Boring Boring operations are reported to be fair. Planing This species is easy to plane. 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.

Poles 3 – Estudo dendrologico e determinacao das caracteristicas fisicas e mecanicas do genipapo Genipa americana. 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.

It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations. The boles are often straight and cylindrical, covered with a typically ridged bark.

This first senescent leaves caused insect mortality. Parquet 15 – Empire Timbers. Sspidosperma Packing 47 – Arvores Brasileiras. Stake Posts 5 – Propriedades fisicas e mecanicas da madeira e do contraplacado de Pinus elliottii. Crossties 8 – Maderas latinoamericas. A population of Aspidosperma macrocarpon Apocynaceae with leaf galls induced by a Pseudophacopteron sp. Aspidosperma species exudate a milk.


The leaves were infested in October, galls developed along the year, and gall senescence took place from March to September, together aspidpsperma host leaves.

It is considered to be moderately difficult to season Aspiidosperma Defects: Moulding Molding operations are fair. Luster Luster is moderate to high. Odor typical odor, bitter taste. In Peru cupping is reported. Furniture Cabinets 21 – Tropical timbers of the world.

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.

Vessels per mm2 10 to 20 abundant. The phenology, infestation of galls, macrocsrpon the carbohydrate and nitrogen contents were monthly evaluated in individuals, from September to September Steps 17 – Tree Conservation Database.

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. Grain It has interlocked grain.

The joint interpretation of phenology and nutritional metabolism provides important data on plant tissues reactivity and the period of gall induction. Wood Macro Photo Radial Plane.

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.


Fibers with distinctly bordered pits. Basic Density or Specific Gravity O.

In Brazil, the range for this species is the cerrado forests. The nutrients were previously consumed by the growing leaves, by the time of gall induction. Color The sapwood is yellow, the heartwood is reddish yellow color. General Housing 10 – Silica in Timbers. Rays more than macrocxrpon per mm abundant.

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. Exterior General 1 – Tabela de resultados de ensaios fisicos e mecanicos.

Texture Fine texture is reported in this species. Flooring 14 – Handbook of Hardwoods. Careful drying is recommended. Drying Defects Ease of Drying: The levels of carbohydrates were higher in galls than in non-galled leaves in time-based analyses, which indicateed their potential sink functionality. Natural Habitat It is found in lowland and low elevation montane rain forests up to m of altitude, in primary and secondary formations.
