| 摘 要： | 转基因植物生理生态已成为当前的研究热点,外源基因的导入可能会造成许多无法预料的结果。文章借助ICP-MS/ICP-AES技术对我国自己研制的转基因棉花和对照种子中的矿质元素和重金属进行了研究。结果显示,转基因棉花种子中,所测量的15种矿质元素含量有12种显著低于非转基因对照,说明转基因棉花种子吸收和累积矿质元素的能力下降;而只有镁、铁、铜含量高于对照。在测定的九种重金属(有害元素)中有七种转基因抗虫棉高于对照,特别是铝和砷的含量高出许多甚至上百倍,而铬和汞两种重金属含量明显低于对照。

| Abstract: | With the rapid development of transgenic cotton, people begin to focus on its physiology and ecology. The present paper studied the contents of heavy metals and microelements in transgenic cotton seeds by ICP-MS/ICP-AES. The results showed that the content of most microelements detected in transgenic cotton seeds, B, Na, Si, P, K, Ca, Mn, Co, Ni, Zn, Se and Mo was lower than that in regular cotton seeds, except Mg, Fe and Cu. And the content of most heavy metals detected in transgenic cotton seeds, Al, As, Cd, Sb, Tl, Pb and Bi, was higher than that in regular cotton seeds, except Cr and Hg. All the data showed that the accumulation of heavy metals and microelements in transgenic cotton seeds is disadvantageous to itself. |
