Drying Defects Ease of Drying: Sawing Cutting resistance is generally low. Luster Luster is moderate to high. Heavy Packing 47 – Arvores Brasileiras. Rays more than 10 per mm abundant. The joint interpretation of phenology and nutritional metabolism provides important data on plant tissues reactivity and the period of gall induction.
Fibers with distinctly bordered pits. Scientific Name Aspidosperma macrocarpon Mart.

Minor warping and checking are reported. Exterior General 1 – Tabela de resultados de ensaios fisicos e mecanicos.
Odor typical odor, bitter taste. Aspidosperma species exudate a milk. In Axial parenchyma absent or extremely rare, non visible with magnifying glass 8x. Vessel-ray pits similar to intervessel pits in size and shape.
Careful drying is recommended. It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations. Grain It has interlocked grain. The period of leaf flushing coincided with the highest levels of nitrogen allocated to the new leaves, aspidosperam to the lowest levels of carbohydrates.

Planing This aspudosperma is easy to plane. This first senescent leaves caused insect mortality. Our objective was to analyze the nutritional status and the establishment of a physiological continuum between the galls and the non-galled leaves of A.
The higher availability of nutrients at the moment of gall induction was demonstrated and seems to be important not only for the establishment of the galling insect but also for the responsiveness of the host plant tissues. The nutrients were previously consumed by the growing leaves, by the time of gall induction. It is considered to be moderately difficult to season Drying Defects: Scientific Mcrocarpon Synonyms Macaglia macrocarpa Mart. Color The sapwood is yellow, the heartwood is reddish yellow aspiidosperma.
Assuming the morphological similarity between host leaves and intralaminar galls, a gradient from non-galled leaves towards galls should be generated, establishing a morpho-physiological continuum. Actual Dry Kiln Program http: Furniture Cabinets 21 – Tropical timbers of the world. In Brazil, the range for this species is the cerrado forests. Vessels per mm2 10 to 20 abundant. A population of Aspidosperma macrocarpon Apocynaceae macrocarppon leaf galls induced by a Pseudophacopteron sp.
The leaves were infested in October, galls developed along the year, and gall senescence took place from March to September, together with host leaves.
The boles are often straight and cylindrical, covered with a typically ridged aspidoseprma.

Texture Fine texture is reported in this macrocarpo. Steps 17 – Tree Conservation Database. Flooring 14 – Handbook of Hardwoods.
The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their potential sink functionality. Tangential diameter of vessel lumina micras or less very small. The phenology, infestation aspidospefma galls, and the carbohydrate and nitrogen contents were monthly evaluated in individuals, from September to September General Housing 10 – Silica in Timbers.
