Abstract: Seedling stage is an important period for forestry. The aim of this study was to estimate the growth trend of six local precious species and consider their implications for silviculture on forestry. We assessed height, diameter near ground and crown width at 1, 4, 6 and 8-month. The variance analysis indicated that there were significant differences between species on all traits except diameter near ground and crown width at 8-month. There were no significant differences on height and crown width at all ages among replicates whereas there were significant differences on diameter near ground at 1 and 4 months, differences on diameter near ground at 6 months and no difference on diameter near ground at 8-month. The significant differences among interaction of species and replicates on diameter near ground at 1-months, 4-month, 6-month and crown width at 8-month were also found. Dalbergia odorifera had a higher growth period after 6-month. Aquilaria sinensis (Lour.) Spreng, Swietenia mahagoni (L.) Jacq., Hopea hainanensis Merr. et Chun, Homalium hainanense Gagnep. and Cassia siamea Lam. had the same growth trend on all traits at the whole time.
