| 摘 要： | 用60Coγ射线辐射扶芳藤干种子和枝条,结果表明,种子辐照后其发芽率、出苗率和存苗率均受到抑制,与辐射剂量呈极显著负相关。辐照处理后第1真叶期明显晚于对照,并且植株生长随剂量增大变缓慢。种子的半致死剂量为128.56Gy。枝条辐射后插穗生根的数量和长度与剂量呈极显著负相关,枝条的半致死剂量为95.54Gy。 |

| Abstract: | Seeds and plant branches of Euonymus fortunei were irradiated with()~(60)Co γ-ray.The results showed that after irradiation,seed germination rate, emergence rate and surviving rate were restrained,and it was negatively correlated with irradiation dose increasing significantly.The first euphylis period was delayed compared with control.Seedling height decreased with the increase of irradiation dose.Semi-lethal dose of Euonymus fortunei seeds was 128.56Gy.Branch irradiation could cause significantly number and length reduced,and it is correlated with irradiation dose increasing.The semi-lethal dose for Euonymus fortunei branches was 95.54Gy. |
