| Description
| - byly studovány fotosyntetické procesy různých druhů lišejníků. In situ fotosyntéza foliózních lišejníků (Pn) dosahovala hodnot1-2 mmol (CO2) m-2 s-1 pro plně hydrované stélky Umbilicaria antarctica. Sensitivita vůči fotoinhici byla sledována pomocí dynamiky Fv/Fm. Byla potvrzena vnitrostélková variabilita tohoto parametru pomocí Chl fluorescence imaging. V průběhu fotoinhibice, byl zaznamenán nárůst NPQ a zeaxantinu. za stresových podmínek simulované dehydrace byly souběžně sledovány a korelovány primární (fluorometricky) a sekundární (oxymetricky) procesy fotosyntézy.

- Introduction Majority of lichens are capable to cope with extremes and rapid fluctuations in environmental factors, availability of water, light, and air temperature in particular. Photosynthesis in lichens is controlled by these factors and actual rate of photosynthetic processes reflects their interactive effect. Material and Methods To study lichen photosynthesis both in situ (mainly maritime Antarctica) and in a laboratory, fluorometric and gas exchange methods were used. In addition, spectral reflectance, photosynthetic pigments and antioxidants analyses, oxymetric evaluation of photosynthesis in photobionts, anatomic studies were applied in Lasallia pustulata, Umbilicaria hirsuta, U. antarctica, and U.decussata. Results and discussion Temperature response curves revealed that primary processes of photosynthesis (Fv/Fm - capacity of photochemical reactions in photosystem II, FII - quantum yield of PS II) had optimum at 18-22 oC, and hold high level (about 80 % of maximum) within the range of -5 t
