| Abstract: | Seeds from transgenic Indica rice plant were treated with the different kinds, the different energy units and the different doses of ions, and the design of orthogonal experiment with three factors and three levels was adopted to search for the major acting factor among these mutant factors which affected on the ratio of alive seedling and the speed of seedling growth and also, to research on the damage efficiency of ion beam implantation on the present generation. The result indicated the energy unit of ion was the most important factor of improving the ratio of alive seedling, and low energy unit(15kev) was the most effective treatment for the ratio of alive seedling. And the kind of ion was the main effective factor affected on the seedling growth, and Ar + was the best treatment for the seedling growth. |
