Abstract
The influence of increasing concentrations (0.1, 1.0 and 5.0 mg l-1) of fluoranthene (FLT) on growth, endogenous abscisic acid (ABA) level and primary photosynthetic processes in 21-day-old pea plants (Pisum sativum L.) in vitro was investigated. Murashige and Skoog (MS) medium, with or without FLT, was enriched with indole-3-acetic acid (IAA; 0.1 mg l-1) or a combination of IAA(0.1 mg l-1) plus N6-benzyladenine (BA; 0.1 mg l-1). The level of endogenous ABA significantly increased with increasing FLT concentrations in the presence of both IAA and IAA plus BA. An increased level of endogenous ABA was observed in plants treated with IAA alone. The growth of shoot, callus and the content of photosynthetic pigments (chlorophyll a and b, carotenoids), in both IAA- and IAA plus BA-treated plants, were significantly stimulated by FLT at its lowest concentration (0.1 mg l-1) assayed in this study. However, FLT at higher concentrations (1.0 and 5.0 mg l-1) significantly inhibited all these parameters. Chlorophyll fluorescence imaging showed that FLT only at the highest concentration (5.0 mg l-1) in the presence of IAA (0.1 mg l-1) significantly increased F0, but decreased FV/FM and PhiII.
Abstract (in Czech)
Byl studován vliv zvyšující se koncentrace fluoranthenu (FLT; 0.1, 1.0 and 5.0 mg l-1) na růst, hladinu endogenní kyseliny abscisové (ABA) a primární fotochemické procesy u 21 dnů starých rostlin hrachu (Pisum sativum L.). Médium dle Murashige a Skoog (MS) s a nebo bez FLT bylo obohaceno kyselinou indolyl-3-octovou (IAA; 0.1 mg l-1) nebo kombinací IAA(0.1 mg l-1) a N6-benzyladeninu (BA; 0.1 mg l-1). Růst nadzemní části, kalusu a obsah fotosyntetických pigmentů (chlorofyly a a b, karotenoidy) u rostlin kultivovaných v přítomnosti IAA i IAA+BA byl signifikantně stimulován FLT v jeho nejnižší použité koncentraci(0.1 mg l-1). Fluoranthen ve vyšších koncentracích (1.0 and 5.0 mg l-1) významně inhiboval všechny sledované parametry. Metoda zobrazení fluorescence chlorofylu ukázala, že FLT pouze v nejvyšší koncentraci (5.0 mg l-1) v přítomnosti IAA (0.1 mg l-1) významně zvýšil F0, ale snížil FV/FM a PhiII.
