| Abstract: | Objective] The research aimed to study the physiological and ecological characteristics of the transgenic cotton. Method] By using ICP-MS method, contents of rare earth elements in Bt transgenic and regular cotton seeds were determined. Result] The contents of rare earth elements in Bt transgenic cotton seeds, La, Ce, Pr, Nd, Sm, Eu, Gd, Dy and Ho were 7.40, 14.97, 1.47, 6.34, 0.87, 0.24, 0.91, 0.59, 0.12 ng/g respectively, and were all higher than those in regular cotton seeds. Conclusion] The accumulative capability to rare earth elements of Bt transgenic cotton seeds increased, and the need to Bt transgenic cotton seeds developed. |
