摘要
为给今后的研究和生产提供参考,利用LZD-1000型离子注入机对伞树种子进行处理,测定其发芽势和发芽率。结果表明:经N和Ti离子处理后,伞树种子的发芽势和发芽率均降低,其变化呈"降—升—降"的"马鞍型"曲线,且这2个指标与离子注入剂量之间均呈现极显著相关,200×1014 ion/cm2的低剂量离子注入对种子发芽较有利,N离子源效果更好。
In order to provide reference for research and production in future, some seeds in Acacia saligna were treated by using LZD-1000 type ion implanter, and germination force and germination percentage of seeds were determined. The results indicated that both germination force and germination percentage are decreased after treated by N and Ti ion injections, their changes present the saddle type curves of down-up-down, and the two indexes have very signiifcant relationship with ion implantation dose. The low dose of ion injection （200×1014 ion/cm2） is favorable for seed germination, and N ion injection has better effect than Ti ion injection.
