THE ORIGIN AND THE DIFFERENT TYPES OF HAZELNUT
The hazelnut is actually the fruit of hazel, plant of the family of Betulaceae, a bush high, that grows naturally in almost all of Europe, Asia Minor, and also part of North America. This fruit is relatively rounded, it has the consistency of wood, the bark pretty solid, and is surrounded by a coating of leaves. In its interior is the seed edible, taste slightly sweet.
The Turkey, followed by Italy and the United States, are the three countries that produce hazelnut worldwide.
In Portugal, it is grown mainly in the northern region. Is found in forests and woodlands, but also in parks and gardens, banks of streams and hedges. The majority of the Portuguese acquired the hazelnuts are already ready to eat.
There are two main species of hazelnut:
- Corylus avellanais found in the wild state in western Europe and in England;
- Corylus maxima isnative to southeastern Europe and western Asia.
However, there are many hybrids of these two species difficult to be distinguished, and all known as hazel.
In Turkey there is a native species Corylus colurna that form trees of up to 25 metres in height which produces nuts of very large and valued commercially. There are also species of Corylus native to Canada, from China and Japan with fruit is far less than the european species, but also very important as food throughout the history of mankind. The species Corylus americana, native to North America, produces fruits long with hard shell and smaller than the other species of hazel.
The fruits of the hazel are produced in clusters of 1 to 10 fruits that will loosen the nuts when the wrappers dry and open.
A hazel produces from 6 to 12 kg of hazelnuts per year depending on climatic conditions and cultivation. The trees in production tend to switch to production every 2 or 3 years and, in this way, one should perform the pruning of the branches new and the removal of fruits new. In addition, they must be removed from the fruits that remained in the tree for which there is no inhibition in the formation of new flowers.
