摘　　要：采用^(60)Co-γ射线对岑软2号、岑软3号、岑软11号3个普通油茶(Camellia oleifera)无性系种子和连州1号普通油茶优树种子进行0、1 000、2 000、3 000 rad剂量辐照处理,研究辐照对油茶实生苗鲜果出籽率、晒干出籽率、干籽出仁率、种仁含油率、鲜果含油率等经济指标的影响。结果表明:不同剂量辐照处理对岑软2号、11号的实生苗出籽率有显著影响(P<0.01),对岑软3号的出籽率影响不显著,不同无性系间辐照影响差异较大;3 000 rad辐射明显提高岑软2号、3号和连州1号的种仁含油率和鲜果含油率,抑制了岑软11号的种仁含油率和鲜果含油率。The ^60Co-γ radiation treatment was utilized for the seeds of 3 Camellia oleifera Abel clones （ Camellia oleifera ‘Cenruan NO. 2’,Camellia oleifera‘Cenruan NO. 3’ and Camellia oleifera ‘Cenruan NO. 11’） and the seeds of Camellia oleifera Abel plus tree （ Camellia oleifera ‘ Lianzhou NO. 1’） via 0 rad, 1000 rad, 2000 rad, 3000 rad, in order to study the effect of ^60Co-γ rays irradiation treatments on fresh seed rate, dried seed rate, kernel rate, seed oil content rate and fresh fruit oil content rate. The result showed that 4 camellia trees under different 60Co-γ radiation treatments effected the seed rate of Camellia oleifera ‘Cenruan NO. 2’ and Camellia oleifera ‘Cenruan NO. 11’ significantly while Camellia oleifera‘Cenruan NO. 3’with no significant impact; High dose ^60Co-γ rays irradiation increased the oil content rate of Camellia oleifera ‘Cenruan NO. 2’,Camellia oleifera‘Cenruan NO. 3’ and Camellia oleifera ‘ Lianzhou NO. 1’,while high dose 60Co-γ rays irradiation decreased the Camellia oleifera ‘Cenruan NO. 11’oil content rate.
