[Temperature requirements for afterripening of the embryo of Fritillaria cirrhosa Don.f].
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 degrees C is the most suitable temperature for the earlier stage of morphological development of the embryos, and 10 degrees C for the later stage. To release from the physiological dormancy, chilling at 5 degrees C for 73-91 days is desirable.
