The objective of planting Aquilaria is the production of quality resinous wood from young plantation-grown trees.

If no such wood is found within the tree…
….it has very little economic value.
A healthy aquilaria tree without oleoresin is a mere Sg=0.38.
(Water is having Sg=1, Rubberwood Sg=0.56~0.64 , Teak Sg=0.63~0.72 )
Anything having Sg<1 will float when put into the water. Wood without oleoresin is not even valuable to be used as firewood.
