Abstract:
      The research was conducted to investigate the responses of N+ implantation on the growth and nutritional components of Medicago sativa. The results showed that the germination percentage, root length, and the contents of amino acids and nutritional components of Medicago sativa were improved with the increase of N+ ion implantation in the range of 02.08×1016/cm2; the content of protein and 100-seedling weights were improved with the increase of N+ ion implantation in the range of 01.04×(1016/cm2;) but the content of chlorophyll was decreased with the increase of N＋ ion implantation. There was a seedling of mutation under 6.76×1016/cm2. It may provide a scientific basis for transformation of Medicage sativa mediated by low energy ion beam implantation.
