Although the number of individuals of Aquilaria spp exhausted, but demand for Agarwood in the world trade increased substantial. At present, the strongest countries are Middle East and Asia, and even in the US and Europe (TRP, 1997). Article below shall give some profound knowledgement about natural origin of Agarwood.
Two following agarwood types can be categorized:
- Agarwood derived from the living tree
- Agarwood obtained from the felling tree or tree dying for a long time).
Type 1. Agarwood from living plants are usually light color while the other type they are usually glued, or black. Often people take tortoise from the root. The price of Type 1 is usually as 2-3 times higher than Type 2. Each type can be harvested per tree 5-10kg of Agarwood. In addition, the scattered appearances of the Agaric interspersed with wood, according to Phillips (1997), the types of Agarwood and Agarwood products are noted on The market is: Agarwood chips, Agarwood powder, Agarwood essential oil (For aromatherapy and medicinal purposes).
The analysis of Agarwood and Agarwood products was conducted by Erhartdt, Le Cong Thuan, and Hopwood (1997) performed by gas chromatography combined with mass spectrometry (Gas Chromatography / Mass Spectrometry). Note that two sesquiterpenes exist in commoning wood as well as in essential oils, which are (+) -Andendrene and -Selinene. However, Selinene does not appear in low-grade acacia wood. On the other hand, Guaiene, another Sesquiterpene is found in the natural acacia wood but only in the specimen Oil, whereas Guriunene, an isomer of Aromadendrene has many of the patterns. Essential oils but not found in natural wood samples.
Until now, there are a few work’s research on creation. However, the transport use a knowledge make sure way of mechanism creating Agarwood for production. Aging in a sustainable way is still challenging with scientists. Physically until now, there is no complete experiment, although there are several scattered. The trial was conducted on young seedlings grown in the medium control. According to Pham Hoang Ho (1985)
The origin of the disease has only been known in recent years. Survey of Julaluddin (1977) suggested that the Tok region contained a fungus that was identified Cryptosphaeria mangifera. He determined the appearance of agarwood resin by letting the gourd tree be under strong fungal infection. After a while, the infected area becomes dark and becomes TokIt is very pronounced when it is burned. However, these are just the beginning of Agar formation.
Agarwood can appear on the tree is big or small. In fact, many gourds are large, with a diameter of 50-60cm but without Agarwood. On the contrary, the new seedlings are only 15cm in diameter with Agarwood. Recent experiments. It can be seen that Agarwood can be stimulated in 4-5-year-old trees. On the big trees, old Agarwood resin appears more and more. According to folklore, it is possible to distinguish trees that have been planted through some morphological characteristics of trees. The conditions of the place where it grows are as follows:
The tree has a diameter of more than 20cm.
Branches with tumors, many plants, diseased or injured plants.
Barren, yellowish green.
Harder to peel than normal trees.
Yellow wood.
Trees grow on bad soil with many stones.
Agarwood appears in three places: roots, roots, branches, branches at the height over 60cm above the ground rarely have Agarwood. Much of the incense lies around the root, especially in the roots. Therefore, when looking for agarwood resin, roots are growing to the right dug up there. Seekers are not afraid of snake bites because they believe that when there is Snake snakes. He was sent away.
Most recently, the European Rainforest Research team combined with the University of Natural Sciences and two provinces of Kien Giang and An Giang research program to create Agarwood from seedlings grown in seeds Phu Quoc.
