Past studies reveal opposite effects of elevated UV-B and temperature on plant growth and
concentrations of UV-B absorbing compounds, yet few studies have dealt with the combined …

Different environmental stress factors often occur together but their combined effects on
plant secondary metabolism are seldom considered. We studied the effect of enhanced …

This study describes the physiological responses of European beech saplings to varying
levels of UV-B radiation under natural environmental conditions and in an outdoor pot …

Reflection by waxy or resinous surface structures and hairs, repair reactions of biomolecules
and induction of different sheltering components provide the means of plant protection from …

Simultaneously with warming climate, other climatic and environmental factors are also
changing. Here, we investigated for the first time the effects of elevated temperature …

Observed and projected warming has provoked research interest on tree phenology in
relation to climate. While both ultraviolet-B (UV-B) radiation and warming has been shown to …

The activity of polyphenol oxidase (PPO) and guaiacol peroxidase (POD) and the
concentrations of chlorophylls, free polyamines and soluble proteins were determined from …

The current knowledge on conifer responses to enhanced ultraviolet-B (UV-B) radiation is
mainly based on greenhouse or growth chamber experiments of one growing season in …

The effects of enhanced UV-B radiation on three examples of European shrub-dominated
vegetation were studied in situ. The experiments were in High Arctic Greenland, northern …

In trees, the change from juvenile to adult vegetative phase can last for years. In Populus
tremula L., this phase change is characterized by a morphological change in leaf shape, as …
