The effect of fluoranthene on the germination of plants

Abstract

The effect was studied of increasing concentration (10,100 and 500 ng l -1 ) of fluoranthene (FLT) in solution on the energy of germination and the germination rate of seeds of Allium cepa L., Helianthus annuus L., Lactuca sativa L., Picea abies (L.) Karst., Sinapis alba L., Solanum lycopersicum L., Triticum aestivum L., Zea mays L. The content of lipids in the seeds was determined and the effect of FLT on the uptake of water by the seeds evaluated.The obtained results demonstrated that the increasing FLT concentration inhibited the energy of germination and the germination rate of seeds of all plant species. The species studied showed different sensitivity to the content of FLT. The effect of increasing FLT concentration was reflected more conspicuously in plant species with a higher content of lipids in the seeds (Helianthus annuus L., Lactuca sativa L., Picea abies (L.) Karst., Solanum lycopersicum L.). The inhibition of germination maked deeper significantly by the application of FLT from the beginning of imbibition. In none of the plant species FLT did not affect the uptake of water by the seeds.

Effect of some new monoquaternary salts of diazine on germination and seedling growth of Norway spruce (Picea abies (L.) Karsten)

“…Such species are commercially available as herbicides and weed killers and may also be found within certain formulations for selective clearing of paths or in combination pesticides. Higher plants are recognized as excellent indicators of cytogenetic and mutagenic effects of some chemicals and are applicable for the detection of environmental noxious compounds [5][6][7]. The germination test determines the actual germination potential of normal seeds within a seed lot, which can be used to compare the quality of different lots, and also estimate the field planting value.…”
