Pistachio nuts are usually sold in small bags so that the price does not bite so much. After all, not so many tasty and nutritious nuts are harvested all over the world, and therefore they are highly valued. Although the Pistachio tree is very unpretentious and could grow equally well in the hot desert and in the frosty North
Amazing plant
The Pistachio fruit tree grows very slowly. He has nowhere to rush, because the tree is one of the few plant centenarians on the planet, indifferently observing the change of centuries. Valuable wood can grow for a millennium, if artisans do not cut down a tree at the root in order to make exclusive crafts from dense decorative wood.
There is no other fruit tree on Earth that tolerates drought as hard as Pistachio does. Over the millennia, the tree has developed a special tactic of behavior: when the cloudless sky does not promise life-giving moisture, and the sun's rays heat the soil to 70 degrees Celsius, the pistachio stops growing. That is why the age of the tree is long.
The leaves of the tree, heated by the sun, stop evaporating water. Moreover, in order to cool the leaves, the plant begins to evaporate volatile resins instead of moisture. If you bring the flame of a match to such a sheet, then flammable vapors will flare up around the sheet.
Surprisingly, not only Pistachio can tolerate heat, but also cold. In the literature, you can find different minus limits that a tree can withstand. Some limit it to 25 degrees, others increase the limit to 40 degrees below zero. I don’t know how the test of the frost resistance of Pistachios was done, because I had never heard that, for example, in Siberia, someone grew such a tree. But, who knows, maybe there are such craftsmen.
As for desert lands with soil rich in calcium compounds, as well as loose limestone slopes, they would be happy to shelter Pistachio trees, whose powerful roots spread both in breadth and in depth, strengthening the soil.
The main value of Pistachios
Pistachio has many advantages, but the main value for a person is nuts - the seeds of the fruit of the tree. In a hard, but thin and easily split into two shells shell, a light green nucleolus of a peculiar shade is hidden, which is called so,"
pistachio ».
The nucleolus is rich in fats, proteins and carbohydrates, and therefore very nutritious and tasty. Nuts are eaten raw, or, soaked in salt water, they are fried, from which they acquire the taste of coffee. The kernels are added to pastries, chocolate, ice cream and even smoked sausage, turning the best varieties into gourmet delicacies.
Pistachio oil is made from fats, which make up 50 percent of the content in the nucleoli, which in its taste and nutritional qualities is not inferior to olive oil.
Unusual harvest time
Wild pistachio thickets are the main suppliers of fruits. Although in the culture Pistachio has been known since the third millennium BC, when it was grown in the gardens of Babylon and Assyria. Of course, the harvest of cultivated plants is incomparable with the harvest of wild plantings. One tree gives up to 250 kilograms of nut, while wild plants, covering an area of 1 hectare, endow 25 kilograms. The world harvest of Pistachio fruits is small, about 30,000 tons are harvested per year.
To avoid the effects of the volatile resins evaporated by the tree, the nuts are harvested late in the evening or early in the morning, when the sun has not yet begun its exhausting work.
Useful aphid
It turns out that annoying aphids do not always bother gardeners, reducing yields and spoiling ornamental plants. From injections of aphids living on Pistachio trees, growths are formed on the leaves, called in different places in different ways: “
Gauls" or"
buzguncha ».
People collect such growths and prepare bright dyes from them for wool and silk.
In addition, buzguncha is the best source for obtaining medical tannin, which is used to treat inflammation in the oral cavity, bedsores and burns.
