In woody plant germplasms, using prefrozen dormant buds for materials is one way to achieve successful cryopreservation. The protocol of cryopreservation for White birch (Betula platyphylla var. japonica) winter vegetative buds is the following. First, the branches of White birch were collected in January 20, when the vegetative buds were still in a state of quiescence. The winter buds with about 5§® of xylem tissue were removed from the branches. They were dehydrated to moisture contents about 44% by air dry treatment. The buds were prefrozen, with the temperature being decreased by 5¡­-20$^{C}$ and then transfered to the LN(liquid nitrogen) maintained below -l96$^{C}$. After cryopreservation, the vegetative buds were rapidly thawed in a water bath at 40$pm$5$^{C}$. In this case, the cell survival rate of samples was about 86%. After sterilization, buds were then cultured on MS medium. These results demonstrate the feasibility for cryopreservation of winter vegetation buds of Betula platyphylla var. japonica.
