This study confirmed the considerable effect of polycyclic aromatic hydrocarbon fluoranthene (FLT; 0.01, 0.1, 1, 4 and 7 mg/l) exposure on the germination of seeds, growth and root morphology of seedlings in Zea mays and Pisum sativum. Seed germination was significantly inhibited at FLT 0.01 mg/l and higher in maize and at 1 mg/l and higher in pea. The amount of released ethylene after 3 days of germination was significantly increased in both species at FLT 0.1 mg/l and higher. After 7 days of seedling cultivation a significant decrease in the dry weight of roots and shoots occurred in maize at FLT 0.1 mg/l and higher while in pea similar effect was observed at 1 mg/l and higher. The total length of primary and lateral roots was significantly reduced by FLT 1 mg/l and higher in maize and by 4 and 7 mg/l in pea. The length of the non-branched part of the primary root was significantly reduced by FLT 0.1 mg/l and higher in maize and 0.01 mg/l and higher in pea. In both species the number of lateral roots was significantly increased at FLT 1 mg/l and lower and inhibited at concentrations of 4 and 7 mg/l. Fluoranthene content in roots and shoots of both species positively correlated with the FLT treatment.
