The effect of N+ implantation on the activities of CAT, POD, SOD, T-AOC and the capacities of scavenging O2− and OH in Blakeslea trispora (−) were studied. Results showed that N+ implantation caused different changes of CAT, POD, SOD, T-AOC activities and cell scavenging O2− and OH capacities. With the implantation dose increasing CAT activity was lower than the control sample, while POD, SOD activities and the scavenging O2− and OH capacities all decreased at the beginning, and then increased lately. At the dose of 6.0×1015 N+ cm−2 T-AOC activity was lowest, while at the dose of 1.2×1015 N+ cm−2 its activity was highest, and this change trend was same to the B. trispora (−) survival rate curve. So we speculated that the changes of these antioxidases activity of B. trispora (−) induced by low-energy N+ probably have some relationship with its “saddle shape” survival rate curve.
