| 摘 要： | 华山松催芽后的种子用60Coγ射线辐照,种植结果表明:辐照延缓了种子萌芽期和萌芽高峰期,降低了萌芽率和幼苗的生活力,同时也降低了黄色苗在幼苗中的比例和幼苗的生长高度,对黄色苗的抑制作用更为明显。

| Abstract: | The soaking seeds of Pinus armandi Franch. were irradiated with 60Co γ-ray at dose of 0, 20, 40, 60 and 80 Gy, and the treated seeds were planted. The result showed that the irradiation treatment retarded the time of germination, and the seed germination rate, for reduced, the ratio of yellow to living seedlings. The treatment also lowered the height of seeding, especially for the yellow seedlings. |
