The effects of cryomethods, cryoprotectants, pollen age and pollen water content on the viability of pollen in Fritillaria thunbergii after cryopreservation were studied. The viability came highest (56.4%) when pollen of the flowering day (20% pollen water content) was treated by step-cooling. Hybridization in the fields showed that cryopreserved pollen could go to seed as well.
