Apparently 8-10 year-old trees have poor wood quality, both for fiber and sawnwood. Is there any change with age from softwood to heartwood proportions?
Dear Mauricio Jerez,
Please have a look at these useful PDF attachments.
Good luck
Thank you Arvind!.
From your papers and other readings, Acrocarpus timber appears to be useful for several uses. Wood properties of timber from young trees are acceptable for mixing with other species´s timber to make particleboards, etc. However, for sawnwood, the proportion of heartwood appears to be very important, as heartwood has better properties than softwood . By 13.5 yr-old, trees show up to 30% heartwood. This makes me think that sawnwood quality wood could be obtained at ages close to 18-20 years.
In Latin america this species is being used for agroforestry systems in small scale plantations. Use of this species other than for sawnwood in these systems could be unatractive for farm owners given that very low prices would be offered. To be attractive for sawtimber, appropriate knowledge of how to work this timber exists, but it is not widespread. Technological limitations of sawmills ( in Latin America) could courtail the future use of this species, at least in agroforestry. I attach a couple of interesting works in Acrocapus. A paper in English-Spanish on volume equations for this species, and a Thesis (in Spanish) about the performance of this species subjected to sawtimber workability tests. Regards.
Dear Mauricio Jerez,
Thanks for sharing useful information and resources relating to wood properties of Acrocarpus fraxinifolius.
