Název v původním jazyce

Inhibitory effect of fluoranthene on photosynthetic processes in lichens detected by chlorophyll fluorescence

Popis výsledku v původním jazyce

The effect of increasing concentration (0.01, 1 and 5 mg.l-1) of fluoranthene (FLT) and the duration of exposure (12, 24, 36, 48 and 60 h) on the chlorophyll fluorescence parameters (F0, FV/FM, PhiII and (FM-FS)/FS)) of symbiotic algae in thalli of two foliose lichens Lasallia pustulata and Umbilicaria hirsuta was investigated. Also the FLT concentration in thalli of both lichen species and the proportion of symbiotic algae (photobionts) in thalli was studied. The results obtained demonstrated that theapplied concentration of FLT (1 and 5 mg l-1) affected primary photochemical processes of photosynthesis of algae in both lichen species. The F0 values increased and the FV/FM and PhiII values decreased. The fluoranthene content in thallus of both lichenspecies was increased with increasing FLT concentration in the environment. Chlorophyll fluorescence parameters showed different sensitivity to the content of FLT in Lasallia pustulata and Umbilicaria hirsuta, respectively. Higher sensit
