Abstract:

The bud endo dormancy in woody perennials, which formed during a long evolutional process, is a biological adaptability to the changes of environmental factors and different seasons. It is important in both theory and application to understand the complex mechanisms of how to induce or break bud dormancy. In this paper, the emphases were put on the factors that induced and broke bud endo dormancy, the changes in metabolism during endodormancy, the cellto cell communication and cellcycle signaling in apical meristem, and the genes associated with endodormancy. Finally, we proposed some aspects of studies on bud endodormancy mechanism in the future.

Key words: bud, endodormancy, induce, release, mechanism
