Wood density variations in Meranti timbers of Shorea species of Malay Peninsula.
The paper deals with the wood density variations in Meranti timbers. Meranti timbers are reclassified on the basis of wood density. In total, 36 species of Meranti timbers of Shorea were considered for the study. Out of 36 species, 9 species belongs to Meranti Pa'ang (White meranti), 7 species to Meranti dammar hitiam (Yellow meranti) and 20 species to Red meranti group of Shorea. Density variations among the species were significant while for replication of same species were non-significant. It showed that the species of Meranti groups varied as per the density. The Meranti timbers were classified using cluster analysis. On the basis of wood density the 36 timber species in question were classified as light to very light (density < 550 kg m-3), moderately heavy (density between 500-650 kg m-3), heavy (density between 650-700 kg m-3) and very heavy (density >700 kg m-3). Timbers of S. accuminata, S. lepidota, S. platycarpa, S. leprosula and S. ovalis belongs to light to very light class; S. maxima, S. lamellata, S. bracteolata, S. hemsleyana and S. multiflora to heavy class; S. dealbata, S. sericeiflora, S. pauciflora, S. roxburghii and S. macrantha to very heavy class and rest of the species were categorized under moderately heavy class. Therefore, Meranti group as a whole can not be treated for specific end uses as there is a great inter-species density variations.
