The strain 3011 was treated in 'f/2' based culture medium containing glycerine (5%, 10%, 15%, 20%) or DMSO (0.5%, 1%, 2%, 4%) as the protective additive and the protective effect was the best with 10% glycerin. With the implantation of N+, the survival rate of strain 3011 declined at the first until the N+ dose increased to 9.1×1014 ions/cm2, i.e. the survival rate of strain 3011 got down rapidly with the increase of N+ dose; but when N+ dose increased from 9.1×1014 to 1.872×1015 ions/cm2, the survival rate went up with the increase of N+ dose, but was much lower than that in control (vacuum, without N+ implantation, 100% survival rate); when N+ dose increase to over 1.872×1015 ions/cm2, the survival rate began to decline with the N+ dose increase. So, the survival rate curve shows 'saddleshaped', which is much different from the 'shouldershaped' one or 'straightlineshaped' one by γray, ultraviolet ray or other radiation sources. The purpose of this study is to research the possibility of ion beam implantation used in plasma modification of marine organisms and to provide reliable basic data on that. </em></p><p
