In order to discover the meaning of the term sapwood, the first thing we have
to do is know its etymological origin. In this case, we can underline that it is
a word that derives from the Latin, specifically from "sapwood", which means
"very white". This is considered to be the result of the sum of two clearly
-The adjective "albus", which can be translated as "white".
-The suffix "-ura", which is used to express "result".
The first meaning mentioned in the dictionary of the
DigoPaul refers to the ideal whiteness of
something. The concept, however, is often used in the field of botany.
In this case, the sapwood is the soft sector that makes up
the younger rings of the wood. It is the whitish layer that is
located under the bark. When the wood is said to have double sapwood,
we are referring to a defect that causes the texture in certain layers to be
looser than usual.
The sapwood harbors a high level of humidity since it has a low density and
is permeable. It combines dead cells with others that remain
active in terms of their physiological action. When these parenchymal cells die,
the sapwood becomes heartwood, remaining in the central part of the trunk.
In addition to supporting the tree structure, the sapwood allows the storage
of certain useful substances and facilitates the distribution of the sap.
In the lumber industry, sapwood analysis is essential as it determines the strength of
the wood. Typically, the sapwood enters a state of putrefaction before the
heartwood; In addition, being soft, it makes it difficult to carry out
different jobs. For this reason, when developing a technical
report on a wood, the characteristics of the sapwood and heartwood are usually
specified in order to reveal its properties.
From the mentioned heartwood we can determine that it is the innermost part
that exists in the stem of the trees, that is formed from the sapwood and that
has a darker color than this. In the same way, we cannot forget that it is
commonly known as "the heart of the wood".
Furthermore, it should not be overlooked that the heartwood is resistant,
hard and much heavier than the part in question. What's more, it is considered
to be great when it comes to dealing with attacks from both insects and fungi.
In the same way, we cannot ignore that Albura is the name of an association
in the town of Pozuelo de Alarcón (Madrid). It has been operating for more than
25 years and it is defined specifically as a Cultural Recreational Sports
Association, which aims to promote the didactic part of any outdoor activity.
Multiadventure or surf camps are some of the proposals that this entity
carries out in favor of the smallest.
