Camellia japonica L.
is an evergreen tree, belonging to family Theaceae. The species naturally
distributes in China, Taiwan, Korea, and southern Japan. It has been widely
planted for ornamenting purpose. Also, C. japonica oil has been extracted and
used for healthcare. In this study, seed germination and initial seedling
growth of C. japonica were experimented in Hanoi, Vietnam.Seeds were collected
in January in Kyoto, Japan and transported to Vietnam. Seeds were stored in
normal room conditions until the experiment in February. Pre-sowing treatment
was conducted by soaking in 50-55oC ordinary water until reaching normal
temperature. Treated seeds were then sown in wet sandy bed for germination.
Germinated seeds were then transplanted to forested-soil pots and tended
normally by watering twice a day without fertilization and pest/disease
control. The results indicated that the first seed germinated was recorded 3
weeks after experimenting, and germination ended in 2 weeks from the first
germination. Most seeds germinated in the duration of 5th day to 10th day after
the first germination. The germination rate was 62.5% and seedling survival
rate was 96.8% at 4 months of growth. Seedlings of 4 months old had an average
height of 15.9 cm, diameter at the stump of 2.1 mm, the taproot of 11.4 cm
long, and average 10.6 leaves/seedling. It is possible to grow C. japonica in
Vietnam. However, further study should be conducted in the field conditions.
