One-year-old seedlings of Cinnamomum camphora were planted with four densities: 1, 2, 4, and 8 seedlings per bag (density I, II, III and IV). The effect of the planting density on the growth and weight distribution pattern of these seedlings were studied. The?results showed that the mean ground diameter decreased with an increase of the density. The mean seedling height was in the order of III> IV> II> I density for C. camphora seedlings. The dry weight of roots, stems, branches, and leaves and the total tree dry weight of C. camphora seedlings decreased with increasing density. The dry weight of individual organs decreased in the order of roots > leaves > stems > branches in density I and roots > stems > leaves > branches in other density plantings. The root-shoot ratio of seedlings in all density treatments was >1.
