During the past decades, agro-biodiversity has markedly declined and some species are close to extinction in large parts of Europe. Reintroduction of rare arable plant species in suitable habitats could counteract this negative trend. The study investigates optimal sowing rates of three endangered species (Legousia speculum-veneris (L.) Chaix, Consolida regalis Gray, and Lithospermum arvense L....

By quantitative techniques it has been shown that the expected tumor frequency after x-irradiation of spores of the fern Pteridium aquilinum can be reduced by the addition of casein hydrolyzate or amino acids to the medium upon which the spores are germinated and grown into either prothalli or tumors.

We investigated the responses of stomata to light in the fern Adiantum capillus-veneris, a typical species of Leptosporangiopsida. Stomata in the intact leaves of the sporophytes opened in response to red light, but they did not open when blue light was superimposed on the red light. The results were confirmed in the isolated Adiantum epidermis. The red light-induced stomatal response was not a...

Premise Recent studies of plant RNA editing have demonstrated that the number sites can vary widely among large taxonomic groups (orders, families). Yet, very little is known about intrageneric variation in frequency editing, and no study has been conducted ferns. Methods We determined plastid RNA-editing counts for two species Adiantum (Pteridaceae), A. shastense aleuticum, by implementing a p...

Adiantum capillus-veneris is important endangered fern species with several medicinal properties. In this study, the leaves samples were extracted and separated using reversed phase HPLC with DAD for carotenoids, chlorophylls and phenolic compounds. Separation of carotenoids and chlorophylls were carried out using a tertiary gradient system of water, MTBE and methanol-water, while a binary grad...
