| 摘 要： | 以60Coγ射线对‘展翅’荷兰鸢尾种球进行辐照,对各处理的出苗率、成活率、株高、植株形态变化、子球繁育等指标做调查统计。结果表明,在3~10Gy范围内,随着剂量的加大,植株的辐照损伤效应也逐渐加强;且大种球耐辐照能力大于小种球;辐照对M2代植株开花仍有很大的影响,其中7Gy处理的M2代植株变异率相对最高,成活率也较高,并能得到优变单株。根据结果确定‘展翅’荷兰鸢尾小种球适宜的辐照剂量为7~8Gy。

| Abstract: | The bulbs of Iris hollandica ‘Zhan chi’ were irradiated with 60Coγ -rays in this study, using group indexes of damages to the growth and development for statistical investigation, such as emergence rate of seedlings, survival rate and plant height, morphological changes and so on. The results showed that the damaging effects of irradiation on plant were gradually strengthened as the doses increased within the range from 3 Gy to 10 Gy. Moreover, the sensitivity to irradiation of the small bulblets was stronger than those of big ones. Besides, the irradiation still had great effects on the blossom of regenerated plants from M2 generation, and those under 7 Gy presented highest variation rate and survival rate, with excellent single mutant obtained. According to these results, the suitable irradiation dose to the young bulbs of Iris hollandica ‘Zhan chi’ could be determined within the range from 7 Gy to 8 Gy. |
