Anatomi kayu gaharu (Aquilaria malaccensis Lamk.) dan beberapa jenis sekerabat

Anatomical characteristics of five 'gaharu' wood species, aquilaria malaccensis, Aetoxylon sympetalum, Gonystylus macrophyllus, and Gyrinops versteeghii were described and compared, to find out how to identify and differentiate gaharu wood by their taxa. The knowledge of the difference between Aquilaria malaccensis, which has been listed in Appendix II CITES, from other gaharu wood that have not been listed, would be advantages in supporting the conservation on A. malaccensis as well as in promoting the utilization of the other gaharu wood species. The result of study indicated that all gaharu wood examined have several same features : 1) fibers with distinctly borderd pit at radial face and tend to be arranged in two series, 2) inteeeervessel pit small, 4 - 7 microns, 3) rays of commonly uniseriate. Both Aquilaria malaccensis and Gyrinops versteeghii have included phloem, while the other tree gaharu wood species do not contain included phloem. Aquilaria malaccensis that has been listed in Appendix II CITES could be differentiated from Gyrinops versteeghii based on vessel characteristics. Aquilaria malaccensis has medium vessel diameter, 100 - 200 mocrons, frequency less than 10 vessels per sq.mm, and radial multiples of 2 - 4 cells. Gyrinops versteeghii has moderately small vessel diameter, less than 100 microns, frequency more than 10 vessels per sq. mm, and radial multiples of 2 - 6 cells. Aetoxylon sympetalum and Gnnystylus spp. are together characterized by the presence of aliform and confluent parenchyma and the occurence of prismatic and styloid crystals in rays of 1 - 2 to 3 seriate wide, could be used to differentiate Aetoxylon sympetalum from Gonystylus ssp. The latter have fibers of medium thickness and rays of commonly uniseriate.
