GLOSSARY OF TERMS USED  
 

Astringent

Med.: a substance which contracts the tissues or canals, thereby diminishing discharges (blood, etc)

Board

Part of the bark cork having the length of the trunk stripped and a width of half or 1/3 of the tree circumference. The back of the board is the external part containing the crust. The belly is the internal part which was in contact with the trunk (phellogen)

Cambium

A layer of delicate meristem atic tissue cells that elaborates the wooden cell, between the inner bark or phloem and the wood or xylem, which produces new phloem on the outside and new xylem on the inside in stems, roots, etc. It produces all secondary growth in plants, trees and is responsible for the annual rings in wood.
In the cambium circulates the raw sap coming from the root in direction of the upper part of the tree.

Desiccation

Operation eliminating the dampness in the body of the cork

Excrescence

Abnormal outgrowth usually harmless, on an animal or vegetables body

Facing

Cutting operation of the cork plates in slices over four sides

Female cork

Bark elaborated following the male bark stripping and the first female reproduction. This is the cork used by the cork industry.

First female bark

First female bark elaborated after stripping of the male cork. This cork is cracked and of less value.

Imputrefiable

Material that does not rot

Lenticel

Pores radically crossing the bark of the cork through its complete thickness. They form parallel lines over the slice of the cork and little dark points called grain by the cork manufacturers
Bot.: body of cells formed on the periderm of a stem, appearing on the surface of the plant as a lens-shaped pot, and serving as a pore.

Libber

Vegetal texture enabling by its perforated tubes the conduction of the elaborated sap, located in the deep part of the roots, in the stalk and in the stark of the trunk. See also phloem

Male cork

First bark produced by the tree ; the cork is improper to produce cork.

Medulla

Bot.: the pith of plants ; innermost part equivalent to middle
Anat.: the marrow like centre of an organ

Medullar

Pertaining to, consisting of, or resembling the medulla of an organ or the medulla

Meristem

Embryonic tissue; undifferentiated, growing actively dividing cells

Mother

Reproducible layer situated between the cork and the wood, which while growing furnishes wood towards the interior, and cork at the exterior. After stripping, the surface is reddish and becomes brown then black over time.

Nutgall

A nut like gall or excrescence, esp. one formed on an oak.

Oenology

the science of viniculture

Organo

An element of Greek origin used with the meaning "organ" or "organic" in the formation of compound words

Parenchyma

The fundamental tissue of plants, composed of thin-walled cells

Phelloderm

A layer of tissue in certain plants, formed from the inner cells of phellogen, base of the stalk or the root over its interior face and consisting usually of chlorenchyma

Phellogen

Cork cambium, a layer of vegetal tissue or secondary meristem external to the true cambium that produces the cork cells on the outside and phelloderm on the inside

Phloem

The part of a vascular bundle consisting of sleeve tubes, companion cells, parenchyma, and fibres and forming the food-conducting tissue of a plant.

Punching

Operation to extract the cork from the cork plate with a tool.

Sap

Liquid carrying food in the diverse parts of the plant or tree. One distinguishes the raw sap, that ascends by capillary roots towards the leaves, and the elaborated sap, produced by the leaves from the raw sap and which contains the organic supplies.

Stave

Each pieces of longitudinal wood assembled to form the body of a cask

Stripping

Removing of male cork from the cork oak tree performed in summer

Suber

Botanical designation of the cork, assembly of cells constituting the cork

Suboeno plant

Plantation of cork oak trees

Suberin

Bot.: a wax like fatty substance, occurring in cork cell walls and in or between other cells, that on alkaline hydrolysis yields chiefly suberic acid.
Substance covering the internal wall of the cork cells.

Tannin

Chem.: any of a group of astringent vegetable principles or compounds, as the reddish compound which gives the tanning properties to oak bark or the whitish compound which occurs in large quantities in nutgalls.

The assembly of savour composites for its astringency and colour element.

A reddish acid made from the bark used in preparing leather, ink. It is also found naturally in tea leaves, grape skins.

Tube

Cork under the form of a cleaved tube from a trunk stripped by one sole vertical cleft.

Viniculture

The science or study of making wine

Viticulture

The culture or cultivation of grapevines and grape-growing
The study of grapes and their culture

Xylem

The part of a vascular bindle consisting of tracheas, vessels, parenchyma cells, and fibres, and forming the woody tissue of a plant.
