Abstract: Doses of 1×1016, and 2×1016cm-2 and 1×1016, 2×1016, 3×1016 and 3.6×1016cm-2 for iron and cppper ions are implanted in dry seeds of mung bean, respectively. The results show that the accumulated-copper and -iron ion amounts in the seeds and roots vary with different doses of ion beam, and the fresh and dry weights of the roots decrease progressively with increasing iron and copper doses, except the treatment of 1×1016 Cu+ ions/cm2 and the accumulated-copper and -iron ion amounts in the seeds of the different test groups can be correlated with the ion distribution in the roots.
