摘　　要：木本植物芽的内休眠是植物经过长期演化而获得的一种对环境及季节性变化的生物学适应性,其机制较为复杂。了解内休眠的机制,调控芽的休眠与萌发,具有重要的理论意义和应用价值。在探讨内休眠概念的基础上,重点阐述内休眠诱导及解除的影响因素、内休眠过程中的代谢变化、顶端分生组织内细胞间通讯及细胞周期调控、内休眠相关基因等方面的研究进展,提出今后内休眠调控机制的研究重点。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.
