| 摘 要： | 目的]阐述离子束诱变植物的数量性状。方法]调查了离子束诱变小麦同一母本后代的特殊变异表型、农艺性状、蛋白质和湿面筋含量。结果]有的个体表现出形态学多样性。株高、穗长和蛋白质含量受离子束显著影响,有效分蘖数和湿面筋含量受到轻微影响。多重比较表明各组性状存在不稳定性。结论]离子束辐射呈现多样性和不定向性的特点,可以对同一突变体造成多种变异。后代性状的不稳定性暗示同一辐射区域的细胞也可能有不同命运。特定性状可能要经过数代才会稳定。离子束辐射效应可能是直接辐射损伤、间接辐射损伤和旁观者效应和自适应效应的综合效应。

| Abstract: | Objective] The aim of this study was to elucidate the quantitative traits of plants mutagenized by ion beam.Method] The particular variation phenotypes,agronomic traits,and protein and wet gluten contents of progenies derived from the same ion beam induced mutant were investigated.Result] Morphological polymorphism existed in some individuals.Plant height,spike length and protein content were significantly influenced by ion beam,and effective tiller number and wet gluten content were moderately influenced.Multiple comparisons of all the indices within groups indicated genomic instability among these groups.Coefficient of variation implied the differences within group were very low.Conclusion] Ion beam irradiation displayed characteristics of multi-directivity and non-directiveness.It aroused multiple variations in the same mutant.Instability among progeny indicates cells had different fate even in the same irradiated tissue.It may take several generations for mutants to stabilize particular phenotypes.The effects of ion beam irradiation may be the interrelated direct irradiation damage,indirect irradiation damage and late effect,such as bystander effect and adaptive response. |
