The Spread of Heather, Calluna Vulgaris (l.) Hull, into Indigenous Plant Communities of Tongariro National Park
The vegetation of 10 quadrats from each of 26 sites, in and around the Tongariro National Park, which contained the introduced dwarf shrub, Calluna vulgaris (L.) Hull, was analysed using Reciprocal Averaging and Indicator Species Analysis. Six major plant communities were recognised and related to previous mapping units: tussockland with shrubs and herbs (red tussock tussockland); heathland wit...
متن کاملIn vitro activity of heather [Calluna vulgaris (L.) Hull] extracts on selected urinary tract pathogens.
Calluna vulgaris L. Hull (Ericaceae) has been used for treatment of urinary tract infections in traditional medicine. In this study we analyzed in vitro antibacterial activity of the plant extracts on different strains of Escherichia coli, Enterococcus faecalis and Proteus vulgaris, as well as the concentrations of total phenols and flavonoids in the extracts. Minimum inhibitory concentration (...
متن کاملResistance of heather plants (Calluna vulgaris L.) to cesium toxicity
Natural soil Cs concentration is low and non-toxic to plants. The stable isotope Cs is present at concentrations close to 25 μg per g of dry soil [23] and only specially Cs-rich pollucite might cause environmental toxicity of Cs, as in areas of Manitoba [20]. Additionally, two radioisotopes of Cs, Cs and Cs, originating from industry, testing of thermonuclear weapons and from radiation accident...
متن کاملGrowth and morphology of three forest understorey species (Calluna vulgaris, Molinia caerulea and Pteridium aquilinum) according to light availability
Calluna vulgaris, Molinia caerulea and Pteridium aquilinum are three forest understorey species that compete with tree seedlings for environmental resources. Forest managers therefore seek to control their growth, which is driven in part by the light available in the forest understorey. An experiment was set up in a nursery in which the three understorey species C. vulgaris, M. caerulea and P. ...
متن کاملIsolation of an active glucoside in bracken fern, Pteridium aquilinum.
An active glucoside that enhanced release of histamine from rat peritoneal mast cells was isolated from a toxic fraction of bracken fern, Pteridium aquilinum, by partition column chromatography on Sephadex G-25. It was a yellowish amorphous powder on freeze-drying, readily soluble in water or ethanol, and insoluble in ether. It was hydrolysed with beta-glucosidase to release D-glucose. It was a...
