Responses of Linum usitatissimum and Callistephus Chinensis on copper contaminated substrate
Authors: , , ,
Abstract: The phytoremediation potential of two plants Linum usitatissimum (flax) and Callistephus Chinensis (China aster) was evaluated for their ability to accumulate copper in contaminated soil substrate under laboratory conditions. The results showed that the total amount of copper was accumulated significantly more in L. usitatissimum than C. Chinensis. The maximum highest accumulation of copper in L. usitatissimum was found of 280 mg kg-1 at copper concentration 2520 mg kg-1 in soil substrate. In both plants, the roots accumulated primarily higher amounts of copper compared to the amount translocated in the shoots. Phytoremediation research also includes the assessment of copper toxicity and stress caused in plants. The physiological parameters can be used to assess copper-induced stress such as germination and biomass production. Low toxicity symptoms in L. usitatissimum are indicated as an increase in biomass production in relation to increasing copper concentration along with low sensitivity in seed germination. The toxic effects of copper in C. Chinensis include the inhibition of germination as well as the reduction of biomass production at increasing copper concentrations in soil substrate. Our results indicate that the mixed culture of L. usitatissimum and C. Chinensis can be considered effective for the phytostabilization of copper from contaminated soil with low copper concentration.
