Viability of spores of some fern species


, : Viability of spores of some fern species. Byulleten' Glavnogo Botanicheskogo Sada (138): 63-65

Spores of 10 species, including 5 Dryopteris, 3 Polystichum, Gymnocarpium dryopteris and Matteuccia struthiopteris were stored at room temperature for 1-3 years and were then grown on Knopp solution in natural light for 90 days. Germination was retained but viability was weakened.

Autopolyploidy may arise through fertilization involving gametoph...
