Essential oil composition and antibacterial activity of Pteridium aquilinum (L.) Kuhn

Biologia Futura, 2019
Introduction The present work aims to study the chemical composition of Pteridium aquilinum (L.) Kuhn essential oil and its antibacterial activity against three important phytopathogenic Gram-negative bacteria: Erwinia amylovora, Pectobacterium ...

Pteridium aquilinum

2000
Abstract Bracken fern (Pteridium aquilinum) is a plant (family Polydodiaceae) containing thiaminase I; this enzyme causes thiamine and thiamine diphosphate depletion. Ingestion of the fern by livestock causes significant neurotoxicity, which is dependent on plant part, season, maturity of the plant, and rainfall.

Growth and mortality patterns of the Neotropical bracken (Pteridium arachnoideum) and their response to shading in a savanna–riparian forest transition

Flora: Morphologie, Geobotanik, Oekophysiologie, 2019
Although certain clonal species are often overdominant in disturbed tropical ecosystems, it is often unclear how this success is related to their patterns of clonal growth and how they respond to abiotic heterogeneity.

The movements of spermatozoa of bracken (Pteridium aquilinum)

Experimental Cell Research, 1954
Abstract 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

(‒)-Pteroside N and pterosinone, new BACE1 and cholinesterase inhibitors from Pteridium aquilinum

Phytochemistry Letters, 2018
Bioassay-guided fractionation of the ethanolic extract from the whole plants of Pteridium aquilinum has resulted in the isolation of a new pterosin glycoside, (‒)-pteroside N (1), and a new seco-illudoid sesquiterpene, pterosinone (2).

A Study of Apospory in Pteridium aquilinum

American Fern Journal, 1949
thesis 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 ...

Dihydrocinnamic acids in Pteridium aquilinum

Food Chemistry, 2005
Abstract Dihydro-p-coumaric (phloretic) and dihydroferulic acids have been identified in Pteridium aquilinum. Whereas the latter has been located in cyanogenic and acyanogenic plants, the first has only been detected in cyanogenic forms.

Isolation and division of propoplasts of Pteridium aquilinum

Plant Science Letters, 1980
Abstract 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.
