The purpose of this study was to investigate the characteristics of seed production, germination and seedling growth for the restoration of the vulnerable plant species Penthorum chinense. A large number of minute seeds were produced and great percentage of germination was observed at the wide range of temperature. Light and alternating temperature were required for germination. Seeds covered with soil could not germinated. Seedling growth was poor in the infertile soil and in the excessive fertile soil. The safe site of seedling was considered to contain proper amount of nutrient in the soil and less seeds of strong competition. It was expected to restore Penthorwn chinense community by direct sowing or planting with pot cultured seedlings.
