Root response in Pisum sativum and Zea mays under fluoranthene stress: Morphological and anatomical traits

Popis výsledku v původním jazyce

Introduced organic pollutants in all ecosystem compartments can cause stress resulting in a wide range of responses including different root development. In this study, the effects of a polycyclic aromatic hydrocarbon fluoranthene (FLT; 0.1, 1 and 7 mg/L) on the growth, morphology and anatomical structure of roots of pea and maize was evaluated. In comparison with pea, significant stimulation of root system growth of maize caused by 0.1 mg/L (total length longer by 25%, number of lateral roots by 35%) and its reduction (total length by 34%) already by 1 mg/L FLT is the proof of different interspecies sensitivity to low and higher environmental loading. Nevertheless in both plant species a high loading 7mg/L FLT significantly reduced both growth (totallength by 95% in pea, 94% in maize) and the number of lateral roots (by 78% in pea, 94% in maize). Significantly increased thickness of root of both maize and pea was caused by 7 mg/L FLT and in maize already by 0.1 mg/L FLT.
