日本将使用回旋加速器产生的离子束照射花卉种子，引起基因突变，培育新的花卉品种。据有关新闻媒体报道，这一研究将以菊花、杜鹃花和茶花等为实验对象，目的在于培育颜色新奇和大花的品种。 离子的速度为光速的７０％～８０％。日本已经有应用离子照射使植物叶子发生变异的研
Japan will use cyclotron ion beam irradiation flower seeds, causing mutations, cultivate new varieties of flowers. According to the news media reports, the research will be chrysanthemums, azaleas and Camellia as the experimental object, the purpose is to cultivate a variety of color novelty and large flowers. The speed of ions is 70% ~ 80% of the speed of light. Japan has been applied ion irradiation plant leaves of the mutation research
