The texture is coarse to very coarse; the grain mostly irregular; lustre usually medium; it ormosia arborea harsh; there is no distinctive odour or taste. The wood is generally reported to be quite susceptible to attack by decay fungi; ormosia arborea is vulnerable to dry-wood termites, and prone to powder-post beetle attack sapwood.

It generally air dries very slowly; checking and warp vary from slight to moderate. The greatest root length was observed in the seeds scarified chemically with acid or mechanically with number 50 or sandpaper Figure 3 a. The use of organic solvents like alcohol and acetone removes the waxy layer of the seeds of many species.
Root a and aerial part b lengths of Ormosia arborea seedlings submitted to different dormancy breaking treatments. The same behavior observed ormosia arborea the other tests of this study was shown in the seedling aerial ormosia arborea length. Seeds scarified mechanically with sandpaper and chemically with sulfuric acid resulted in well-developed seedlings Figure 3 b.

These differed statistically from those that were submitted to heat and soaking. The root and aerial part dry mass data is presented in Figure 4. Seeds scarified with sandpaper or sulfuric ormosia arborea had the greater root and ormosia arborea part dry mass Figures 4 a and 4 b.
Dry root a and aerial part b mass of Ormosia arborea seedlings submitted to different dormancy breaking treatments. Discussion The ormosia arborea is dormant due to tegument impermeability, which can be overcome by chemical or physical scarification by scarification.
The acid and sandpaper treatments used promoted the seed tegument rupturing, facilitating ormosia arborea entrance of water and consequently favoring germination.
Therefore, the imbibition is essentially a physical process related to the characteristics of seed coat permeability and properties of colloids of the seeds, whose hydration is one of its first consequences. The treatments for dormancy breaking tegumentary seed ormosia arborea efficient because they promoted the rupture of the impermeable layer in the case of physical scarification or distributing pores in the integument when ormosia arborea sulfuric acid used, thus, enhancing the water absorption by seed and triggering the germination process.
Several studies have been made with the mechanical scarification being shown as an efficient dormancy breaking method ormosia arborea provoke germination in Astragalus siliquosus seeds [ 14 ]. The scientific name Ormosia is a nomen conservandumoverruling Ormosia arborea which is formally rejected under the International Code of Nomenclature for algae, fungi, and plants.
They resemble the seeds of Abrussnoutbeans Rhynchosiaand Adenantherabut are much larger than the former two. In particular those of Ormosia coccinea are often used for jewelry and other decorative purposes, or as good luck charms.
