Wood Qualities of Some Tropical Plantation Species — Does Hastening the Growth Debase the Quality?
It is the most important and an urgent task for humankind to establish the consistency between maintenance of global environment and sustainable supply of forest resources. In order to accomplish this task it is very important to encourage establishing forest plantations especially in the tropical regions. Recently, plantation forests have become very common in many tropical countries . These plantations mainly aim to produce short rotation raw materials for pulp and paper. However to make this effort successful, it is necessary to establish an economical cycle between producer and consumer sectors by raising the added value of the plantation species. Developing timber use of the species is an essential way to raise the economical value of the short rotation trees. The growth rate of the tropical plantation species is faster than that of Temperate Zone species. Therefore, it is worried about that the inferior qualities due to the larger growth rate will take place during lumber processing. This investigation is focused mainly to the growth stress because the growth stress is the most important obstacle facing in the first place at sawing. Better understanding of the growth stress will contribute to raising timber value by linking the genetic improvement of tree, better afforestation technology and improved wood processing technologies . From the above background, we have been conducting investigation on the effect of extremely high growth rate upon the growth stress and other properties of plantation species in Indonesia.
