Sawing Cutting resistance is generally low. The nutrients were previously consumed by the growing leaves, by the time of gall induction.

In Peru cupping is reported. It is aspidopserma to be moderately difficult to season Drying Defects: Fibers with distinctly bordered pits. Botanical Description The size of the mature tree is reported to be small to medium, attaining heights up to 20 to 30 m, and diameters of about 40 to 60 cm.

Color The sapwood is yellow, maceocarpon heartwood is reddish yellow color. Assuming the morphological similarity between host leaves and intralaminar galls, a gradient from non-galled leaves towards galls should be generated, aspidowperma a morpho-physiological continuum. The joint interpretation of phenology and nutritional metabolism provides important data on plant tissues reactivity and the period of gall induction. The leaves were infested in October, galls developed along the year, and gall senescence took place from March to September, together with host leaves.

Odor typical odor, bitter taste. The boles are often straight and cylindrical, covered with a typically ridged bark. This first senescent leaves caused insect mortality. It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations.

Vessel-ray pits similar to intervessel pits in size and shape. General Housing 10 – Silica in Timbers. Drying Defects Ease of Drying: The period of leaf flushing coincided with the highest levels of nitrogen allocated to the new leaves, and to the lowest levels of carbohydrates.

Tangential diameter of vessel lumina micras or less very small. Scientific Name Aspidosperma macrocarpon Mart. Grain It has interlocked grain.

ARARACANGA (Aspidosperma macrocarpon)

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. Basic Density or Specific Gravity O. The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their potential sink functionality.
