Rubber Tree Cultivation and Improvement in Malaysia: Anatomical and Morphological Studies on Hevea brasiliensis and Hevea camargoana

Rubber trees are among the important cultivated crops in Malaysia, and have contributed to the country’s overall economic growth since the 1950s. However, the existing anatomical and morphological studies are relatively insufficient. Currently, Hevea brasiliensis has been cultivated and planted commonly as a commercial planting clone, while Hevea camargoana remains to be a non-cultivated and underutilized rubber species. For many years, there only exists little information both in private plantations and government agencies that have carried out anatomical and morphological assessments on these underutilized species. There is little information about the characteristics of H.camargoana, thus raising the issue among plant breeders on how to best use this underutilized rubber species. This study attempts to investigate the taxonomic values and characteristics of Hevea brasiliensis and Hevea camargoana through anatomical and morphological studies.
