In order to explore the feasibility of cryopreservation storage on forest tree seeds, germination of Amorpha fruticosa and Platycladus orientalis seeds with moisture content (MC) changing was tested after storage in liquid nitrogen of -196 oC for 30 d. The results showed that both species of seeds can keep high germination percentage after cryopreservation. For A. fruticosa, the germination percentage of seeds was the highest when 4.1% MC was used for storage, and for P. orientalis it was the highest when 6.0% MC was used for storage. It is feasible for both species of seeds to be stored in liquid nitrogen.
