DESCRIÇÃO DA ÁRVORE
Descrição botânica
A medium to large-sized tree of up to 30 m tall, bole often crooked and branchless for 3-10 m, with a diameter of up to 100 cm, and very often without buttresses. In drier area, the trees remain a comparatively small.
Habitat natural
D. sissoo grows gregarious on well-drained colluvial and alluvial soils, often near rivers and streams up to 900 m altitude. Stands of Dalbergia trees have been depleted considerably all over the world.
Distribuição natural
D. sissoo occurs throughout sub-Himalayan tract, from the Indus to Assam. Planted trees are found in mainland South-East Asia, Java and Africa.
Existência de plantações?
The tree has been extensively planted on many parts of India, and, on a much smaller scale in Java (Indonesia).
Usos não madeiravéis
Medium-weight to heavy hardwood. The specific gravity of Sissoo wood is 0.63-0.83 at air-dry condition.
IDENTIFICAÇÃO DA MADEIRA
Descrição anatômica da madeira (macro e micro)
Vessels per mm2 6 to 10 (medium). Wood diffuse porous. Occasionally vessels of two distinct diameter classes, wood not ring-porous. Resinous deposits in heartwood vessels. Tangential diameter of vessel lumina 200 micras or more (large). Axial parenchyma winged aliform (uni or bilateral winged). Axial parenchyma confluent. Occasionally axial parenchyma in marginal or in seemingly marginal bands. Axial parenchyma in discontinuous tangential lines. Rays storied. Rays more than 10 per mm (abundant). Rays 1 to 2 seriate.

DESCRIÇÃO GERAL DA MADEIRA
Odor ou Cheiro
-
Cor
Heartwood is golden brown to deep red-brown, often with darker streaks which giving rise to an attractive figure, distinctly demarcated from the whitish to yellowish or pale brown colored narrow sapwood.

Defeitos causados pela secagem
Ease of Drying: Board can be fully kiln dried under moderately severe conditions with any slight tendency to twist readily eliminated by weighting and giving short steaming treatment after drying.Limited appraisal of 50 mm stock indicates satisfactory results will gener Drying Defects: 25 mm board:Kiln drying time from green to 12 % m.c. is about 4-5days, reduced to 2 days if preliminary air drying to 30%m.c. is undertaken. A short steaming treatment of 2-3 hours under weights is recommended at end of drying to relieve drying stresses
