ANATOMICAL VARIATION IN PLANTED KELEMPAYAN (NEOLAMARCKIA-CADAMBA, RUBIACEAE)

Six plantation grown Kelempayan trees [Neolamarckia cadamba (Roxb.) Bo sser, syn. Anthocephalus chinensis (Lamk.) A. Rich. ex Walp., Rubiacea e] were sampled along their radii and at five different height levels to evaluate variations of wood anatomical properties. Analysis of vari ance indicates that between tree differences in all anatomical propert ies measured were significant. Vessel proportion increases while ray p roportion decreases with height, while both fibre diameter and fibre l umen diameter decrease with height. No significant trend was found for fibre length vertically. Cell wall substance and vessel and ray propo rtion increase from pith to bark, while fibre proportion decreases. Fi bre length and fibre wall thickness increase from pith to bark, while fibre diameter and fibre lumen diameter first increase and then decrea se. Within-tree variations are more consistent radially than verticall y.
