Abstract:

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 6×1016 and 12×1016 Ti2+/cm2. The resistance of no-sprouting Camellia oleifera seeds was stronger than that of sprouting seeds, so they could be influenced by Ti2+ ion implantation less. Sowing result showed that the survival rate of treated seeds could be guaranteed while the implanted doses were lower than 12×1016 Ti2+/cm2. The moderate doses could promote growth.
