Study on Seedling Stage Growth Characteristics of Cinnamomum camphora

The differences of seedling stage growth characteristics of Cinnamomum camphora were analyzed in this paper,they provide references for choosing high quality provenance of C.camphora.The research showed that annual seedling of C.camphora with different provenance haven't obvious difference in height,at the same time they have apparent distinction in diameter.Height and diameter haven't obvious geographic trends change,and also have no correlation between latitude and longitude,but after been divided appropriately,the seedling height demonstrated the change law that lower latitude while greater seedling height with the longitude and latitude.Diameter growth characteristics were rather complicated and affected by many factors.Based on the characteristics of seedling height and diameter,the provenance of C.camphora were divided into six zone.
