首次采用放射性~7Be离子注入玉米种子。结果表明,33MeV和14MeV能量的~7Be离子均能不同份额地穿透种皮,注入到胚体,并诱发根尖染色体畸变,引起PAL活性和丙二醛含量的变化;M_1代幼苗的形态也出现畸形。
The first use of radioactive ~ 7Be ions into corn seeds. The results showed that both 33 MeV and 14 MeV energies of ~ 7Be ions penetrated the seed coat in different portions, injected into the embryoid body and induced root tip chromosome aberration, resulting in the changes of PAL activity and malondialdehyde content. The morphology of M_1 seedlings Deformity.
