不同剂量的N~+离子注入小麦风干种子,对发芽率、成苗率、成活株率的影响,品种间有较大差异。离子注入对M_1代幼苗高度和根长均有抑制效应,但品种间反应各异;离子处理也抑制单株根数,影响单株多根的比例;离子注入染色体损伤较轻,可产生一定数量的微核细胞率,但较γ射线处理低得多;离子注入小麦的过氧化物酶同工酶酶谱无变化,但酶的活性增强。 Different doses of N ~ + ions infused wheat dried seeds, the germination rate, the rate of seedlings, the survival rate of plants, there is a big difference between varieties. Ion implantation inhibited the height and root length of seedlings in M_1 generation, but had different responses among cultivars. Ion treatment also inhibited the number of single plants and affected the ratio of multiple plants. Ion implantation had a lesser degree of chromosome damage and could produce a certain amount of The micronucleus rate of wheat was much lower than that of γ-ray treatment. The peroxidase isozymes of ion-implanted wheat showed no change but enzyme activity increased.
