Selection of Tolerant Plants of Cu and Ni and the Enrichment Mechanism

Abstract:

The experiment was conducted to select Pteris cretica ecergemiensis with fast growing and high enrichment of heavy metals among twenty plants and to evaluate its rule in accumulating Cu and Ni and the biological and biochemical functions using the solution culture method. The results showed that: (1) The Pteris cretica ecergemiensis had a good growth, and a high ability to accumulate the Cu and Ni with the interction effects of Cu and Ni. (2) With the increase of Cu and Ni concentration, the activities of SOD and CAT increased at first and then reduced, and the proline content increased. In conclusion, the Pteris cretica ecergemiensis is one of potential species for the great remediation of heavy metal pollution.
