Description and Uses
Pinus merkusii (Merkus pine) is a
tropical
tree from
South East Asia . 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
18 -
22 years. The yield will be
{missing data}, but in its top season there will be a yield of
{missing data}. Other crop types include;
timber, fuel, ornamental, gum resin, . The
{missing data} is used as
{missing data} . The
{missing data} is used as "
{missing data} " with
{missing data} ({missing data} -
{missing data}) as its significant
phytochemical. There is
{missing data} extracted by
{missing data} from the
tree's
{missing data} yielding
{missing data} -
{missing data} oil. The
tree's wood is called
{missing data} and has a density of
530 -
560 kg/m³. Regarding firewood production the
tree's growing speed is
fast, it's energetic value is
5100 ckal/kg and the wood's drying speed is
{missing data}. After
25 years the
tree can be totally removed as it reached its commercial and ecological goal.
Pinus merkusii has a lifespan of
300 years.
Environmental limitations
The tree is
60 meters tall with a crown of
22 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.
Pinus merkusii has a
shallow root-system and it has symbiotic associations with the
fungi
(ecto-mycorrhiza). It is
not able to fix nitrogen with
"any bacteria. The name(s) or string of bacteria include(s)
"not applicable ". The
tree's flower-morphology is
hermaphroditic and is pollinated by
wind.
Pinus merkusii is
{missing data} and
a bit allelopathic and has
no thorns.
Pinus merkusii thrives in an altitude of
0 to
2000 meters above sea-level
(tropical). The minimum temperature is
6°C; optimally between
21 -
28°C. The optimal rainfall is
