长春大花君子兰各部位中28种无机元素的测定

对长春大花君子兰各部位中28种无机元素进行了测定。实验结果表明,各部位中都含有锶、铁、锌、钼、锰、铜、镍、氟、碘、铬、钴、铅、镉、汞钾、镁、钠、氯等18种元素。13种必需微量元素含量总和依叶、根、内果皮、花、外果皮和中果皮、花葶和花柄、种子顺序递减。28种元素的平均含量差异较大,同一种元素含量因部位不同差异也较大。铁、锌、锰、铜、镍、铬、钴、锶、钼、钒、钛的平均含量分别比一些中药高,而砷、铅、镉的平均含量则分别比一些中药低。各部位的Zn/Cu比值的平均值为3.01。

Determination of 28 inorganic elements in diifferent parts of Clivia miniata Changchun

Twenty-eight inorganic elements in different parts of Clivia miniata Changchun were determined. Experimental results showed that each part of the plant contained Sr, Fe, Zn, MO, Mn, Cu, Ni, F, I, Cr, Co, Pb, Cd, Hg,K, Mg, Na and Cl. There was much difference between the average contents of these 28 elements. The content of the same element in different parts of the plant also varied considerably. The sum of the contents of 13 essential trace elements, and some elements, such as Sr, Fe, Zn, Mo, Mn, Cu, Ni, F, V, I, Cr, Co, and Sn were decreasing progressively in the order of leaves, roots, endocarp, flowers, ectocarp and mesocarp, flower stems and stalks, and the seeds.The average ratio of Zn/Cu in all parts of the plant was 3.01.
