Abstract:The seeds of Fritillaria cirrhosa contain immature embryos at harvest. To afterripen the embryos, different temperatures are required at different stages. Experiments show that 15℃ is the most suitable temperature for the earlier stage of morphological development of the embryos, and 10℃ for the later stage. To release from the physiological dormancy, chilling at 5℃ for 73～91 days is desirable.
