Orange

Features

Orange is one of the best known trees in the world, due to the fact that its fruits, better known as oranges, have the particular characteristic of being remarkably widespread in the kitchens of the entire planet.

Orange is nothing more than a fruit tree that is part, like many other plants, of the large Rutaceae family.

It is a plant that can easily reach ten meters in height: as regards the leaves, it is important to underline that they have a typically elongated shape and are extremely fleshy.

Among the main characteristics of this fruit tree, we find evergreen shoots, with a typical color that in no case tends to reddish.

For lovers of curiosities, the period in which this fruit tree rests corresponds to only three months during the year: this explains the reason why the orange has the ability to provide for flowering and fruiting in the same period.


Origin

The orange plant is characterized by coming essentially from the Asian continent, or from two nations such as China and Japan, although nowadays it can be found with enormous ease in almost the entire Mediterranean basin, such as in Spain, for example. Italy and Greece.

Precisely in Italy, this fruit tree was brought by the Arabs and then the introduction took place by the merchants of Genoese origin, who had frequent contacts with the Asian coasts.

In particular, it seems that the orange has had a notable diffusion in the Italian peninsula in the period corresponding to the fourteenth century, especially in the region of Sicily, where for centuries the orange groves have been integrally part of the wonderful landscape that distinguishes those places.

Fruits

Currently, we can easily recognize orange as the most widespread citrus title in the whole planet, given that dozens and dozens of varieties of this fruit tree are cultivated.

Oranges are a typically winter fruit and, for this reason, the harvest begins during the month of November and an adult fruit tree can reach a production of 500 oranges in a year.

The edible part of oranges is represented by the endocarp, which is none other than the pulp, which is divided into various juicy wedges, while the peel is, in most cases, made up of a certain roughness.


Property

Oranges are a good source of vitamins, since they contain C and A in particular, but they also contain a significant amount of vitamins that are part of the B group.

We must not forget how the daily intake of 2-3 oranges allows us to cover the daily requirement for vitamin C.

It is precisely due to the importance of vitamin C that oranges are very important in restoring enamel and luster to the immune system.

The consumption of a good number of oranges during the winter season can be a good way to avoid being affected by seasonal diseases, such as colds and flu.

Furthermore, the high presence of bioflavonoids also allows it to play an active and stimulating role in the reconstitution of the collagen that forms the connective tissue.

This explains the reason why oranges are also very useful for strengthening bones, teeth, tendons and ligaments.

In any case, the consumption of oranges can also be particularly suitable for combating a large number of diseases that are caused by problems affecting the circulatory system.


Orange: Use

Bitter oranges, which are distinguished from sweet oranges by different characteristics (obviously including the flavor of the pulp) are frequently used in the food and pharmaceutical industries.

As for oranges, referring to whole fruits, they are mainly used for making jams and candied fruit.

The peel of oranges, on the other hand, has the advantage of being exploited for the preparation of numerous compounds in liqueurs (especially bitters).

The pharmaceutical industry also exploits the properties and qualities of oranges, since the peel is used in particular, with which various digestives and tonics are made.

As for the peel of bitter oranges, especially due to the rather marked presence of synephrine, its use is particularly aimed at the food supplement industry.

The infusion of orange peel is particularly suitable due to its digestive and aperitif properties.

The decoction is also interesting, which can be obtained from one or more orange peels, by placing them inside a container of 100 ml of water: the main purpose is to carry out a beneficial action and aid in proper digestion, to the point that it also manages to reduce various pains that affect the stomach.



Orange in the garden, how to grow it

Unlike lemon, which can also be easily grown in pots throughout Northern Italy because it can withstand lower temperatures, orange is more sensitive to cold and, consequently, in Northern Italy it can be bred in pot only in the less cold areas, such as those of the large lakes and, of course, on the Ligurian Riviera and the upper Tyrrhenian coasts.

How orange is made

The Orange (Citrus sinensis) is an evergreen tree up to 10 m tall, with branched trunk in 3-4 main branches. THE branches have a thorn in the axil of the leaves. The leaves they are oval, oblong, leathery, dark green in color. THE flowers ("Zagare") are white, formed by 5 sepals and 5 petals. There flowering it varies from February-March to summer, as does the ripening of the fruit, from autumn to spring of the following year.

The fruit it is a berry called "hesperidium" with a thin orange skin, a spongy and white albedo, a pulp with segments separated by septa. Based on the pulp color we can distinguish blond oranges and red or blood oranges (pigmented). Based onripening period the fruits are also classified as early, medium and late.

The color of the peel of oranges, in addition to the varietal characteristics, is instead influenced by the soil, climate and cultivation conditions: in general, the basically heavy soils, preferably with a good amount of limestone, favor a more accentuated color of the skin, which will result in a beautiful bright orange.

Between blonde varieties of oranges we recommend Belladonna, Biondo Comune, Ovale Calabrese and Vanilla (if you like the aftertaste) among the cultivars red, Moro, common Sanguinello and Tarocco.

How to grow it

  • THE rootstocks the most common for orange arebitter orange (Citrus aurantium), on loose, sandy-loamy and slightly clayey soils, with good resistance to frost, for plants with moderate to high vigor Volkamerian lemon (C. volkameriana), on loose or sandy soils, with good resistance to frost, for large fruit, abundant but of modest quality.trifoliate orange(Citrus = Poncirus trifoliata), on medium-textured soils, not calcareous, resistant to freezing, with good production in terms of quantity and quality, perfect for growing in pots.
  • It lives in the open ground all year round only in Liguria, Campania, Calabria and Sicily. North in winter it goes grown in pots to be protected in a special greenhouse, called "orangery", equipped with movable glass that is removed during the summer. Can't stand the cold (winter minimum +5 ° C with dry land), it needs a mild and not very variable climate during the year. THE twenty persistent can cause serious damage. Hopefully you can expect adequate windbreak devices live (prickly pear, maritime pine, bamboo, etc.) or artificial (trellises, absorption nets, etc.).
  • It does not tolerate i soils very clayey or too calcareous. There position it must be sunny.
  • The best time for the plant it is the beginning of spring. The planting hole goes fertilized with manure or other organic fertilizer to which ammonium sulphate, mineral superphosphate and potassium sulphate are added. Keep the graft point above the ground. The plant distances must be at least 4 m in the row and between the rows.
  • Irrigation it is essential, otherwise the plants grow little, do not bloom, the small fruits fall or, if they develop, remain small: in the cultivation areas it begins at the beginning of May and lasts until the end of September-October.
  • There fertilization with organic substance it must be repeated every two-three years annually, a chemical fertilizer with nitrogen, phosphorus and potassium must be supplied in autumn-winter.
  • There form of farming traditional is the globe with full crown, low deck at 20-30 cm above the graft starting from a plant already impaled at the base with 3-4 branches, inclined 60 ° with respect to the vertical, symmetrical and with insertion points approximately distant 10-15 cm from each other.
  • There pruning it is carried out in spring-summer every year. The relationship between vegetation and production must not be altered: excessive cuts favor the vegetation to the detriment of fruiting. We are limited to lighten the hair eliminating dry, broken or weakened branches after they have already bloomed or those curved down and yes they eliminate the numerous vertical shoots which develop vigorously and tend to take over the branches.
  • The graft crown is used on large diameter stems or branches, also to re-graft plants whose productivity has decreased or to change the cultivated variety.
