Early stages of plant ontogenesis in the environment treated by organic pollutant
Original language description
The aim of this study was to evaluate the effect of polycyclic aromatic hydrocarbon fluoranthene and its increasing concentration (0.01, 0.1, 1, 4 and 7 mg/L) on germination of seeds and production of ethylene, ethane and carbon dioxide during germination, and early growth of seedlings in Pisum sativum and Zea mays. Whereas in maize the germination was significantly lowered already by 0.01 mg/L FLT (91% germination), in pea the significant decrease in germination was found in two orders of magnitude higher FLT concentration (1 mg/L; 93% germination). This could be related to higher lipid content in maize seeds. The most significant decrease in seed germination of both plant species were found in seeds treated by 7 mg/L FLT (78% germination in maize and90% in pea). Root and shoot elongation is besides the seed germination a convenient indicator of the environmental phytotoxicity.
