Arg.1.Distribution pattern of tension wood and dimensional variation of wood fibres PY - 1989/// PB - Indian Journal of Natural Rubber Research KW - Gelatinous fibre KW - Hevea brasiliensis KW - Rubber wood KW - Tension wood KW - Wood fibre N2 - The distribution and proportion of tension and normal wood, the dimensional variations of wood fibres with emphasis on positional effect and their variation from tree to tree were studied in clone PB 86 of Hevea brasiliensis. The formation of tension wood increased with the increase in sampling height. The tension wood fibres (gelatinous fibres) were short and broad as compared to the normal wood fibres. The average fibre length showed significant difference among various height levels of the tree trunk ER -
