| 内容記述 | Garden stock (Matthiola incana (L.) R.Br.) is a major floricultural plant in the winter season. In this study, dry seeds of Matthiola incana were irradiated with carbon (C) and iron (Fe) ion beams to investigate the effective element species and absorbed doses. The survival rate of the M1 generation tended to decrease with increasing absorbed dose, and the absorbed dose-survival rate curve showed a shoulder at absorbed doses of 100 Gy in C-irradiation and 10 Gy in Fe-irradiation. Some shoot and flower morphogenetic mutants were obtained in the M2 progenies. The shoot mutants contained dwarf, multibranch, and enlarged floral axis individuals, while the flower mutants had darker petal colors, narrowed petals, and an increased number of petals. The mutation rate increased with elevating absorbed dose and showed a negative correlation with the survival rate. Based on these results, it was suggested that absorbed doses of 100 Gy in C and 10 Gy in Fe, which are the shoulders of the absorbed dose-survival rate curve, are effective indicators for generating Matthiola incana mutants. The mutated flower phenotype was stably inherited, but the shoot mutant inheritance varied. These results demonstrate that ion beam irradiation of Matthiola incana dry seeds can produce mutants. |
