离子束辐照对孔雀草发芽特性的影响

摘要

In order to prove influence law of ion irradiation process parameters on germination characteristics of maidenhair ,the maidenhair seeds were irradiated by the low-energy nitrogen ion beam ,and the effects of nitro-gen ion irradiation process parameters on the germination characteristics of maidenhair seed were studied ,inclu-ding germination rate and germination time .The results showed that with the increasing of ion irradiation ener-gy and dose ,the germination rate of maidenhair seed decreased and the germination time would be delayed .%为探明离子辐照工艺参数对孔雀草发芽特性的影响规律，采用低能氮离子束对孔雀草种子进行辐照，研究了氮离子辐照工艺参数对辐照后的孔雀草种子发芽率和发芽时间等发芽特性的影响。结果表明，随着离子辐照能量和剂量的增加，孔雀草种子的发芽率降低，发芽时间推迟。
