本世纪20年代,核技术开始应用于农业科研。由于其方法独特,手段先进,在农业领域很快地推广和普及。目前,已在育种、栽培生理、土壤肥料、食品保鲜、环境保护、畜牧业等方面广泛应用,取得了显著的成就。 1.植物育种 30年代,利用辐射育成了第一个作物突变品种烟草chlorina。1942年,Auerbach开始利用化学诱变剂诱发突变。自60年代以来,诱变育种引起了各国育种家的重视。目前,世界上已有37个国家获得了由诱变手段育成的农作物品种。据国际原子
In the 1920s, nuclear technology began to be applied to agricultural research. Because of its unique method and advanced means, it is rapidly popularized and popularized in agriculture. At present, it has made remarkable achievements in such fields as breeding, cultivation physiology, soil and fertilizer, food preservation, environmental protection and animal husbandry. 1. Plant breeding 30’s, the use of radiation bred the first crop mutant tobacco chlorina. In 1942, Auerbach began to use chemical mutagens to induce mutations. Since the 1960s, mutagenesis has attracted the attention of breeders in various countries. At present, 37 countries in the world have obtained crop varieties bred by mutagenesis.
