Spore capsules of four Sphagnum species were buried at different depths in peat on a bog.
Spore viability was determined after 0, 1, 2 and 3 yr. Viability generally declined with time …

Some members of the monilophytes, an ancient plant group with worldwide distribution,
show significant population decline which is frequently correlated with the vulnerability of …

MATERIALS AND METHODS Soil samples were taken from 54 sites: 25 in Duke Forest,
Durham, North Carolina; 2 in an abandoned field at Pittsboro, Chatham County, North …

Desiccation tolerance is a wide-spread phenomenon in the plant kingdom, particularly in
small propagules lacking own root or rhizome system, such as seeds, pollen, spores of …

Spore germination of five globally threatened fern species [Culcita macrocarpa C. Presl,
Dryopteris aemula (Aiton) O. Kuntze, D. corleyi Fraser‐Jenkins, D. guanchica Gibby and …

Thirty-three species of ferns with nonchlorophyllous spores and five species with
chlorophyllous spores were studied in regard to their ability to survive exposure to liquid …

Ferns are a diverse and important group of plants, but diversity of species and populations
are at risk from increasing social pressures, loss of habitat, and climate change. Ex situ …

Tests were conducted to evaluate the effects of various sterilization procedures on spores of
Cyathea delgadii stored under different conditions with the intent of develo** a strategy of …

Some fern species form spore banks—reservoirs in the soil of viable spores which remain
dormant while buried but germinate in light if brought to the surface. The recently discovered …

Ex situ conservation of ferns may be accomplished by maintaining the viability of stored
spores for many years. Storage conditions that maximize spore longevity can be inferred …
