[en] It is important to get the right planting material and or seedling to clonally propagate starter sources. Commercial planting of Aquilaria spp. in Malaysia is carried out for downstream purposes and is currently becoming a big industry for gaharu resin production. Planters will buy purportedly good quality Aquilaria seedlings from an established nursery without knowing if the seedlings could produce high quality resin at maturity. The easiest way to identify Aquilaria species is through their morphological characteristics or the phenotypic characterization of the leaves, stems or trunks, flowers and fruits. (author)
