THE INFLUENCES OF IRRADIATION SENSITIVE AGENT ON THE BIOLOGICAL EFFECTS OF THE WHEAT IMPLANTED BY THE HEAVY IONS |
| |
| Abstract: | The influence of heavy ions(Fe 1+ at various doses) implantation on the biological effects of the wheat were studied.The spring wheat seeds of new species 81529 were implanted by Fe 1+ heavy ions produced by 200kV implantation ion installation at Institute of Modern Physics Lanzhou,and then irradiation sensitizing agent were added.The results of effects of the implantation on the wheat were as follows.(1)Chromosomal aberrant frequency was improved with increasing dose of Fe 1+ heavy ions.(2)There are different influence on germination ability and chromosomal aberrant frequency with different irradiation sensitive agent treatements.(3)The trend of chromosomal aberrant frequency influenced showed as EDTA>Colchicine>Caffeine,but the influence on germination ability are different with various dose of Fe 1+ heavy ions implanted to the wheat seed. |
