Resumo(s)
Tropical species are highly valued timber sources showing a large diversity of wood
characteristics. Since there are major concerns regarding the sustainability of these tropical species
in many tropical regions, knowledge of the variability in wood properties is therefore a valuable
tool to design targeted exploitation and to enlarge the wood resources base, namely by identifying
alternatives for CITES-listed species. In this study, 98 tropical wood species belonging to 73 genera
from India, Mozambique, and East Timor were investigated regarding wood anatomy and physical
properties. Numerical taxonomy, by means of cluster analysis and principal component analysis
grouped species with anatomical and physical similarities from different geographical origins. In
addition to wood density, ray and vessel characteristics as well as wood moisture and wood shrinkage
properties explained the main variability of these species. The contribution of wood color patterns
was highlighted as consistently separating the Mozambique woods. A distinct geographical pattern
was not observed, reinforcing that species from India, Mozambique, and East Timor show similar
anatomical and physical wood properties, which could be useful to increase timber trade diversity.
The multivariate analysis showed that species from Mozambique, such as Morus mesozygia, and
Millettia stuhlmannii and Swartzia madagascariensis, could be alternatives for the CITES-listed species
Cedrela odorata and Dalbergia melanoxylon, respectively
