(Nothofagus dombeyi)
 
Uses
It is used in big works like bridges, wharves,
pools and others. In houses is used to make floors, parquets, concrete
container, coatings. In rail road ties, boats and in place diagonally
plate manufacture. In carpentry it is used for furniture, drawers, packages,
toys, skis, etc.
Qualities
We have wood of coihue parked.
Description
Coihue, the most frequent and characteristic tree in our landscape,
lives almost from the level of the sea to the superior limit of the
arboreal vegetation, preferring drained grounds affluents. Within the
forest, the coihue appears like a dominant species that unfolds its
glass to greater height than the other species. It measures more than
40 meters tall and their trunks are proportionally
strong. Coihue forms great broadcast branches that arrange the foliage
in the horizontal layers that are characteristic of their habit. The
leaf is small, of about 3 cm in length. They shine to the sun by a natural
varnish whom they have in his superior part. It is a beautiful tree,
of great branches and a solemn, sometimes festive aspect, with much
ornamental value. It is in addition a good windstopper.
 The
Coihue has flowers of both sex. The female flowers meet in groups of three
and give origin to cupolas that contain three
small nuts. These seeds, of which it can
have 200 to 500 thousands by kg, according to the variety, easily are
dispersed by the wind. The property of being strong
supports the characteristics of coihue´s pioneer, frequently one
of the first species in colonizing open spaces by landslides or other
phenomena.
The Coihue has an annual reproductive cycle: it begins in spring with
the flowering and finishes in the following autumn
(April to May) with the dispersation of the seeds. These seeds are of
epígea germination, that means, hipocotilo emerges along with by
on the ground cotiledones. Arrived at a certain level, the seminal cover
falls and the first normal leaves are developed. He is interesting to
notice that the small coihue
plants can grow on fallen trunks taking
advantage of small humus
amounts. This capacity helps the coihue, that is
intolerante in the shade, to prevail over quila and other species that
emerge from the ground.
Like
main arboreal species of the region, coihue is a masterful beam of the
ecological, basic system for the existence of many other species.
