The research aimed to provide new approach for study on Camellia oleifera breeding through ion implantation biotechnology.After different doses of titanium ion were implanted into Camellia oleifera seeds,peroxidase(POD),superoxide dismutase(SOD) and electrolyte leakage rate were researched.The seminal growth state of treated seeds was also studied.The results showed that POD and SOD activity reached the peak and electrolyte leakage rate was lowest while Ti2+ ion implantation dose between 6×10 16 and 12×10 16 Ti2+ /cm 2.The resistance of...
