Arg.1.Distribution pattern of tension wood and dimensional variation of wood fibres  bIndian Journal of Natural Rubber Researchc1989  a27-37  aThe 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.  aGelatinous fibre  aHevea brasiliensis  aRubber wood  aTension wood  aWood fibre  aPanikkar A O N  aPremakumari D
