| Description
| - It is expected that hydrated lichen thalli are more susceptible to negative effects of high light (HL) under low rather then optimum temperature of thallus. In our experiments, we investigated response of foliose lichen species (Lasallia pustulata) to HL stress at low temperature under laboratory conditions. Hydrated thalli were exposed to HL of 500 mmol (CO2) m-2 s-1 for 30 min under 5 oC. Response of photosynthetic parameters (Fv/Fm - potential yield of PS II photochemistry, FII - quantum yield of PS II photochemistry, qN - non-photochemical quenching, qT+I - photoinhibition-related quenching) was monitored during HL treatment and subsequent 6 h recovery in dark using chlorophyll (Chl) fluorescence imaging technique False color images of lichen thallus showing heterogeneity of the above-specified Chl fluorescence parameters over the thalli were taken using a kinetic fluorometric CCD Camera (FluorCam FL-400, PSI, Czech Republic). Subsequent image analysis allowed us to specify zones and anatomic stru

- Heterogenita fotosyntetických procesů v závislosti na navozené fotoinhibici byla studována pomocí kinetické fluorometrické CCD kamery(FluorCam FL-400) ve stélkách lasallia pustulata. Analýza obrazu umožnila rozlišit zóny stélky vykazující díky anatomickým chrakteristikám odlišnou sensitivitu vůči fotoinhibici. Na úrovni celé stélky byl zaznamenán 23 a 20 % pokles Fv/Fm and FII. Temnotní relaxace vedla k postupnému návratu obou parametrů směrem k původním hodnotám. Byla rozlišena rychlá a pomalá fáze návratu v závislosti na konformačních, respektive resyntetických procesech.
