经历过太空遨游的农作物种子,返回地面种植后,不仅植株明显增高增粗、果型增大、产量比原来普遍增长,而且品质也大为提高。太空环境对植物基因产生影响虽已得到各国科学家的证实,但对太空育种原理的解释仍在争论之中。科学家认为,太空育种主要是通过强辐射、微重力和高真空等太空综合环境因素诱发植物种子的基因变异。由于亿万年来地球植物的形态、
After experiencing space travel of crop seeds, returning to the ground after planting, not only significantly higher plant thickening, fruit-type increases, the general increase in output than the original, but also greatly improved the quality. Although the impact of space environment on plant gene has been confirmed by scientists from all over the world, the explanation of the principle of space breeding is still under debate. Scientists believe that space breeding mainly induces genetic variation in plant seeds through comprehensive environmental factors such as intense radiation, microgravity and high vacuum. Due to the shape of the earth’s plant over millions of years,
