LI Pei-Wang, LI Chang-Zhu, JIANG Li-Juan, SUN You-Ping (Hunan Academy of Forestry, Changsha 410004, Hunan, China; Central South University of Forestry & Technology, Changsha 410004, Hunan, China)  
The seeds of Cornus wilsoniama, Euphorbia lathyris and Jatropha curcas, were taken as materials, germination rate, germination vigor, germination index and vigor index of the seeds were investigated by the randomized block experiment, the data were analyzed by SPSS, and the internal and external factors affecting the vigor index were discussed. The results showed that the germination vigor could well reflect the germination speed, uniformity of a lot and potential of seedling growth. The main factor affecting germination vigor was specie, that was,the genetic and physiological differences. The external factors affecting germination vigor were water, temperature, illumination, and so on. So seeds germination was contributed to the combined action of internal and external factors.
