^(60)Co-γ辐射对丛生福禄考植株形态的影响

Effects of ^(60)Co γ-rays Irradiation on Growthform of Phlox subulate

采用不同剂量(0～100 Gy) ^(60)Co-γ射线,辐射丛生福禄考带芽茎段的研究结果表明:30～60 Gy的辐射利于丛生福禄考的形态发生变异,宜适辐射诱变剂量为60 Gy;80～100 Gy高剂量的辐射抑制植株生长,且随着辐射剂量的加大,抑制作用增加。

The sedum spectabile were treated by 0~100 Gy ^60Coγ-rays, growthform was analyzed in this paper. The results showed that the radiation of 30~60 Gy was beneficial to the morphological variation of Phlox subulate, and the appropriate dosage was 60 Gy. Higher dose of 80~100 Gy inhibited plant growth, and the inhibitory effect increased with the increase of radiation dose.
