Description The effect of increasing concentration (0.01, 0.1, 1 and 5 mg/l) of intact fluoranthene (FLT) and photomodified fluoranthene (phFLT) on germination and root and shoot elongation in pea plants (Pisum sativum L., cv. Garde) was investigated. The obtained results demonstrated, that all applied concentrations of intact and especially photomodified FLT affected the germination and the root and shoot elongation of pea plant seedlings. Photomodified FLT appeared to be more toxic than the intact FLT. The higher concentration 1 and 5 mg/l of FLT and especially phFLT significantly inhibited the germination of pea plants. Fluoranthene 1 and 5 mg/l caused significant inhibition of the length of root while the length of shoot was affected only by 5 mg/l FLT. Concentration 1 and 5 mg/l of photomodified FLT significantly affected the length of both root and shoot.
