Description and Uses
Schizolobium parahybum (Brazilian fern tree) is a
tropical
tree from
Colombia & Venezuela . 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
2 -
3 years. The yield will be
600 m3/ha/10yr, but in its top season there will be a yield of
{missing data}. Other crop types include;
bio-mass, fuel, paper pulp, timber, . The
{missing data} is used as
inedible . The
fresh leaf is used as "
anti-poison, " with
{missing data} (? -

phytochemical. There is
{missing data} extracted by
{missing data} from the

{missing data} yielding
{missing data} -
{missing data} oil. The
tree's wood is called
Brazilian ferntree wood and has a density of
320 -
390 kg/m³. Regarding firewood production the
tree's growing speed is
very fast, it's energetic value is
4513 ckal/kg and the wood's drying speed is
slow. After
10 years the
tree can be totally removed as it reached its commercial and ecological goal.
Schizolobium parahybum has a lifespan of
45 years.
Environmental limitations
The tree is
0 meters tall with a crown of
0 meters wide. The
tree prefers a planting distance of
600 cm and a row distance of
600 cm. It is
very fast growing and
partial shade tolerant.
Schizolobium parahybum has a
shallow root-system and it has symbiotic associations with the
Acaulospora longula and Acaulospora scrobiculata and Acaulospora tuberculata and Claroideoglomus etunicatum and Glomus clarum and Glomus intraradices fungi
(endo-mycorrhiza). It is
not able to fix nitrogen with
"Rhizobiaceae bacteria. The name(s) or string of bacteria include(s)
"Rhizobium huautlense ". The
tree's flower-morphology is
androdioecious and is pollinated by
bees.
Schizolobium parahybum is
deciduous in dry season and
a bit allelopathic and has
no thorns.
Schizolobium parahybum thrives in an altitude of
0 to
500 meters above sea-level
(tropical). The minimum temperature is
7°C; optimally between
20 -
26°C. The optimal rainfall is

6.0 -
7.0 in a soil texture of
sand. To salt it is
a bit tolerant to wind
a bit tolerant and to fire
a bit tolerant.
