| الوصف: | The plants of Nicotiana glutinosa (L.) were hydroponically cultivated on Hoagland nutrient media supplemented by thorium, tartaric acid, putrescine and/or phosphates. The accumulation of thorium by tobacco was monitored. The effect of thorium on the photosynthetic apparatus (contents of photosynthetic pigments, rapid fluorescence PSII,) was studied. Deficiency of phosphorus in the medium caused about 10times higher Th accumulation in plants. However, the selected species – N. glutinosa does not have ability to accumulated Th enough for phytoremediation of contaminated environment. The application of putrescine on leaves lead to higher Th translocation to shoots but the effect of tartaric acid on Th accumulation was not observed. The presence of thorium in plants caused an increase in contents of photosynthetic pigments and a decrease in values of selected fluorescence parameters. Exogenous application of putrescine showed a potential in phytoremediation methods to support translocation of heavy metals to shoots. |
