在能量50 keV的条件下，将不同剂量的Fe ＋及Ti ＋注入杉木种子，观察离子束注入后对种子萌发及幼苗形态学的影响。结果表明：Fe ＋及Ti ＋注入对种子发芽有延迟效应，且发芽率随离子束注入剂量的增高呈下降趋势；离子束注入剂量对杉木主根初期的生长具有显著抑制作用，不同剂量Fe ＋的注入可使根长大幅度下降，即根长对Fe ＋的敏感程度更高；处理组与对照相比苗高均值相差不大，但个体上经Fe ＋处理的突变率高于Ti ＋处理，经离子注入处理组共有7株优势苗入选。

The effect of different dosage injection of Fe +and Ti +into Cunninghamia lanceolata seeds under 50 keV energy condition on seed germination and morphological characteristics and growth indexes of the seedlings were observed in the study.The results show that Fe +and Ti +injection had a delay effect on seed germination,the germination rate dropped along with the dosage increase of Fe +and Ti +ions injected into the seeds.The early stage of seedling root growth was significantly inhibited by ion beam injection.The root length of the seedlings was sharply reduced along with the increment of Fe +dosage injected,indicating that the root length of C.lanceolata seedlings was highly sensitive to Fe +ion.There were no significant differences in seedling height among the treat-ments and the control group,but the mutation rate of seedligns injected with Fe +ion was higher than that of injec-ted with Ti +ion.7 superior seedlings were selected from treatment group with ion beam injection.
