บทคัดย่อ (EN): Lignins are the second largest phenolic bio-polymers of the cell wall after cellulose and their deposition is associated with mechanical strength, improved sap conduction, defense mechanisms and imperviousness to biodegradation. As the biosynthesis of lignin and polyphenolic derivatives in living trees, especially in fast growing woody species like Hevea, facilitates the improvement of quality and durability of timber to a great extent, these two wood quality traits has been considered for the early selection of timber quality in Hevea brasiliensis. A study was conducted in stems of 19 wild Hevea germplasm accessions and six popular Wickham clones in the juvenile growth phase to estimate and quantify the insoluble lignin content and wall associated phenolics. The results revealed that the quantity of lignin produced was increased in association with the progress of secondary thickening. Variation in the percentage of lignin and cell wall phenolics between the wild accessions and Wickham clones was highly significant. In wild Hevea germplasm the lignin percentage ranged from 19.28 – 24.75 % whereas 20.84 – 23.36 % in Wickham clones. Of the 19 wild accessions analysed, three showed significantly higher percentage of lignin over five Wickham clones. With regard to cell wall phenolics, twelve wild accessions had significantly higher percentage than that of Wickham clones. The study revealed that the quantification of lignin bio-polymer and cell wall phenolics can be used as reliable tools for the early detection of wood quality in Hevea brasiliensis.
