摘要: 采用原子吸收分光光度法测定了矮牡丹体内的10种矿质元素,即K、Mg、Mn、Fe、Ni、Zn、Cu、Cd、Cr、Pb。分析了矿质元素在矮牡丹体内的分布规律及矮牡丹对各种元素的富集能力。结果表明:在不同器官中的矿质元素含量有显著差异, K、Mg、Mn、Ni、Cd、Cr、Pb以叶中为高, Fe、Zn、Cu分别以根、茎、叶柄中含量最高;大多数元素在叶柄中含量最低。矮牡丹对K、Mg、Mn、Fe、Zn有较强的吸收富集能力,一般叶的富集系数较其它器官为高。元素间相关分析表明:Zn、Cd、Cr、Pb、Mn、Fe、Ni、Cu之间有显著的相关性, K、Mg之间的相关性显著。此外,土壤与植物体内元素含量表现出显著的相关性。

Abstract: kinds of mineral elements(Cd, Cr, Mn, Ni, Pb, Cu, Fe, Zn, K and Mg) of Paeonia suffruticosa var. spontanea in Jishan, shanxi province were determinated by atomic absorption spectroscopy, the distribution characteristics and the accumulation index were also investigated in this paper. The results shows that there is evident difference of the mineral elements in different organs. The contents of K, Mg, Mn, Ni, Cd, Cr, Pb are higher in leaves and Fe, Zn, Cu are higher in root, stem and petiole. Majority mineral elements are minimum. On analyzing the concentration factor of all the elements, the concentration factor of K, Mg, Mn, Fe, Zn are higher in Paeonia suffruticosa var. spontanea, the concentration factor of leaf were higher than other organs. the correlation among Zn, Cd, Cr, Pb, Mn, Fe, Ni and Cu were statistically significant. In addition, relationship between all the elements were studied by means of correlation analysis. The results are as follows:There are significant correlation among Zn, Cd, Cr, Pb, Mn, Fe, Cu and Ni, and the correlation were statistically significant between K and Mg. Moreover, There existed a significant correlation between the elements in soil and plant.
