| Abstract
|
| [Objective] To determine the contents of Mn, Cu, Zn, Fe, K, Ca and Mg in velamen, stem bark and rhizosphere soil of Periploca sepium Bge. of three growth forms (vine, shrub and sprawling shrub), and study the distribution and enrichment characteristic of these elements in different fractions. [Methods] All samples were wet digested on electric heating plate, content of each element was determined by flame atomic absorption spectrometry. [Results] Contents of elements in velamen and stem bark are quite different, but all ordered as K > Ca > Mg > Fe > Mn > Cu > Zn; distribution of Zn, Fe, K and Ca were significantly different in two parts. Zn, K and Ca were more in stem bark, and Fe in velamen; contents of elements in rhizosphere soil which was excellent were ordered as Fe > K > Ca > Mg > Mn > Zn > Cu, and Cu and Ca were highly enriched, K had a certain enrichment in stem bark. [Conclusion] The foundation is laid fof improving the basic research such as ecology of Periploca sepium Bge. by making the contents, distribution and enrichment characteristic of seven elements in velamen and stem bark cleared, providing data for supporting dividing into two categories, and firstly proposing the possiblity of phytoremediation in copper contaminated soil by Periploca sepium Bge. . |
