众所周知,太空育种是一个热门话题。所谓太空育种就是将种子带到太空,在微重力条件下,使其直接受到来自宇宙空间的各种辐射,最终使种子DNA断裂,回到地面时,DNA重新排列组合产生变异。我想,我们可以在地球上人工制造“宇宙射线”。利用放射性物质的放射性,如铱192,铱192可放出γ As we all know, space breeding is a hot topic. The so-called space breeding is to bring the seeds into space, under the conditions of microgravity, make it directly from all kinds of radiation from the cosmic space, and ultimately make the DNA breakage, back to the ground, DNA rearrangements and combinations of mutations. I think we can artificially create “cosmic rays” on Earth. The use of radioactive radioactive substances, such as iridium 192, iridium 192 emit γ
