|This study examined the effect of increasing concentration (0.1, 1 and 5 mg.l-1) of Fluoranthene (FLT), an important polycyclic aromatic hydrocarbon, on plant growth, ethylene content and accompanying changes in anatomical structure of roots and stems of pea (Pisum sativum L.) after 21 days in vitro cultivation. Plant growth was negatively influenced by higher concentration of FLT (1 and 5 mg.l-1). The ethylene content is increasing proportionally with FLT concentration in the environment and higher ethylene content is responsible for presence of aerenchyma in cortex of roots and shoots.
