Almond tree flowers
The almond is part of the Rosaceae family, species Prunus dulcis, genus Prunus, order Rosales, Class Magnoliopsida, division Magnoliophyta, Eukariota domain. It is native to the south-eastern part of Asia.
The general characteristics of the almond tree plant
First of all, in our discussion, the difference between almond and almond, often confused, must be immediately clarified. The first is a plant belonging to the Rosaceae family, while the second is only the seed that gives life to this plant. The almond tree looks like a tree that reaches the average height of 5 meters. Its roots are taproots. The first part of the stem is straight and gray, while the next part appears twisted and darker in color. The leaves are lanceolate, long up to 10-12 cm. In special cases it can also reach a height of 10 meters. The almond tree can be fragile (of sweet seed but with a non-wood endocarp), sweet (its seeds are used to make an excellent officinal oil) or bitter (it has seeds that are toxic). It was introduced in Sicily by the Phoenicians but, according to our information, it came from Greece and in fact the ancient Romans called it Greek walnut. From Sicily, where it was immediately appreciated, it quickly spread to all the Mediterranean countries, achieving considerable success.
The almond blossom. The peculiarities of its flowers
Its flowers are white or pink. They have a diameter of about 5 cm and 5 are also the petals and the sepals. On three whorls there are 40 stamens and a pistil with an ovary, which has two embryonic sacks containing 1 or 2 ovules each. The almond tree flowers are called hermaphrodites. It is a very long-lived plant, so over the years it ensures the production of considerable amounts of fruit. It has a rather expanded root system. The fruit that gives this plant is a generally hairy berry, but also hairless. This plant has an entomophilous fertilization and therefore it is necessary the presence of hives in the fundamental period of flowering, for the fertilization operations according to nature.
Tips for proper cultivation. The main known varieties
From the climatic point of view the best conditions for cultivating this plant exist in areas with a temperate climate, where frosts that put the development of almond trees at risk are rare.
During the cultivation phase the classic pruning operations must be limited to the maximum, in order to favor an early production activity of the almond trees.
Among the known varieties of this plant we must mention: the GF 677, propagated in vitro and very productive; the PS A6, less resistant to drought and limestone than the GF 677; the Franco, which is obtained from bitter or sweet almond seeds, very resistant and therefore suitable for soils subject to frequent drought, also manages to generate excellent quality fruit.
The fruit harvest can be done between August and September. In America the so-called mechanical collection has become established, which in our country has yet to be introduced on a large scale. After being harvested, the fruits are sliced and then dried. To improve the appearance of the fruits, they can be bleached with the use of sulfur dioxide. Noteworthy is the use of almond in the dried fruit sector, but also in the preparation of nougat and confetti traditionally used during various and important official ceremonies.
Enemies and remedies (non-polluting) to be implemented to preserve the health of the plant
In the south of Italy the declared enemy of this plant is a particular beetle called Capnodis tenebrionis. It is capable of causing serious damage, since it digs tunnels inside the trunks of individual plants. It is important to understand that the fight against pests that can infest the plant must be carried out by limiting the use of insecticides as much as possible, on the contrary favoring the repopulation of predatory birds.
The damage caused by scale insects, moths and various aphids can be limited without resorting to pesticides, which are very effective but also pollutants for the environment in which the plants are grown.
Endocarps are also used for some varieties of this plant, ie the innermost part of the fruits, where the seed is contained. Once incinerated, they are used to produce very appreciated soaps for their nutritional qualities for the benefit of the skin.
Some curiosity about the almond tree. Little known uses of this plant
We conclude our discussion, hoping to have given you useful information, with a curiosity: in the heraldry (science that studies the coats of arms and therefore the nobility of a family) the almond is given a meaning of manifestation of great courage, but also of youthful impetus . And therefore it is seen as a positive icon, a good omen for the prosperity and security of a family unit.
What's more, this fruit was even chosen by theologians as a symbol of Mary's virginity.
