Seed quality and seedling growth of Pinus elliottii Engelm which collected from Guangxi, Guangdong and Hunan three provinces were investigated and analyzed. Seedling cultivation was implemented using field seedlings and containers of two ways. The results showed that there were no significant difference with 1000-grain weight and seedling germination rate in different provenances. The degree of variation of 1000-grain weight in Guangdong provenance was the lowest and seedling germination rate was highest. There were no significant difference with height and ground diameter of 1 year field seedlings and 1 year container seedlings in different provenances respectively. In comparison, the provenance of the seedling growth of Guangxi was best. The height and ground diameter of 1 year field seedlings were significantly higher than that of container seedlings. This result indicated that different way of seedling had a great influence on seedling growth.
