Description and Uses
Pentaclethra macroloba (Fine leaf tree) is a
tropical
tree from
Amazone . It is mainly grown for its
oil crops
, which have a
long shelf life. The crop is harvested by
ground gathering. It starts flowering after
2 -
5 years. The yield will be
?, but in its top season there will be a yield of
?. Other crop types include;
timber, fuel, ornamental, nut, oil, poison herbicide, cosmetics. The
{missing data} is used as
{missing data} . The
seed/nut is used as "
anti heart failures, " with
behenic acid (19%/oil -
20%/oil) as its significant
phytochemical. There is
Pracaxi oil extracted by
cold pressing from the
tree's
seed/nut yielding
45% -
48% oil. The
tree's wood is called
pracaxi wood and has a density of
750 -
850 kg/m³. Regarding firewood production the
tree's growing speed is
fast, it's energetic value is
4900 ckal/kg and the wood's drying speed is
medium. After
70 years the
tree can be totally removed as it reached its commercial and ecological goal.
Pentaclethra macroloba has a lifespan of
350 years.
Environmental limitations
The tree is
38 meters tall with a crown of
14 meters wide. The
tree prefers a planting distance of
600 cm and a row distance of
600 cm. It is
very fast growing and
shade tolerant.
Pentaclethra macroloba has a
deep root-system and it has symbiotic associations with the
Glomus hoi and Glomus intraradices and Glomus mosseae fungi
(endo-mycorrhiza). It is
able to fix nitrogen moderately with
"Rhizobiaceae bacteria. The name(s) or string of bacteria include(s)
"not applicable ". The
tree's flower-morphology is
hermaphroditic and is pollinated by
insects.
Pentaclethra macroloba is
{missing data} and
not allelopathic and has
no thorns.
Pentaclethra macroloba thrives in an altitude of
0 to
600 meters above sea-level
(tropical). The minimum temperature is
10°C; optimally between
20 -
35°C. The optimal rainfall is
5500
mm/year. Without irrigation the annual rainfall should be between
2500 -
6000mm (L/m²). The optimal soil-pH is between
4.0 -
6.0 in a soil texture of
water. To salt it is
intolerant to wind
intolerant and to fire
intolerant.

Seed Propagation
Seeds are
intermediate and can be stored for
1 months. There are approximative
300
seeds/kg. The seeds can be propagated as followed:
- (1) Store harvested seeds in water or in the fruit at room temperature
- (3) Remove the seeds from cold to a permanent warm temperature.
- (3) Seeds germinate above ground (epigeous)
