number of fern spores is promoted by light (Miller, 1968) and nutrients, water and mild temperatures are implicated in the growth and development of the prothallus and in sporophyte formation (Fernandez et aL, 1996 ... WebReproduction by Spores. Ferns and horsetails have two free-living generations: a diploid sporophyte generation (spore-producing plant) and. a haploid gametophyte generation (gamete-producing plant). Plants we see as ferns or horsetails are the sporophyte generation. The sporophyte generally releases spores in the summer. drumback creation
