Resumo

This paper deals with the macroscopic and microscopic observation of the growth ringe in two disks from the crossing section of wood stem of Tecoma chrysothrica and also deals with statistical analysis of the size of fiber and vessel member in different grow rings of secondary xilem. By statistical analyses of variance the authors verified the following: first, the fiber reaches its utmost length at the 11 th and 12 th grow rings; second, the vessel member reaches its utmost width in the same region as the fiber length. This point out there is certain correlation between the width of vesses member with the fiber length at the same growth rings. There was no statistical signification in the variation of the vessel length and the fiber width.
