Description and Uses
Pterogyne nitens (Viraro tree) is a
tropical
tree from
Amazone . It is mainly grown for its
timber crops
, which have a
medium shelf life. The crop is harvested by
total removing. It starts flowering after
0 -
0 years. The yield will be
_, but in its top season there will be a yield of

timber, fuel, ornamental, mulch, . The

tree's wood is called
{missing data} and has a density of
650 -
680 kg/m³. Regarding firewood production the
tree's growing speed is
fast, it's energetic value is
4700 ckal/kg and the wood's drying speed is
fast. After
35 years the
tree can be totally removed as it reached its commercial and ecological goal.
Pterogyne nitens has a lifespan of
90 years.
Environmental limitations
The tree is
27 meters tall with a crown of
16 meters wide. The
tree prefers a planting distance of
600 cm and a row distance of
600 cm. It is
very fast growing and
intolerant to shade.
Pterogyne nitens has a
deep root-system and it has symbiotic associations with the
fungi
(endo-mycorrhiza). It is
able to fix nitrogen moderately with
"Microbacteriaceae bacteria. The name(s) or string of bacteria include(s)
"not applicable ". The
tree's flower-morphology is
hermaphroditic and is pollinated by
insects.
Pterogyne nitens is
evergreen and
not allelopathic and has
no thorns.
Pterogyne nitens thrives in an altitude of
300 to
1100 meters above sea-level
(tropical). The minimum temperature is
7°C; optimally between
18 -
30°C. The optimal rainfall is
1350
mm/year. Without irrigation the annual rainfall should be between
700 -
1300mm (L/m²). The optimal soil-pH is between
5.0 -
7.0 in a soil texture of
loam. To salt it is
a bit tolerant to wind
tolerant and to fire
intolerant.
