四年来的观察說明,用Co~(60)γ射线照射花生干种子和催芽种子均能誘发变异,其有效的誘变剂量对于干种子在40000伦以上,对于催芽种子在8000伦以上。但照射当代所产生的輻射形变一般都不能真实遺传,在第二代(x2)和第三代(x3)一般都有分离現象出現,而变异的出現和新遺传性的形成与植株所处的生态环境有密切的关系。 Over the past four years, it has been demonstrated that irradiation of Co ~ (60) γ-rays on both ground and germinated seeds of peanut can induce variation with an effective mutagenicity of more than 40,000 for dry seeds and more than 8,000 for germinated seeds. However, radiation exposure caused by radiation in the contemporary era can not be generally inherited. In the second generation (x2) and the third generation (x3), there are generally isolated phenomena, and the emergence of mutations and new hereditary formation and plant Department of the ecological environment are closely related.
