Chromsome aberrations in cattle raised on bracken fern pasture

Experientia, 1988
Thirteen cows maintained on natural bracken fern (Pteridium aquilinum) were analyzed cytogenetically. The frequency of structural chromosome aberrations detected in peripheral blood cells was significantly higher when compared to that detected in animals raised on pasture containing no bracken fern.

Physiological requirements for ciliary reactivation of bracken fern spermatozoids

Journal of Cell Science, 1980
ABSTRACT Physiological parameters affecting reactivated ciliary beat in spermatozoids of bracken fem (Pteridium aquilinum) were studied using a Triton/glycerol permeabilized cell model system. Reactivation frequencies of polylysine-tethered cells equalled in vivo rates at neutral pH. Frequency was dependent on ATP and Mg!+ concentration,

Gametophyte formation in bracken fern root cultures

Canadian Journal of Botany, 1969
Excised roots of the bracken fern (Pteridium aquilinum (L.) Kuhn) have been continuously subcultured in various growth supporting media. The formation of gametophytes on the roots (apospory) occurs in three instances: on intact sporelings in culture, in aged growing root cultures after growth of the roots has ceased, and at an earlier time on excised ...
