In this study,Different treatment methods such as water absorption time、different storage time、low temperature stratification、temperature and light、and exogenous hormones were used to study the seed germination rate of Euptelea pleiospermum.The results showed that the highest water absorption rate was 15.3％after soaking for 24 h.The highest seed germination rate was 83.33％when the seeds were stored at room temperature for 90 days.The longer the low-temperature stratification time was,the lower the seed ger-mination rate was.Under constant temperature of 25 ℃ and 1 000 Lux light condition,the germination rate reached 86.67％,and the light condition was more suitable for seed germination.There was little difference in germination rate between the 500 mg/L NAA and 200 mg/L ABT treatments with three exogenous hormone treatments.The highest germination rate was 86.67％when the NAA concentration was 500 mg/L.IBA treat-ment had the worst effect on seed germination rate.
