The Effect of Heavy Metal Applications (Ni,Cd and Cu) on Growth and Development of Elecampane,Groundcherry and Mullein
Eren, Abdullah | MERT, Mehmet
This study was conducted to investigatethe phytoremediation potential of Inula helenium,Physalis angulataandVerbascum thapsusspecies which are grownon nickel (Ni), cadmium (Cd) and copper (Cu) polluted soils under controlledconditions for 6 weeks. The chlorophyll levels, biomass production, heavy metal uptake and concentrations and reduced glutathione concentrations were determined. According to the level of Ni, Cd, and Cu in the test plants did not reach to toxic levels. Results showed that Physalis angulatahad the highest Ni content 253 μg plant-1with the 400 mg Ni kg-1application, the highest Cd was obtained from Physalis angulata(46.9 μg plant-1)and Verbascum thapsus(54.6 μg plant-1)with 10 mg Cd kg-1application and Physalis angulatahad the highest 304 μg Cu with the 200 mg Cu kg-1application. It can be concluded that Physalis angulataand Verbascum thapsushave potentialto clean-up Ni, Cu and Cd polluted soils.
