摘　　要：以6个剂量的^(60)Co-γ射线辐照4个桑树(Morus L.)品种的干燥种子,分析了辐照后各品种的发芽情况。结果表明,辐照主要影响桑树种子的发芽势和生根能力,分析各品种对辐射的耐受性,以冀桑3号的耐受能力最强。通过辐照后种子发芽及生根情况的比较,得出桑树种子辐照致死剂量为2 500 Gy。Four dried seeds of mulberry（Morus L.） were irradiated by^（60）Co-γ rays at 6 dose, the germination of the varieties were analyzed after irradiation. The results showed that irradiation mainly affects the germination potential and rooting ability of sage mulberry seeds. Analysis on the tolerance showed that Jisang No.3 was the strongest. Through the investigation of the germination and rooting of the seeds after irradiation, the lethal dose of mulberry seeds was 2 500 Gy.
