Abstract

V originále

The effect of fluoranthene (FLT; 0.1 and 1 mg/L) on chlorophyll fluorescence parameters (F0, FV/FM, and PhiII), the content of photosynthetic pigments (chlorophyll a, b and carotenoids) and Hill reaction activity in pea plants was investigated. Pea plants were cultivated hydroponically for 18 and 25 days. The results proved that FLT affected primary photochemical processes of photosynthesis in pea plants: a decrease of Hill reaction activity, increase of F0 and decrease of FV/FM and PhiII and the decrease of pigment content was recorded.

In Czech

Byl studován vliv fluoranthenu (FLT; 0.1 a 1 mg/L) na parametry fluorescence chlorofylu (F0, FV/FM, a PhiII), obsah fotosyntetických pigmentů (chlorofyl a, b a karotenoidy) a aktivitu Hillovy reakce. Rostliny byly kultivovány hydroponicky po 18 a 25 dní. Výsledky dokládají, že fluoranthen ovlivnil primární procesy fotosyntézy u hrachu: zaznamenán byl pokles aktivity Hillovy reakce, zvýšení F0 a pokles FV/FM a PhiII a také snížení obsahu fotosyntetických pigmentů.
