In order to realize the cultivation of Asiasarum sieboldii from the seed, the growth condition of the embryos and germination conditions of the seeds were studied. Although the embryos of the seeds soon after harvest were immature and undifferentiated, they grew to differentiate into cotyledons and radicles during storage in wet sand at room temperature, and germinated with rooting 120 days after harvest. The optimum temperatures for growth of the embryos and the germination of the seeds were shown to be 15-20℃, whereas more than 90% success rate was obtained in about 60 days on the germination test in petri dishes. On the other hand, the optimum temperature for seedling emergence is thought to be 8-10℃, since the germinated seeds planted in a sowing bed sprouted in the early spring after lower temperature in winter.
