Abstrakt     The response of the green alga Spirogyra sp. to different radiation environments was investigated. Samples from high elevation lakes (1669-2150 m a.s.l.) were cultured in the Ljubljana Botanical garden (320 m a.s.l.) and exposed to different levels of UV-B radiation. Biochemical and physiological analyses were made on the lake samples as well as on cultured algae. The level of UV screening compounds decreased after transferring the algae from the lakes to the botanical garden and then increased with enhanced UV-B radiation. Respiratory potential was slightly higher in UV-B treated algae. Enhanced UV-B radiation did not affect the amount of photosynthetic pigments.
