已知电高射线如X射线等对生物有强烈的诱变作用。X射线和γ射线对海带雌配子体的效应已有初步观察。过去用于海带实验的是雌雄配子体混合在一起的材料,如果发生突变,不易观察到,这是因为受精后是二倍体。这里我们对能行孤雌生殖 It is known that electrical high rays such as X-rays have a strong mutagenic effect on living organisms. Effects of X-rays and γ-rays on female gametophyte of kelp have been initially observed. In the past for the kelp experiment is mixed with male and female gametophyte materials, if the mutation is not easy to observe, this is because the diploid after fertilization. Here we can practice parthenogenesis
