Because Lysimachia mauritiana is not able to maintain the seed viablity for a long time, it has difficulties in using for the ornamental plants or landscape gardening. This study was conducted to elucidate the optimal germination conditions of Lysimachia mauritiana seeds. The germination rate of the seeds was higer in light condition than in dark one. In experment determining the proper germination temperature, the germination rates were 2.2%, 96.9% and 91.2% under 35$circ $C, 25$circ $C, and 20$circ $C, respectively in light condition. The approprate temperature for the germination was 25$circ $C in light. The decreases of germination rate with the increase of the preservation periods was able to recover by priming pretreated with NaCl solution and KNO$_{3}$ + K$_{3}$H$_{2}$PO mixed solutions. When the storage period was 300 days, the germination rate was 75% without priming treatments. But the seeds primed with NaCl 0.1M and KNO$_{3}$ + K$_{3}$H$_{2}$PO mixed solutions 0.1M, showed germination rate above 90%. T$_{50}$ also was shorten from 5.25 without priming to 3.78 with NaCl 0.1M. Seed priming may induce earlier sprouts and increase germination rate of long-preserved seeds of native wild plants.
