Background : This study was carried out to provide the basic data for selection of excellent resources and true seeds of southern medicinal plant (Camellia japonica). Methods and Results : Camellia japonica seedlings (measure in October, seeding in May) were 7.4 leaves, 1.0 g leaf dry weight, 6.7 ㎝ stem length, 2.9 ㎜ stem diameter, 0.3 g stem dry weight, 17.3 ㎝ root length, 1.0 g root dry weight, 2.0 g plant dry weight and 1.4. T/R ratio. Leaf number, leaf dry weight, stem diameter and root dry weight were higher than average after 1.21 g of seed weight. Stem length was higher than average after 1.01 g of seed weight, plant dry weight was higher than average after 0.81 g of seed weight, and stem dry weight was higher than average after 0.61 g of seed weight. Seedling growth was good when the seeds were heavy, and T/R ratio tended to decrease when the seeds were heavy. Conclusions : In order to mass-produce of seedlings using Camellia japonica seeds, it was necessary to specify the weight and size of the seeds.
