[Objective] To research the detection method for seeds vigor of Erigeron breviscapu. [Method] Effects of seed number and cultivation temperature on the germination rate were detected; TTC staining was used to detect the seed vigor. [Result] The germination rate of seeds was 15.37%, which was close to the germination rate on the 6th day. Germination rate varied greatly in germination tests of 100 and 700 seeds; but there are relatively few differences in the germination tests of 300 and 500 seeds. After TTC staining, E. breviscapu showed different characteristics. The overall colored seeds and bottom colored seeds could be regarded as vigorous seeds, the proportion of which was 15.00%. This value was close to the germination potential and germination rate. Thus, the experimental error was small. [Conclusion] This method was accurate and reliable and could be used for the preliminarily detection of seed vigor of E. breviscapu.
