Anatomical Properties of Juvenile Latex Timber Clone Rubberwood Trees Junaiza Ahmad Zaki, Suhaimi Muhammed, Shaikh Abdul Karim Yamani, Amran Shafie and Wan Daud Wanrosli Abstract At present, Malaysian furniture industries are dependent on the rubberwood (Hevea brasiliensis) species and are also highly demanded by other wood-based industry. This is because, the wood properties of rubberwood such as whitish color and good machining properties make it suitable in producing furniture and furthermore rubberwood is also known as “Malaysian Oak” or “White Mahogany” as a trade name. Due to that, Lembaga Getah Malaysia (LGM) had introduced the latex timber clone (LTC) at early years of 2000s to overcome the shortage of rubberwood. In this research, the anatomical aspect of tree heights and distances from near bark to near pith for two different types of latex timber clones (RRIM 2009 and RRIM 2024) of the same age between 3–4 years was investigated. The results for vessel frequency and vessel diameter showed no significant difference for clone and the distance from near bark to near pith except for tree height where the vessel frequency at the top portion is greater and the bottom portion gave a higher number for vessel diameter because both characteristics were related to each other. With regards to vessel frequency, RRIM 2024 clone register a higher value as compared to RRIM 2009. Overall, this study found that the RRIM 2024 clone showed better growth performance compared to RRIM 2009 clone. Keywords Anatomical

1 Introduction Wood is natural resources and play very important role in human daily life. It is used as furniture, fiberboard, pulp and paper, plywood, and also has value for wood construction. Therefore, wood anatomy is a fundamental knowledge in the field of wood science and technology. Wood identification through its physical or structural features will be able to provide the information or the uniqueness of the wood that can be applied into a product. Rubberwood species (Hevea brasiliensis) are from Euphorbiaceae family. This species was brought to Kuala Kangsar, Perak in 1877. The creamy to whitish color of rubberwood and its straight grain (Hong and Sim 1994) make it an important resource for the production of furniture and other products such as stairs, parquet floor, blockboard, medium density board, and wall paneling.
