Cd、Pb单一及复合污染对花叶冷水花生长的影响及其积累特性研究
Pilea cadierei Gagnep.et Guill's Growth and Accumulation Under Single and Combined Pollution of Cd and Pb
摘要
Abstract
Using the method of pot culture, Pilea cadierei Gagnep. Et Guill was treated under the stress with single and combined concentrations of Cd and Pb. The growth changes as well as accumulation and transference of Cd and Pb were studied. The results showed the that with the increasing of concentration of Cd and Pb respectively in single treatments, the aboveground dry weight, root dry weight and root tolerance index of P. Cadierei Gagnep. Et Guill were all first increased and then decreased. The biomass of P. Cadierei Gagnep. Et Guill under different concentrations of combined treatment by Cd and Pb were lower than that of CK, and root tolerance index gradually decreased. The contents of Cd and Pb in roots, stems and leaves went up with the increasing of concentrations of the heavy metals in all treatments, and the accumulated amount in roots was higher than that in stems and leaves. Under combined treatment, the contents of Cd and Pb in different organs of P. Cadierei Gagnep. Et Guill were more than that under single treatments and the transference amount of Pb in aboveground parts of the plant had a larger increase. The results indicated that P. Cadierei Gagnep. Et Guill was a potential phytoremediation plant for combined heavy metal polluted soil.关键词
