The mutation effect of C6+heavy ion on the dry seed of Lathyrus sativus L.has been studied in this report.It has been found that this heavy ion had a obvious suppression effect on the percentages of germination and seedling formation,and the growth rate of young roots and seedlings.The degree of the suppression showed a clear positive relation with the radiation dose.C6+heavy ion induced the mitotic aberration of not only a higher frequency but also a wider spectrum at the low and medium doses,compared...

The mutation effect of C6+heavy ion on the dry seed of Lathyrus sativus L.has been studied in this report.It has been found that this heavy ion had a obvious suppression effect on the percentages of germination and seedling formation,and the growth rate of young roots and seedlings.The degree of the suppression showed a clear positive relation with the radiation dose.C6+heavy ion induced the mitotic aberration of not only a higher frequency but also a wider spectrum at the low and medium doses,compared with that by 60Co-ray.It is suggested that it is possible for C6+heavy ion radiation to induce usable mutation instead of producing more serious lesions.The problem about the dose of C6+heavy ion suitable for inducing the low-or non-toxin Lathyrus sativus L.is discussed.

本实验探讨了C~(6+)重离子对山黧豆种子的诱变效应,结果发现,C~(6+)重离子对山黧豆种子的萌发率、成苗率、幼根及幼苗生长速度有着显著的影响,而且辐照剂量与效应呈明显正相关,此外,与~(60)Co-γ射线相比,C~(6+)重离子不仅诱导形成了较高的有丝分裂畸变率,而且还能在所用剂量的低中级剂量范围内(10~2—10~5P/cm~2)产生较宽广的畸变谱,表明C~(6+)重离子照射有可能在辐射损伤较小的情况下产生有用突变。文章还推论了C~(6+)重离子在山黧豆无毒或低毒品系的诱变育种中可能采用的剂量范围。

The effects of N+ ion beam implantation on seed germinating rate and root-tip mitotic aberration rate for dry and sprouting seeds are compared. Results show that N+ ion beam implantation brought about obvious effects on sprouting seeds but little effects on dry seeds. Within the range of dose (0- 6x 1016/cm2), the mitotic aberrations of sprouting seeds induced by N+ ion beam implantation are higher than those of dry seeds, and they all increase with the increasing implantation dose; but when the...

The effects of N+ ion beam implantation on seed germinating rate and root-tip mitotic aberration rate for dry and sprouting seeds are compared. Results show that N+ ion beam implantation brought about obvious effects on sprouting seeds but little effects on dry seeds. Within the range of dose (0- 6x 1016/cm2), the mitotic aberrations of sprouting seeds induced by N+ ion beam implantation are higher than those of dry seeds, and they all increase with the increasing implantation dose; but when the implantation dose is higher than 6 x 1016/cm2, they all show some degree of saturation. Possible mechanism of aberration effects induced by N+ ion beam implantation is briefly discussed.

比较研究了低能重离子束注入小麦干种子和萌动的种子对种子发芽及根尖细胞有丝分裂畸变的影响。结果表明,离子注入对萌动的种子的发芽有明显的影响,而对干种子的发芽影响不明显。在一定剂量范围内(0-6×10~(16)/cm~2), N+注入诱导的萌动种子的有丝分裂畸变率略高于干种子,并且随辐射剂量的升高而升高;但超过一定的剂量(>6×10~(16)/cm~2),无论是干种子还是萌动种子的有丝分裂畸变率达到一定程度的饱和。就实验结果对N~+离子束注入诱变的机理进行了一些探讨。
