护林员常常把注意力集中在有直接实际应用价值的树木的特性上，而忽略了它们的基本特性。直径增长就是一个很好的例子。通常每隔5年或10年在洞上的一个位置测量一次。这种方法忽略了生长的生物单位，即分布在茎的每一部分的一年生木质部层。本文描述了该生长层的一些特性。
Foresters have often concentrated their attention on characteristics of trees which had an immediate practical application and have neglected fundamental features. Diameter growth is a good example. Usually it has been measured at one position on the bole at 5- or 10-year intervals. Such a procedure ignores the biological unit of growth which is the annual layer of xylem laid down on every part of the stem. Some characteristics of that growth layer are described in this paper.
