Soldanella alpina differing in leaf epidermal UV-A absorbance (DEA(375)), as measured with the Dualex, was investigated as a model alpine plant for the flavonoid (Flay) composition and concentration and for anatomical and pigment characteristics. In

Introduction The genus Soldanella is one of the few endemic to Europe. Some of its species have relevance in local traditional medicine. Earlier work has indicated the possible presence of saponins in S. alpina. Objective To investigate S. alpina and

Survival types of high mountain plants under extreme temperatures

Autor: Johanna Wagner, Christine Kainmüller, W. Larcher

Publikováno v: Flora - Morphology, Distribution, Functional Ecology of Plants. 205:3-18

Extreme temperatures are a main factor limiting plant growth in high mountain habitats. During winter, the risk of frost damage is highest at windblown and often snow-free sites. During summer, actively growing plants are particularly endangered by e
