摘  要:
利用不同能量、剂量的H离子分别辐照耧斗菜干种子,以期研究离子注入能量、剂量与经处理后耧斗菜种子萌发率的关系,为确定耧斗菜离子注入诱变育种适宜的辐照剂量提供理论参考依据。结果表明:H离子辐照后种子的发芽曲线随着离子能量、剂量的增加呈不规则曲线变化,并对上述现象可能机理进行了讨论。

摘  要:
Dry seeds of Aquilegia hybrida were irradiated by H ion beams with different energy and dose,in order to study the effect of different energy and dose of ion-beam irradiation on the seed germination of Aquilegia and provide valuable information for the mutation breeding of Aquilegia.The results indicated that seed germination present irregular curve with the increasing of irridation doses of H ion beams with different energy.The possible mechanism were also disscussed.
