I used
Vaccinium vitis-idaea (pounds 6.99) because of its attractive berries and flowers.
Determination of arbutin in the herbs of
Vaccinium vitis-idaea L.
25 One very common plant community in Finland's tundra is formed by dwarf birch (Betula nana), identified by its reddish leaves in the photo; cowberry (
Vaccinium vitis-idaea), shown with its red berries; and reindeer moss (Cladonia), seen in this photo taken in autumn.
We assumed that Rubus chamaemorus and Andromeda polifolia resemble Vaccinium vitis-idaea in having negligible secondary growth (Shaver 1986), and excluded those shrub species from our estimate.
However, Betula nana, the overstory deciduous shrub, responded positively to the greenhouse treatment while Vaccinium vitis-idaea, the understory evergreen shrub, responded negatively to the treatment.
Our study suggests that tree islands and krummholz are creating safe sites for several plant species: moss, Vaccinium uliginosum, Andromeda polifolia, Salix lanata, and
Vaccinium vitis-idaea near Churchill, and
Vaccinium vitis-idaea and lichen in the Mealy Mountains.
Comments: Lingostem is a stem cell culture derived from the
Vaccinium vitis-idaea (Lingonberry or cowberry).
