To induce the mutations, Dr Abe bombarded germinating seeds with carbon ions for 30seconds. She then planted them in fields in Miyagi. Of 600 seeds that have undergone thistreatment, 250 thrived and themselves produced healthy seeds.
为了引发变异,阿部知子博士用碳离子轰击发芽的种子30秒,然后将其种入宫城县稻田中。在进行了上述实验的600粒种子中,有250粒成活并产出了健康的种子。
The next stage of the project, to be carried out this month, is to take 50 grains from each ofthe successful plants and repeat the process with them. The resulting specimens will then besorted and the best selected for crossbreeding, in order to concentrate desirable mutations into reproduciblelines of plants.
本周即将进行这一计划的下一步骤,用50粒成活的种子重复进行上述实验,再将产出的种子分类。为了使种子变异充分,并且适于种植生产,在宫城县盐地生长得最好的部分将再进行杂交培育。
The result, Dr Abe hopes, will be a viable salt-tolerant strain that is ready for marketwithin four years. With luck, this time, it will be a tasty one as well.
阿部知子博士希望能在四年内培育出市场需要的耐盐大米,幸运的话这一次的大米将会香甜可口。
