The movements of spermatozoa of bracken (Pteridium aquilinum)
Experimental Cell Research, 1954Abstract 1. 1. The movement of bracken sperms in tap water is random, the mean square displacement being proportional to the time. 2. 2. It is known that when sperms arrive at the mucilage at the necks of mature archegonia they become immobilised; it has been found in the present work that this immobilisation is irreversible. 3. 3. Sperms

Preparation and antioxidant activity of Pteridium aquilinum-derived oligosaccharide
International Journal of Biological Macromolecules, 2013In this study, Pteridium aquilinum-derived oligosaccharides (PAO) were prepared from Pteridium aquilinum polysaccharides by hydrolysis using hydrogen peroxide and their hydroxyl radical scavenging activity was investigated. The hydrolysis process was monitored by the yield of PAO.

Isolation and division of propoplasts of Pteridium aquilinum
Plant Science Letters, 1980Abstract Methods were adapted for the isolation and culture of protoplasts from fern cells. Protoplasts isolated from mutant prothalli of Pteridium aquilinum regenerated growths identical to those from which the protoplasts were isolated.

A Study of Apospory in Pteridium aquilinum
American Fern Journal, 1949thesis on the Ferns of Quebec,7 Brother Marie-Victorin included this fern, remarking that since it occurs in Vermont almost up to the Canadian boundary, it is surely present in Quebec also. Although this was doubted by others, the fern was later discovered near Bedford, in Quebec a few miles north of the Vermont border, as reported by Mousley.8 In ...
