Variation of wood properties and wood quality

• Caesalpinia platyloba („Chacte – viga“) and Cordia dodecandra

(„Siricote“) are two native tree species in Mexico. Both are not used

for plantations.

• valuable tree species producing wood with good characteristics and

properties;

• wood is currently used in building constructions, railway sleepers,

high quality furniture and handcrafts;

• the wood of both species shows a good possibility for the export to

the global market (especially Europe);

Objectives

Wood samples from different provenances (site conditions);

Forest inventory data are available

Investigations into: heartwood portion

heartwood colour

wood anatomy

physical properties (density, shrinkage)

mechanical properties (bending, hardness)

natural durability

Thank you for your attention

The results will be presented in the

next meeting
