Abstract
Anatomical and morphological features of the woody tissues of CoCoS nucifera L . is briefly reviewed in Part I. In Part II experimental data on basic physical properties through three radially displaced axes in the stem are provided and discussed. Variations through the three axes in basic density and air-dry density, vascular bundles (steles) , and moisture content at the time of testing were examined; included also was a brief look at volumetric shrinkage. Basic density appeared to decrease linearly with an increase in stem height and increased logarithmically from centre to cortex at any height of stem. Number of steles per square inch increased substantially with stem height accompanied by a marked decrease progressively from cortex to centre. -Moisture content approximated the theoretical maximum and increased considerably with stem height and from cortex to center. Shrinkage for the peripheral zone was almost the same throughout in the stem. Specimens from intermediate and core zones showed high incidence of collapse.
