Filtering out natural UV radiation below 380 nm has a distinct effect on plant growth and competitive balance between selected pairs of competing species. In all cases total biomass of both partners together was smaller under the influence of UV, in many cases also shoot length and/or leaf area. Chlorophyll content was usually greater in UV exposed plants. In Acer pseudo platanus L. the competitive balance of highland and lowland ecotype was reversed under the influence of natural UV radiation.
