钴60辐射处理对大白菜植株的生长发育有明显的刺激作用。并且在适当的剂量范围内,有促进叶球生长,提高叶球产量的显著效果。该实验共分0.5、1、2、4、6、7、8、9、10、11、12、14、16和20万伦琴14个处理,辐射后,从室内和田间发芽率情况看,所有处理,出苗正常,与对照相差甚微。但随着苗龄的增加,明显表现出有刺激或抑制生长的作用。在0.5—2万伦琴低
Cobalt 60 radiation treatment has a significant stimulating effect on the growth and development of Chinese cabbage plants. And in the appropriate dose range, there is a significant effect of promoting the growth of leaf spheres and improving leaf yield. The experiment is divided into 0.5, 1, 2, 4, 6, 7, 8, 9, 10, 11, 12, 14, 16 and 20 million Roentgen 14 treatment, after radiation, from the indoor and field germination rate, Treatment, normal emergence, with little difference with the control. However, with the increase of seedling age, it obviously showed the effect of stimulating or inhibiting the growth. Low in 0.5-2 million Roren
