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 fibre by ICP-MS/ICP-AES. The results showed that the contents of most microelements (B, Mg, Mn, Fe, Co, Ni, Cu, Zn, Se and Mo) detected in transgenic cotton fibre were lower those in regular cotton fibre, especially the contents of Zn which was several times lower. But the concentrations of Na, Si, P, K and Ca in transgenic cotton fibre were higher than those of regular cotton fibre, especially for Si. The concentrations of the heavy metals detected(Al, Pb, Cr, Cd, Sb, Tl and As)in transgenic cotton fibre were all lower than those in regular cotton fibre. All the data showed that the accumulation patterns of heavy metals and microelements in transgenic cotton fibre were cianged by the insertion of foreign genes.
