| Description
| - Rostliny heterozygotního tabáku (Nicotiana tabacum var. xanthi) byly kultivovány v půdě získané ze skládky ve Lhenicích (jižní Čechy, ČR), která byla vysoce kontaminovaná polychlorovanými bifenyly (PCB). Celkové množství PCB v kontaminované zemině bylo stanoveno pomocí plynové chromatografie a bylo určeno v rozmezí 165 -265 mg kg-1 půdy. V roslině tabáku kultivované po 8 týdnů v této zemině bylo zjištěno množství PCB v listech v rozmezí 11-28 a v kořenech v rozmezí 104-308 mg kg-1 sušiny. Průměrná plocha listu u tabákurostoucího na zemině kontaminované PCB byla viditelně redukována a poškození DNA , měřené pomocí kometového testu, bylo nepatrné, ale signifikantní v porovnání s kontrolním vzorkem. Rosliny tabáku se zvýšeným výskytem poškození DNA prokazovaly redukovaný nárůst a měly deformované listy. Dále u těchto roslin nebylo pozorováno zvýšení frekvence somatických mutací. (cs)
- Heterozygous tobacco (Nicotiana tabacum var. xanthi) plants were cultivated in soil from a dump site highly polluted with polychlorinated biphenyls (PCBs) at Lhenice in South Bohemia, Czech Republic. The total amount of PCBs in the polluted soil, measured by gas chromatography varied from 165 to 265 mg kg-1 of soil. In tobacco plants cultivated for 8 weeks in the polluted soil the amount of PCB in the leaves varied from 11 to 28 and in the roots from 104 to 308 mg kg-1 dry mass. The average leaf area of tobacco plants growing in the PCB-polluted soil was significantly reduced and the DNA damage in leaf nuclei, measured by the comet assay, was slightly but significantly increased compared with controls. The tobacco plants with increased DNA damage showed reduced growth and had distorted leaves. No increase in the frequency of somatic mutations was detected in tobacco plants growing in the PCBpolluted soil.
