The results showed that 20 Gy radiation dose can promote the germination rate compared with the control group, and the germination time was shortened. Under the radiation dose of 200Gy, the seeds could not germinate. The semi-lethal dose (LD50) was 78.08 Gy. The biological statistics analysis indicated the radiation dose had larger impact on plant height and leaf length, and had little effect on blade quantity and less influence on the leaf width. These results will lay the theory basis for radiation breeding of Epidendium secundum. %U https://www.hnxb.org.cn/EN/10.11869/j.issn.100-8551.2017.09.1693
