Abstract: In this research, the moisture content and biomass distribution of 1.5-year old Phoebe bournei container seedling at different height stages were measured and analyzed. The results showed that: (1)With the increase of seedling height, the biomass and its components in P.bournei container seedling increased. The biomass allocated in the order of root biomass>leaf biomass>stem biomass>branch biomass. With the increase of seedling height, the biomass of stem increased, while the biomass of leaf first increased and then decreased, and the biomass of root first decreased and then increased. The biomass as well as its components are significant correlated to basal diameter (D) and height (H) except branch. (2)The moisture contents of stem and leaf reach peak values while the seedling height was between 20 and 25 cm, the moisture content of root reach peak value while it between 35 and 45 cm. (3)Root moisture content as well as leaf, stem and aboveground biomass are significant positive correlated, while a significant negative correlation between leaf moisture content and different organs biomass was identified.
