Abstract

The effect of fluoranthene (FLT; 0.1, 1 and 5 mg/L) on chlorophyll fluorescence parameters (F0, FV/FM and PhiII) on foliose lichens Lasallia pustulata and Umbilicaria hirsuta and pea plant leaves during short-time (3 days) exposure was investigated. FLT induced changes in values of chlorophyll fluorescence parameters (F0 increase, decrease of FV/FM and PhiII) especially when applied in the highest concentration 5 mg/L. The response of primary processes of photosynthesis of both lichens and pea plant leaves to the presence of FLT was comparable.

Abstract (in Czech)

Byl studován účinek fluoranthenu (FLT; 0.1, 1 a 5 mg/L) na parametry indukované fluorescence chlorofylu (F0, FV/FM a PhiII) u foliózních lišejníků Lasallia pustulata a Umbilicaria hirsuta a listů hrachu (Pisum sativum) během krátkodobé (třídenní) expozice. Fluoranthen vyvolal změny v hodnotách parametrů fluorescence chlorofylu (zvýšení F0, pokles FV/FM a PhiII) zejména ve variatě vystavené 5 mg/L FLT. Odezva primárních procesů fotosyntézy obou lišejníků a listů hrachu byla srovnatelná.
