In order to explore the feasibility of cryopreservation on dormant forest tree seeds,the seed viability of 4 species(Malus baccata,Prunus davidiana,P.armenica and Amygdalu persica) with moisture content(MC) changing was tested after 30-day storage in liquid nitrogen of -196℃.The results showed that all the 4 species of seeds can keep a stable viability after cryopreservation.In the procedure,the optimum MC was 48 g/kg for M.baccata,27 g/kg for P.davidiana,31 g/kg for P.armenica and 45 g/kg for A.persica, respectively.It was feasible to store all the 4 species of seeds in liquid nitrogen.
