EFFECT OF γ-RADIATION ON IMMATURE EAR CULTURE IN MAIZE |
| |
| Abstract: | The materials derived from immature ear culture of two self-bredlines were treated with ~(60)Co-radiation. Even though the frequency ofembryonic cells forming did not decrease, the frequency of distortionincreased and ability of differentiation was weaker. We think the em-bryonic cells treated with ~(60)Co-radiation of 500 ren produce not onlyhigh frequency of distortion, maintain but also the ability of differen-tiation. Meanwhile, the radiosensitivity of two poles of embryo differed. |
