| This study was conducted to clarify the characteristics of seed germination and to promote the germination rate in Pollia japonica Thunb. that was pointed to protect by the Office of Forestry in 1997. It was better the germination rate and the growth of in the light than those of in the darkness. The seed germination of Pollia japonica showed the highest germination rate at $20^{circ}C$ any other treated temperature. To increase the germination rate of Pollia japonica, it was conducted priming treatments and storage treatments at $4^{circ}C$. Priming treatments using 1% NaOH, 1% KOH for 30min were effective compared to control, but soaking of 100mg/L GA3 for 24 hours, 1% NaOCl for 30min were not useful. It was higher in wet storage than in dry storage. Wet storage of seeds showed a germination rate with 95.3% in 90-day treatment, which improved 55.3% than dry storage in 90-day. |
