Název v původním jazyce

Effects of UV radiation and drought on the accumulation of UV-screening compounds and photosynthetic parameters in selected herbs and grasses of the mountain grassland ecosystem

Popis výsledku v původním jazyce

The main objective of the experiment conducted on a mountain grassland ecosystem was to investigate the interactive effects of UV treatment and drought on the changes in accumulation of UV-screening compounds and photosynthetic parameters in selected herb (Hypericum maculatum) and grass (Agrostis tenuis). The experimental plots were manipulated using roof constructions enabling exclusion/transmission of incident precipitation and UV radiation, respectively. Generally, UV and drought treatments had a similar effect on the accumulation of flavonols. UV exclusion resulted in a slight reduction of UV-screening compounds, particularly under the conditions of ambient precipitation. Likewise, drought treatment caused an increase in the accumulation of flavonols per area unit. Under UV exclusion, drought slightly reduced light-saturated CO2 assimilation rate (A(max)) in the both species studied. The presence of UV radiation, however, led to less of a difference in A(max) between [wet] and [dry
