Chlorophyll fluorescence as an indicator of fluoranthene phototoxicity

Popis výsledku v původním jazyce

The effect of the short-time exposure (12, 24 and 48 h) of increasing concentration (0.1, 1 and 10 mg/l) of intact (FLT) and photo-modified (phFLT) fluoranthene on the chlorophyll fluorescence parameters (F0, FV/FM and PhiII) in pea plants (Pisum sativumL. cv. Lantra) was investigated. Plants took up both forms of fluoranthene by two different ways, via roots or via leaves. The obtained results demonstrated a significant increase in F0 and decrease in FV/FM and PhiII in plants treated by 1 and 10 mg/lFLT and phFLT. An earlier response to presence of FLT and phFLT in the environment was demonstrated by application on cut leaves. The primary processes of photosynthesis were not significantly influenced by short-time phFLT treatment.
