在树木年轮中观察和测量的木材解剖和结构特征已被证明在树木年代学中是有用的。他们增加了对树中正在进行的过程的理解和新的见解，这些树的结构特征显示了与环境参数的联系，而不是由其他参数给出的。这篇综述主要强调在陈年年轮中测量的连续和非连续木材解剖特征方面所做的工作，反映了内部和外部条件和过程。这篇综述还包括在德国东奥雷山脉进行的一项研究的新结果，该研究测量了在严重压力下生长的树木年轮的几个解剖特征。它展示了环境变化如何导致陈年年轮结构特征的修改或适应。树木年轮的许多结构特征的测量仍然很繁琐，尽管对于一些特征，如细胞大小或微纤丝角，现在已经有了快速扫描设备。总体而言，木材解剖表明，树木的生长发育是动态的过程。所有这些通常以二维和三维来说明的方面，实际上都有第四个维度--时间。
Summary Wood anatomical and structural features observed and measured in tree- rings have proved to be useful in dendrochronology. They have added understanding and new insights to processes going on in trees with structural features that have shown linkages to environmental parameters, not given by other parameters. This review emphasizes work done primarily on continuous and non-continuous wood anatomical features measured in dated tree-rings, reflecting internal and external conditions and processes. This review also includes new results from a study conducted in the East-Ore Mountains, Germany, where several anatomical features in rings of trees grown under severe stresses were measured. It is shown how environmental changes have caused modifications or adaptations of structural features in dated tree-rings. The measurement of many structural features in tree-rings remains tedious, although for some features such as cell sizes or microfibril angle fast scanning devices have now been made available. Overall, wood anatomy indicates that growth and development of trees are dynamic processes. All these aspects, which are commonly illustrated in two and three dimensions, have in reality a fourth dimension – time.
