“…Wight & Arn is a specie that belongs to the Fabaceae family, and popularly known as Indian cedar. This species is native to tropical regions of Asia, such as India, Myanmar (Burma) and Bangladesh (Carvalho 2010) and is widely used in civil construction, in the furniture industry and the manu-facture of cellulose and paper (Trianoski et al 2011, Firmino et al 2015.…”

Indian cedar (Acrocarpus fraxinifolius) is a wood species that occurs naturally in India, Myanmar (Burma) and Bangladesh, and has a high commercial value, with characteristics like mahogany and native cedars. The planting of Indian cedar has been undertaken in Brazil, but there is little information available regarding the characterization of the species. Therefore, considering its timber potential and its possibility of development in the country, the present work aimed to evaluate the physical, chemical, and mechanical properties of 9-year-old Indian cedar wood, planted in the southern region of Brazil. A low specific mass (502 kg/m³), low average dimensional stability (anisotropy coefficient of 2,09 %) was observed, in addition to the low content of extractives (1,94 %). From the mechanical characterization, an average value for the elastic modulus of 8963 MPa was obtained, and for the compressive strength parallel to the grain the average and characteristic values were 32,14 MPa and 21,46 MPa, respectively. This indicates that this wood belongs to resistance class C20 (dicotyledons). The results obtained classify the wood for use in light, external, or internal civil construction

Aiming to provide greater visibility for the wood species Acrocarpus fraxinifolius, the present study sought to analyze the influence of heat treatment on an industrial scale applied to wood species, also popularly known as Indian cedar. The heat treatment was carried out in an autoclave, with temperature and pressure control, and with saturated steam injection, for temperatures 155 ºC, 165 ºC, 175 ºC, and 185 ºC. Physical, chemical, and mechanical tests were carried out for the analyzed wood. The content of holocellulose and total lignin decreased, while the content of extractives showed a substantial increase. The density increased after the heat treatment, however the treated wood showed cracks, and these cracks influenced the significant loss of the values of the mechanical properties of compression, tension, and flexion. The shear showed strength gain for the temperature of 155 ºC, and the wood treated at 165 ºC was equivalent to untreated wood. The woods submitted to temperatures of 175 ºC and 185 ºC presented strength losses. The heat treatment in question contributes to increase the visibility, use and market value of wood.

“…Acrocarpus fraxinifolius Wight & Arn belongs to the Fabaceae family, Caesalpinioideae subfamily, and it is popularly known as Pink cedar. It produces a reddishbrown hard wood used for construction, furniture and pulp production (Firmino et al, 2015). It is native to high rainfall regions of Asia, has rapid growth, it is very promising for reforestation, and used for producing short rotation timber (Trianoski et al, 2011).…”

Morphological, anatomical and physiological characteristics of Acrocarpus fraxinifolius Wight & Arn seedlings according to containers and fertilization. CERNE, v. 24, n. 4, p. 430-438, 2018. HIGHLIGHTS Acrocarpus fraxinifolius plants show increased growth and stem diameter when grown in 110 cm 3 tubes. Photosynthetic rate (A), stomatal conductance (gs) and transpiration (E) of Acrocarpus fraxinifolius in 110 cm³ tubes were similar to well-fertilized 50 cm³ tubes. The plants demonstrated expansion of Parenchyma cells with greater mesophyll thickness.
